Nine out of the last ten recessions in the United States have been preceded by an increase in the price of oil as noted by Hamilton [Palgrave Dictionary of Economics]. Given the small share of energy in gross domestic product this phenomenon is difficult to explain using standard models. In this paper, I show that firm entry can be an important transmission and amplifying channel for energy price shocks. The results from the baseline dynamic stochastic general equilibrium (DSGE) model predict a drop in output that is two times the impact in a model without entry. The model also predicts an increase in energy prices would lead to a decline in real wages, investment, consumption, and return on investment. Additionally, using US firm level data, I demonstrate that a rise in energy prices has a negative impact on firm entry as predicted by the DSGE model. This lends further support toward endogenizing firm entry when analyzing the effects of energy price shocks.

Against the background of the emergence of macroeconomic imbalances within the European Monetary Union (EMU), we investigate in this paper the macroeconomic consequences of cross-border banking in monetary unions such as the Euro area. For this purpose, we incorporate a union-wide banking sector along the lines in an otherwise standard two-region monetary union DSGE model, accounting for borrowing constraints of entrepreneurs and impatient households and an internal constraint on the bank's leverage ratio. We illustrate in particular how rule-of-thumb lending standards based on the macroeconomic performance of the core region within the monetary union can translate into destabilizing spill-over effects into the other region, resulting in an overall higher macroeconomic volatility. Thereby, we demonstrate a channel through which the financial sector may have exacerbated the emergence of macroeconomic imbalances within the EMU. This effect may be mitigated by macroprudential policies, where especially policies that force the bank's lending standards to be less procyclical prove to be effective in stabilizing output in both regions of the monetary union.

We build a model that, according to the empirical evidence, gives rise to oscillations in wealth within a dynasty while keeping intergenerational persistence in education attainment. We propose a mechanism based on the interaction between wealth and effort as suggested by the Carnegie conjecture, according to which wealthier individuals devote less effort in their job occupations than poorer. Oscillations in wealth arise from changes in the occupation chosen by different generations of the same dynasty as a response to both inherited wealth and college premium. Our mechanism generates a rich social stratification with several classes in the long run due to the combination of different levels of education and occupation types. Furthermore, we generate a large mobility in wealth among classes even in the long run. Our model highlights the role played by the minimum cost on education investment, the borrowing constraints, and the complementarity between education and occupational effort.

This paper proposes a financial accelerator framework to study the effects of heterogeneous and bounded rational expectations on macroeconomic dynamics. The paper examines the fluctuations effects departing from the rational expectations hypothesis in order to understand if there are significant implications on macroeconomic volatility and policy prescriptions. The findings suggest that macroeconomic stability and inflation dynamics depend on the chosen set of forecasting rules, as well as on the monetary policy adopted. The model shows that no monetary policy is able to quickly stabilize the system, as some fluctuations persist. Central banks face a trade-off between macro-volatility and speed of convergence to the steady state. This result offers some ground for fiscal policies aiming to prompt system stability. In addition, the analysis reveals a counterintuitive result confirming the “less-is-more” effect: increasing the decision-making and computational abilities of the agents may not lead the system to converge to the preferable steady state.

This paper evaluates the effectiveness of short-time work (STW) extensions—e.g., relaxing eligibility criteria or implementing new schemes—in OECD countries during the Great Recession. First, we find that the dampening effect of STW on the unemployment rate diminishes at higher take-up rates. Second, only countries with pre-existing STW schemes were able to fully exploit the benefits of STW. Third, the effects of STW were strongest when GDP growth was deeply negative at the beginning of the recession. In summary, our results indicate that STW is most effective when used as a fast-responding automatic stabilizer.

We analyze in some detail the full predeposit game in a simple, tractable, yet very rich, banking environment. How does run-risk affect the optimal deposit contract? If there is a run equilibrium in the postdeposit game, then the optimal contract in the predeposit game tolerates small-probability runs. However, this does not mean that small changes in run-risk are ignored. In some cases, the optimal contract becomes—as one would expect—strictly more conservative as the run-probability increases (until it switches to the best run-proof contract), and the equilibrium allocation is not a mere randomization over the equilibrium allocations from the postdeposit game. In other cases, the allocation is a mere randomization over the equilibria from the postdeposit game. In the first cases (the more intuitive cases), the incentive constraint does not bind. In the second cases, the incentive constraint does bind.

This study estimates the response of macroeconomic variables to stock market fluctuations in Japan and the United States. It emphasizes the economy's reaction to stock market bubbles and crashes. To do this, I propose a new way to identify bubbles and crashes by testing price-to-fundamental ratios using the newly developed trend-filtering approach. Regardless of the measures used, both countries' macroeconomy tends to respond positively to the positive shock of stock price. Asymmetric effects of the stock market are observed. Japan's macroeconomic variables, especially investment and industrial production, are more sensitive to market crashes, while those of the United States are more sensitive to stock bubbles. Finally, I provide evidence that market sentiment can affect the economy either directly or indirectly through the stock market.

This paper shows empirical evidence and theory consistent with the US government using debt optimally to adjust the federal budget to news about long-term growth. First, using historical forecasts from the Congressional Budget Office (CBO) since 1984, I find that government purchases and deficits are positively correlated with expectations about long-term productivity, real gross domestic product, and tax revenue growth, whereas tax receipts are negatively correlated. A structural vector autoregression estimated with US quarterly data in 1955–2015 identifies permanent and transitory productivity shocks and points to “trend” shocks as the source of these correlations. Second, I present an open economy real business-cycle model with stochastic productivity trend and optimal public purchases and taxes. Calibrating the model to the US economy, the Ramsey planners' allocation yields moments aligned with those observed in the data.
