The Latest NBER Working Papers http://www.nber.org/new.html Goldin and Katz's The Race between Education and Technology is a monumental achievement that supplies a unified framework for interpreting how the demand and supply of human capital have shaped the distribution of earnings in the U.S. labor market over the 20th century. This essay reviews the theoretical and conceptual underpinnings of this work and documents the success of Goldin and Katz's framework in accounting for numerous broad labor market trends. The essay also considers areas where the framework falls short in explaining several key labor market puzzles of recent decades and argues that these shortcomings can potentially be overcome by relaxing the implicit equivalence drawn between workers' skills and their job tasks in the conceptual framework on which Goldin and Katz build. The essay argues that allowing for a richer set of interactions between skills and technologies in accomplishing job tasks both augments and refines the predictions of Goldin and Katz's approach and suggests an even more important role for human capital in economic growth than indicated by their analysis. http://papers.nber.org/papers/w17820#fromrss http://papers.nber.org/papers/w17820#fromrss Financial decisions, be they related to asset building or debt management, require the capacity to do calculations, including some complex ones. But how numerate are individuals, in particular when it comes to calculations related to financial decisions? Studies and surveys implemented in both the United States and in other countries that are described in this paper show the level of numeracy among the population to be very low. Moreover, lack of numeracy is not only widespread but is particularly severe among some demographic groups, such as women, the elderly, and those with low educational attainment. This has potential consequences for individuals and for society as a whole because numeracy is found to be linked to many financial decisions. Now more than ever, numeracy and financial literacy are lifetime skills necessary to succeed in today's complex economic environment. http://papers.nber.org/papers/w17821#fromrss http://papers.nber.org/papers/w17821#fromrss The regulation of bank capital as a means of smoothing the credit cycle is a central element of forthcoming macro-prudential regimes internationally. For such regulation to be effective in controlling the aggregate supply of credit it must be the case that: (i) changes in capital requirements affect loan supply by regulated banks, and (ii) unregulated substitute sources of credit are unable to offset changes in credit supply by affected banks. This paper examines micro evidence--lacking to date--on both questions, using a unique dataset. In the UK, regulators have imposed time-varying, bank-specific minimum capital requirements since Basel I. It is found that regulated banks (UK-owned banks and resident foreign subsidiaries) reduce lending in response to tighter capital requirements. But unregulated banks (resident foreign branches) increase lending in response to tighter capital requirements on a relevant reference group of regulated banks. This "leakage" is substantial, amounting to about one-third of the initial impulse from the regulatory change. http://papers.nber.org/papers/w17822#fromrss http://papers.nber.org/papers/w17822#fromrss In the summer of 2010, the Federal Reserve's and the Swedish Riksbank's inflation forecasts were below the former's mandate-consistent rate and the latter's target, respectively, and their unemployment forecasts were above sustainable rates. Given the mandates of the Federal Reserve and the Riksbank, conditions in both countries clearly called for policy easing. The Federal Reserve maintained a minimum policy rate, soon started to communicate possible future easing, and in the fall launched QE2. In contrast, the Riksbank started a period of rapid tightening. I examine the arguments that were raised in opposition to the Federal Reserve's easing, and those for the Riksbank's tightening. Although the Swedish economy subsequently performed better than expected, probably an important reason was that the market implemented much easier financial conditions than were consistent with the Riksbank's policy rate path. Without the policy tightening, performance would have been even better. The U.S. economy meanwhile performed worse than expected because of factors other than monetary policy. Without the policy easing, performance would have been even worse. Thus, the Federal Reserve appears to have followed its mandate in the summer of 2010, and subsequent adverse economic shocks contributed to weak performance of the U.S. economy. In contrast, the Riksbank appears to have deviated from its mandate, but favorable circumstances contributed to an economic outcome with better performance than might have been expected based on policy choices. http://papers.nber.org/papers/w17823#fromrss http://papers.nber.org/papers/w17823#fromrss Many analysts have considered whether households approaching retirement age have accumulated enough assets to be well prepared for retirement. In this paper, we shift from studying household finances at the start of the retirement period, an ex ante measure of retirement preparation, to studying the asset holdings of households in their last years of life. The analysis is based on Health and Retirement Study with special attention to Asset and Health Dynamics Among the Oldest Old (AHEAD) cohort that was first surveyed in 1993. We consider the level of assets that households hold in the last survey wave preceding their death. We study how assets at the end of life depend on three family status pathways prior to death-- (1) original one-person households in 1993, (2) persons in two-person household in 1993 with a deceased spouse in the last year observed, and (3) persons in two-person households in 1993 with the spouse alive when last observed. We find that a substantial fraction of persons die with virtually no financial assets--46.1 percent with less than $10,000--and many of these households also have no housing wealth and rely almost entirely on Social Security benefits for support. In addition this group is disproportionately in poor health. Based on a replacement rate comparison, many of these households may be deemed to have been well-prepared for retirement, in the sense that their income in their final years was not substantially lower than their income in their late 50s or early 60s. Yet with such low asset levels, they would have little capacity to pay for unanticipated needs such as health expenses or other financial shocks or to pay for entertainment, travel, or other activities. This raises a question of whether the replacement ratio is a sufficient statistic for the "adequacy" of retirement preparation. http://papers.nber.org/papers/w17824#fromrss http://papers.nber.org/papers/w17824#fromrss Barcodes and barcode scanners transformed the grocery industry in the 1970s. I use store-level data from the 1972, 1977, and 1982 Census of Retail Trade, matched to data on store scanner installations, to estimate scanners' effect on labor productivity. I find that early scanners increased a store's labor productivity, on average, by approximately 4.5 percent in the first few years. The effect was larger in stores carrying more packaged products, consistent with the presence of network externalities. Short-run gains were small relative to fixed costs, suggesting that the impediment to widespread adoption of the new technology was profitability, not coordination problems. http://papers.nber.org/papers/w17825#fromrss http://papers.nber.org/papers/w17825#fromrss Numerical simulation analysis of bargaining solutions is little developed in existing literature. Here we use a multi country, single period numerical general equilibrium model which captures China and her major trading partners and examine the outcomes of trade policy bargaining solutions (bargaining over tariffs and financial transfers) over time as China grows more rapidly than her trade partners. We compute gains relative to non-cooperative Nash equilibria for a range of model parameterizations. This yields a measure of both absolute and relative gain to China from bargaining. We calibrate our model to base case data for 2008 and use a model formulation where there are heterogeneous goods across countries. The gains from trade bargaining accrue more heavily to other countries when we use 2008 data rather than later year data. We then consider the impacts out into the future of different country growth rates which sharply increases China's relative size. Our objective is to assess how China's gains from bargaining change over time; whether they grow at a faster rate than GDP growth and for which parameterizations. Our simulation results indicate that China's welfare gain from trade bargaining will increase over time if countries keep their present GDP growth rates for several decades, but there are major difference when using different bargaining solution concepts. These differences have not been noted in existing literature but have an intuitive explanation. Our results also indicate that if China jointly bargains along with India, Brazil and other developing countries with the OECD, China's gain will further increase. Bargaining gains are also sensitive to country size. When we use PPP to adjust China's relative GDP size; China's trade bargaining welfare gain increases by about 37%. http://papers.nber.org/papers/w17826#fromrss http://papers.nber.org/papers/w17826#fromrss We use administrative data from five states to provide the first comprehensive estimates of the size of the for-profit higher education sector in the U.S. Our estimates include schools that are not currently eligible to participate in federal student aid programs under Title IV of the Higher Education Act and are therefore missed in official counts. We find that the number of for-profit institutions is double the official count and the number of students is between one-quarter and one-third greater. Many for-profit institutions that are not Title IV eligible offer programs and certificates that are similar, if not identical, to those given by institutions that are part of Title IV. We find that the Title IV institutions charge tuition that is about 75 percent higher than that charged by comparable institutions whose students cannot apply for federal financial aid. The dollar value of the premium is about equal to the amount of financial aid received by students in eligible institutions, lending credence to the "Bennett hypothesis" that aid-eligible institutions raise tuition to maximize aid. http://papers.nber.org/papers/w17827#fromrss http://papers.nber.org/papers/w17827#fromrss We provide a comprehensive review of China's financial system, and explore directions of future development. First, the financial system has been dominated by a large banking sector. In recent years banks have made considerable progress in reducing the amount of non-performing loans and improving their efficiency. Second, the role of the stock market in allocating resources in the economy has been limited and ineffective. We discuss issues related to the further development of China's stock market and other financial markets. Third, the most successful part of the financial system, in terms of supporting the growth of the overall economy, is a non-standard sector that consists of alternative financing channels, governance mechanisms, and institutions. The co-existence of this sector with banks and markets can continue to support the growth of the Hybrid Sector (non-state, non-listed firms). Finally, among the policies that will help to sustain stable economic growth in China are those that reduce the likelihood of damaging financial crises, including a banking sector crisis, a real estate or stock market crash, and a "twin crisis" in the currency market and banking sector. http://papers.nber.org/papers/w17828#fromrss http://papers.nber.org/papers/w17828#fromrss Casual empiricism suggests that deceptive advertising about product quality is prevalent, and several classes of theories explore its causes and consequences. We provide some unusually sharp empirical evidence on the extent, mechanics, and dynamics of deceptive advertising. Ski resorts self-report substantially more natural snowfall on weekends. Resorts that plausibly reap greater benefits from exaggerating do it more. Data on website visits suggests that consumers are appropriately skeptical of weekend reports. We find little evidence that competition restrains or encourages exaggeration. Near the end of our sample period, a new iPhone application feature makes it easier for skiers share information on ski conditions in real time. Exaggeration falls sharply, especially at resorts with better iPhone reception. http://papers.nber.org/papers/w17829#fromrss http://papers.nber.org/papers/w17829#fromrss A drop in aggregate demand driven by shocks to household balance sheets is responsible for a large fraction of the decline in U.S. employment from 2007 to 2009. The aggregate demand channel for unemployment predicts that employment losses in the non-tradable sector are higher in high leverage U.S. counties that were most severely impacted by the balance sheet shock, while losses in the tradable sector are distributed uniformly across all counties. We find exactly this pattern from 2007 to 2009. Alternative hypotheses for job losses based on uncertainty shocks or structural unemployment related to construction do not explain our results. Using the relation between non-tradable sector job losses and demand shocks and assuming Cobb-Douglas preferences over tradable and non-tradable goods, we quantify the effect of aggregate demand channel on total employment. Our estimates suggest that the decline in aggregate demand driven by household balance sheet shocks accounts for almost 4 million of the lost jobs from 2007 to 2009, or 65% of the lost jobs in our data. http://papers.nber.org/papers/w17830#fromrss http://papers.nber.org/papers/w17830#fromrss Debtors bear the brunt of a decline in asset prices associated with financial crises and policies aimed at partial debt relief may be warranted to boost growth in the midst of crises. Drawing on the US experience during the Great Recession of 2008-09 and historical evidence in a large panel of countries, we explore why the political system may fail to deliver such policies. We find that during the Great Recession creditors were able to use the political system more effectively to protect their interests through bailouts. More generally we show that politically countries become more polarized and fractionalized following financial crises. This results in legislative stalemate, making it less likely that crises lead to meaningful macroeconomic reforms. http://papers.nber.org/papers/w17831#fromrss http://papers.nber.org/papers/w17831#fromrss We show that easier access to credit significantly increases house prices by using exogenous changes in the conforming loan limit as an instrument for lower cost of financing and higher supply. Houses that become eligible for financing with a conforming loan show an increase in house values of 1.1 dollars per square foot (for an average price per square foot of 224 dollars) and higher overall house prices controlling for a rich set of house characteristics. These coefficients are consistent with a local elasticity of house prices to interest rates below 10. In addition, loan to value ratios around the conforming loan limit deviate significantly from the common 80 percent norm, which confirms that it is an important factor in the financing choices of home buyers. In line with our interpretation, the results are stronger in the first half of our sample (1998-2001) when the conforming loan limit was more important, given that other forms of financing were less common and substantially more expensive. http://papers.nber.org/papers/w17832#fromrss http://papers.nber.org/papers/w17832#fromrss Much literature on political behavior treats politicians as motivated by reelection, choosing actions to signal their types to voters. We identify two novel implications of models in which signalling incentives are important. First, because incumbents only care about clearing a reelection hurdle, signals will tend to cluster just above the threshold needed for reelection. This generates a skew distribution of signals leading to an incumbency advantage in the probability of election. Second, voters can exploit the signalling behavior of politicians by precommitting to a higher threshold for signals received. Raising the threshold discourages signalling effort by low quality politicians but encourages effort by high quality politicians, thus increasing the separation of signals and improving the selection function of an election. This precommitment has a simple institutional interpretation as a supermajority rule, requiring that incumbents exceed some fraction of votes greater than 50% to be reelected. http://papers.nber.org/papers/w17833#fromrss http://papers.nber.org/papers/w17833#fromrss Each year, fourteen million households seeking federal aid for college complete a detailed questionnaire about their finances, the Free Application for Federal Student Aid (FAFSA). At 116 questions, the FAFSA is almost as long as IRS Form 1040 and substantially longer than Forms 1040EZ and 1040A. Aid for college is intended to increase college attendance by reducing its price and loosening liquidity constraints. Economic theory, empirical evidence and common sense suggest that complexity in aid could undermine its ability to affect schooling decisions. In 2006, Dynarski and Scott-Clayton published an analysis of complexity in the aid system that generated considerable discussion in academic and policy circles. Over the next few years, complexity in the aid system drew the attention of the media, advocacy groups, presidential candidates, the National Economic Council and the Council of Economic Advisers. A flurry of legislative and agency activity followed. In this article, we provide a five-year retrospective of what has changed in the aid application process, what has not, and the possibilities for future reform. http://papers.nber.org/papers/w17834#fromrss http://papers.nber.org/papers/w17834#fromrss This paper provides striking confirmation of the restrictions of the structural gravity model of trade. Structural forces predicted by theory explain 95% of the variation of the fixed effects used to control for them in the recent gravity literature, fixed effects that in principle could reflect other forces. This validation opens avenues to inferring unobserved sectoral activity and multilateral resistance variables by equating fixed effects with structural gravity counterparts. Our findings also provide important validation of a host of general equilibrium comparative static exercises based on the structural gravity model. http://papers.nber.org/papers/w17835#fromrss http://papers.nber.org/papers/w17835#fromrss From 2000 to 2003, when Ben Bernanke was a professor and then a Fed Governor, he wrote extensively about monetary policy at the zero bound on interest rates. He advocated aggressive stimulus policies, such as a money-financed tax cut and an inflation target of 3-4%. Yet, since U.S. interest rates hit zero in 2008, the Fed under Chairman Bernanke has taken more cautious actions. This paper asks when and why Bernanke changed his mind about zero-bound policy. The answer, at one level, is that he was influenced by analysis from the Fed staff that was presented at the FOMC meeting of June 2003. This answer raises another question: why did the staff's views influence Bernanke so strongly? I seek answers to this question in the social psychology literature on group decision-making. http://papers.nber.org/papers/w17836#fromrss http://papers.nber.org/papers/w17836#fromrss This paper provides new evidence on the effects of fiscal policy by studying, using household-level data, how households respond to shifts in government spending. Our identification strategy allows us to control for time-specific aggregate effects, such as the stance of monetary policy or the U.S.-wide business cycle. However, it potentially prevents us from estimating the wealth effects associated with a shift in spending. We find significant heterogeneity in households' response to a spending shock; the effects appear vary over time depending, among other factors, on the state of business cycle and, at a lower frequency, on the composition of employment (such as the share of workers in part-time jobs). Shifts in spending could also have important distributional effects that are lost when estimating an aggregate multiplier. Heads of households working relatively few (weekly) hours, for instance, suffer from a spending shock of the type we analyzed: their consumption falls, their hours increase and their real wages fall. http://papers.nber.org/papers/w17837#fromrss http://papers.nber.org/papers/w17837#fromrss Can banks maintain their advantage as liquidity providers when they are heavily exposed to a financial crisis? The standard argument - that banks can - hinges on deposit inflows that are seeking a safe haven and provide banks with a natural hedge to fund drawn credit lines and other commitments. We shed new light on this issue by studying the behavior of bank deposit rates and inflows during the 2007-09 crisis. Our results indicate that the role of the banking system as a stabilizing liquidity insurer is not one of the passive recipient, but of an active seeker, of deposits. We find that banks facing a funding squeeze sought to attract deposits by offering higher rates. Banks offering higher rates were also those most exposed to liquidity demand shocks (as measured by their unused commitments, wholesale funding dependence, and limited liquid assets), as well as with fundamentally weak balance-sheets (as measured by their non-performing loans or by subsequent failure). Such rate increases have a competitive effect in that they lead other banks to offer higher rates as well. Overall, the results present a nuanced view of deposit rates and flows to banks in a crisis, one that reflects banks not just as safety havens but also as stressed entities scrambling for deposits. http://papers.nber.org/papers/w17838#fromrss http://papers.nber.org/papers/w17838#fromrss U.S. investors are the largest group of international equity investors in the world, but to date conclusive evidence on which types of foreign firms are able to attract U.S. investment is not available. Using a comprehensive dataset of all U.S. investment in foreign equities, we find that the single most important determinant of the amount of U.S. investment a foreign firm receives is whether the firm cross-lists on a U.S. exchange. Correcting for selection biases, cross-listing leads to a doubling (or more) in U.S. investment, an impact greater than all other factors combined. We also show that our firm-level analysis has implications for country-level studies, suggesting that research investigating equity investment patterns at the country-level should include cross-listing as an endogenous control variable. We describe easy-to-implement methods for including the importance of cross-listing at the country level. http://papers.nber.org/papers/w17839#fromrss http://papers.nber.org/papers/w17839#fromrss This paper reviews recent developments in international trade to evaluate several arguments concerning the merits of preferential trade agreements (PTAs) and their place in the world trade system. Taking a multilateralist perspective, it makes several points: First, despite the proliferation of PTAs in recent years, the actual amount of liberalization that has been achieved through PTAs is actually quite limited. Second, at least a few studies point to significant trade diversion in the context of particular PTAs and thus serve as a cautionary note against casual dismissals of trade diversion as a merely theoretical concern. Equally, adverse effects on the terms-of-trade of non-member countries have also been found in the literature. Third, while the literature has found mixed results on the question of whether tariff preferences help or hurt multilateral liberalization, the picture is different with the more elastic tools of trade policy, such as antidumping duties (ADs); the use of ADs against non-members appears to have dramatically increased while the use of ADs against partner countries within PTAs has fallen. Fourth, despite the rapid expansion of preferences in trade, intra-PTA trade shares are relatively small for most PTAs; multilateral remain relevant to most member countries of the WTO. http://papers.nber.org/papers/w17840#fromrss http://papers.nber.org/papers/w17840#fromrss
