We study a structural model of individual bank defaults across the banking sector; banks are interconnected through their exposure to a common risk factor. The paper introduces a systemic risk measure based on the default frequency in the banking sector; this measure depends non-linearly on the factor's loadings, in contrast to previous systemic risk measures that depend linearly on loadings. We estimate loadings in the U.S. banking system over the course of the last 36 years; we find that they have considerably increased over time and identify four major regimes. Our measure shows that systemic risk became critical in the last of our four regimes, covering the most recent time period from 05/2007 to 09/2016. The empirical findings highlight that our measure complements existing systemic risk measures.

This paper analyzes various channels of shock transmission in an economy subject to financial frictions, by incorporating liquidity and default effects on asset prices. We develop a framework in which we can assess financial stability policy by introducing a simplified model of exchange and financial intermediation that captures the effects of shocks on financial and real sectors of the economy. The model allows us to explain essential mechanisms and interactions of financial and real economic variables in a comprehensive, yet intuitive fashion. Our results suggest that liquidity and default in the credit markets should be analyzed contemporaneously when financial, monetary and productivity shocks affect financial stability as well as the real economy.

Investment spending by US public firms is highly concentrated. The 100 largest spenders account for 60% of total capital expenditures and drive most of the variation in aggregate investment. This high concentration creates a disconnect between the average public firm and macroeconomic aggregates. For large firms, cash flow remains the primary driver of investment spending and has not declined in importance as it has for smaller public firms. The cash flowing to big spenders provides a better forecast of future investment opportunities than noisy proxies for Tobin's q even though these firms are not financially constrained. These results suggest that, at least for the largest spenders, it is unlikely that measurement error drives the significance of cash flow. Our results are also inconsistent with recent models that predict higher investment-cash flow sensitivity for small young growth firms and suggest that cash flow is still the most important determinant of macroeconomic fluctuations in investment spending.

Using international listed banks from the United States, Europe, Japan and China from 2004 to 2014, we analyze the effect on banks’ risk of some of the most relevant new elements of the prudential regulatory framework proposed after the Financial Crisis. We measure risk by a market measure, the volatility of banks’ stock returns. We also examine the effect of government support during the financial crisis and designation as a G-SIB. We find little support for an association with government support and none for a negative relationship. We find support for a positive effect of designation as a G-SIB on risk. We find a positive association with securities trading and a negative association with capital. Banks´ chosen liquidity is unimportant for this measure of risk.

Being hired into a job depends not only on one’s own skill but also on that of other applicants. When another able applicant applies, a well-suited worker may be forced into unemployment or into accepting an inferior job. A model of this process defines over- and underqualification and provides predictions on its prevalence and on the wages of mismatched workers. It also implies that unemployment is concentrated among the least skilled workers, while vacancies are concentrated among high-skilled jobs. Four data sets are used to confirm the implications and establish that the hiring probability is low when competing applicants are able.

Most discussions of the Greek debt overhang have focussed on the implications for Greece. We show that when additional funds released to the debtor (Greece), via debt restructuring, are used efficiently in pursuit of a practicable business plan, then both debtor and creditor can benefit. We examine a dynamic two country model calibrated to Greek and German economies and support two-steady states, one with endogenous default and one without, depending on creditors’ expectations. In the default steady state, debt forgiveness lowers the volatility of both German and Greek consumption whereas demanding higher recovery rates has the opposite effect. In a second order approximation of the model, conditional welfare analysis shows that a policy of immediate leniency followed by harsher terms as the economy grows is beneficial to both creditors and debtors.
