This paper investigates the importance of market incompleteness by comparing the rates of risk aversion estimated from complete and incomplete markets environments. For the incomplete-markets case, we use consumption data for 50 U.S. states. While the use of state-level data is conceptually...

In this paper, we document some key business cycle properties of foreign aid flows to developing countries. We identify two striking empirical regularities. First, aid flows are highly volatile over time -- on average, two to three times as volatile as the recipient's output. Second, for most...

Economic fluctuations are much stronger when measured at the state level than they are for the United States as a whole. This observation raises the question of how costly business cycles really are in the United States. Using state-level consumption data, we show that the welfare cost of...

Extant estimates of the welfare cost of business cycles suggest that this cost is quite low and might well be minuscule. Those estimates are based on consumption data for the United States as a whole. The volatility of aggregate consumption, however, is much stronger at the state level. We argue...

Official development assistance is a key source of external finance in many developing countries. A striking feature of these aid flows is their positive correlation with the business cycle of recipient countries. This pattern is puzzling in that it reinforces recipients' already strong and...

Existing estimates of the welfare cost of business cycles suggest that it is quite low and might well be minuscule. Many of these estimates are based on aggregate U.S. consumption data. Arguably, because markets are incomplete and risk-sharing is imperfect, the welfare costs computed with...

In this paper, we quantify foreign aid's potential as an insurance mechanism against macroeconomic shocks. Within a dynamic model of aid flows between two endowment economies, we show that at least three fourths of the large welfare costs of macroeconomic fluctuations in poor countries could be...

In this paper, we develop a methodology to summarize the various policy parameters of an unemployment insurance scheme into a single generosity parameter. Unemployment insurance policies are multdimensional objects. They are typically defined by waiting periods, eligibility duration, benefit...

In previous work, Pallage and Zimmermann (2010) document how an Unemployment Account system dominates an Unemployment Insurance system in many circumstances for a labor market like in the US if it is optimized. This paper reevaluates this in the context of a labor market with higher average...
