Dissecting Saving Dynamics
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.
After the Crisis
We estimate consumption dynamics in the G-7 economies, paying particular attention to the possibility of precautionary behavior in the face of uncertainty. We find that in the short run, continued income uncertainty will significantly dampen consumption growth. As such, consumption in the G-7 economies is unlikely to be the engine that revives global growth. Differences in the pace and timing of consumption moderation have implications for the evolution of global imbalances. With the U.S. experiencing a sharper rise in unemployment and, perhaps, more widespread loss of financial wealth than elsewhere in the G-7, the relative rise of the U.S. savings rate is helping narrow global imbalances. But with a likely earlier recovery in the U.S., this narrowing could be short-lived. Moreover, long-term differences- in economic and financial volatility and in demographic structures-have been an important source of the imbalances and could soon reassert their prominence.
The Decline in Saving
"Examines the decline in saving in the United States over the past quarter-century. Is it a statistical artifact of the official measure of saving? Why don't Americans save? What are the consequences for economic growth, the performance of the aggregate economy, and policy goals?"--Provided by publisher.
Hollowing Out: The Channels of Income Polarization in the United States
Data show that middle-income households have continued moving down, and less so up, the income distribution in the United States since the 1970s—a phenomenon that is often referred to as the polarization or “hollowing out” of the income distribution. While the level of income polarization is generally lower in the richer states (i.e., those with higher median household income levels), there have been wide variations in the changes in income polarization over time across states. The paper develops two indices to measure income polarization including a novel hollowing-out index. Another important contribution of the paper is to examine the proximate causes of income polarization. The eco...
Income Inequality
The first book-length treatment to conclusively demonstrate the link between income inequality and the 2008 financial crisis and Great Recession Prevailing economic theory attributes the 2008 crash and the Great Recession that followed to low interest rates, relaxed borrowing standards, and the housing price bubble. After careful analyses of statistical evidence, however, Matthew Drennan discovered that income inequality was the decisive factor behind the crisis. Pressured to keep up consumption in the face of flat or declining incomes, Americans leveraged their home equity to take on excessive debt. The collapse of the housing market left this debt unsupported, causing a domino effect throughout the economy. Drennan also found startling similarities in consumer behavior in the years leading to both the Great Depression and the Great Recession. Offering an economic explanation of a phenomenon described by prominent observers including Thomas Piketty, Jacob Hacker, Robert Kuttner, Paul Krugman, and Joseph Stiglitz, Drennan's evenhanded analysis disproves dominant theories of consumption and draws much-needed attention to the persisting problem of income inequality.

Inflation Expectations and the Supply Chain
We show that firms rely on price changes observed along their supply chain to form expectations about aggregate inflation, and that these expectations have a complete pass-through to sales prices. Leveraging a unique dataset on Chilean firms merging expectation surveys and records from the VAT and customs registries, we document that changes in prices at which firms purchase inputs inform their forecasts of the economy’s inflation. This is the case even if changes in input costs do not determine the inflation outcome. These findings reject the full-information rational-expectations hypothesis and are consistent with firms’ disagreement about future inflation and inattention to macroeconomic news, which we document for Chile. Our results from a firm-level Phillips’ curve estimation suggest that firms’ beliefs about inflation are a key determinant for their price-setting decisions. Therefore, we argue that the channel we highlight in this paper has the potential to lead to dispersion in inflation expectations, price dispersion, and weaken the expectation channel of policies.
Financial Crises
The lingering effects of the economic crisis are still visible—this shows a clear need to improve our understanding of financial crises. This book surveys a wide range of crises, including banking, balance of payments, and sovereign debt crises. It begins with an overview of the various types of crises and introduces a comprehensive database of crises. Broad lessons on crisis prevention and management, as well as the short-term economic effects of crises, recessions, and recoveries, are discussed.
The Economics of Consumption
In The Economics of Consumption, Tullio Jappelli and Luigi Pistaferri provide a comprehensive examination of the most important developments in the field of consumption decisions and evaluate economic models against empirical evidence.
Drivers of Post-COVID Private Consumption in the U.S.
Private consumption in the U.S. has recovered swiftly from the pandemic trough and has been running above the pre-pandemic trend even as interest rates rose sharply. This paper examines the underlying drivers for this strong growth in consumption. Using both state- and household-level data, we find that excess savings from the pandemic, large increases in household wealth (especially housing), along with solid real income gains contributed to strengthening post-pandemic consumption. Compared with pre-COVID estimates, the marginal propensity to consume out of housing wealth is substantially higher, which, together with large gains in housing prices, made the wealth effect a key driver for post-pandemic consumption growth.
