We argue that the U.S. personal saving rate’s long stability (from the 1960s through the early 1980s), subsequent steady decline (1980s - 2007), and recent substantial increase (2008 - 2011) can all be interpreted using a parsimonious ‘buffer stock’ model of optimal consumption in the presence of labor income uncertainty and credit constraints. Saving in the model is affected by the gap between ‘target’ and actual wealth, with the target wealth determined by credit conditions and uncertainty. An estimated structural version of the model suggests that increased credit availability accounts for most of the saving rate’s long-term decline, while fluctuations in net wealth and uncertainty capture the bulk of the business-cycle variation.

This paper analyzes the extent of income inequality from a global perspective, its drivers, and what to do about it. The drivers of inequality vary widely amongst countries, with some common drivers being the skill premium associated with technical change and globalization, weakening protection for labor, and lack of financial inclusion in developing countries. We find that increasing the income share of the poor and the middle class actually increases growth while a rising income share of the top 20 percent results in lower growth—that is, when the rich get richer, benefits do not trickle down. This suggests that policies need to be country specific but should focus on raising the income share of the poor, and ensuring there is no hollowing out of the middle class. To tackle inequality, financial inclusion is imperative in emerging and developing countries while in advanced economies, policies should focus on raising human capital and skills and making tax systems more progressive.

The paper studies how high leverage and crises can arise as a result of changes in the income distribution. Empirically, the periods 1920-1929 and 1983-2008 both exhibited a large increase in the income share of the rich, a large increase in leverage for the remainder, and an eventual financial and real crisis. The paper presents a theoretical model where these features arise endogenously as a result of a shift in bargaining powers over incomes. A financial crisis can reduce leverage if it is very large and not accompanied by a real contraction. But restoration of the lower income group's bargaining power is more effective.

We study the effects and historical contribution of monetary policy shocks to consumption and income inequality in the United States since 1980. Contractionary monetary policy actions systematically increase inequality in labor earnings, total income, consumption and total expenditures. Furthermore, monetary shocks can account for a significant component of the historical cyclical variation in income and consumption inequality. Using detailed micro-level data on income and consumption, we document the different channels via which monetary policy shocks affect inequality, as well as how these channels depend on the nature of the change in monetary policy.

The definitive account of the trillion-dollar payment card industry. The payment card business has evolved from its inception in the 1950s as a way to handle payment for expense-account lunches (the Diners Club card) into today's complex, sprawling industry that drives trillions of dollars in transaction volume each year. Paying with Plastic is the definitive source on an industry that has revolutionized the way we borrow and spend. More than a history book, Paying with Plastic delivers an entertaining discussion of the impact of an industry that epitomizes the notion of two-sided markets: those in which two or more customer groups receive value only if all sides are actively engaged. New to this second edition, the two-sided market discussion provides useful insight into the implications of these market dynamics for cardholder rewards, merchant interchange fees, and card acceptance. The authors, both of whom have researched the industry for more than 25 years, also examine the implications of the recent antitrust cases on the industry as well as other business and technological changes—including the massive consolidation brought about by bank mergers, the rise of the debit card, and the emergence of e-commerce—that could alter the payment card industry dramatically in the years to come.

We posit that the relationship between income inequality and economic growth is mediated by the level of equality of opportunity, which we identify with intergenerational mobility. In economies characterized by intergenerational rigidities, an increase in income inequality has persistent effects—for example by hindering human capital accumulation— thereby retarding future growth disproportionately. We use several recently developed internationally comparable measures of intergenerational mobility to confirm that the negative impact of income inequality on growth is higher the lower is intergenerational mobility. Our results suggest that omitting intergenerational mobility leads to misspecification, shedding light on why the empirical literature on income inequality and growth has been so inconclusive.

We analyze the employment effects of financial shocks using a rich data set of job contracts, matched with the universe of firms and their lending banks in one Italian region. To isolate the effect of the financial shock we construct a firm-specific time-varying measure of credit supply. The contraction in credit supply explains one fourth of the reduction in employment. This result is concentrated in more levered and less productive firms. Also, the relatively less educated and less skilled workers with temporary contracts are the most affected. Our results are consistent with the cleansing role of financial shocks.

This volume seeks to go beyond the microeconomic view of wages as a cost having negative consequences on a given firm, to consider the positive macroeconomic dynamics associated with wages as a major component of aggregate demand.

Is there a tradeoff between raising growth and reducing inequality and poverty? This paper reviews the theoretical and empirical literature on the complex links between growth, inequality, and poverty, with causation going in both directions. The evidence suggests that growth can be effective in reducing poverty, but its impact on inequality is ambiguous and depends on the underlying sources of growth. The impact of poverty and inequality on growth is likewise ambiguous, as several channels mediate the relationship. But most plausible mechanisms suggest that poverty and inequality reduce growth, at least in the long run. Policies play a role in shaping these relationships and those designed to improve equality of opportunity can simultaneously improve inclusiveness and growth.
