Rabin proved that a low level of risk aversion with respect to small gambles leads to a high, and absurd, level of risk aversion with respect to large gambles. Rabin's arguments strongly depend on expected utility theory, but we show that similar arguments apply to almost all non-expected...

A reasonable level of risk aversion with respect to small gambles leads to a high, and absurd, level of risk aversion with respect to large gambles. This was demonstrated by Rabin for expected utility theory. Later, Safra and Segal extended this result by showing that similar arguments apply to...

Rabin proved that a low level of risk aversion with respect to small gambles leads to a high, and absurd, level of risk aversion with respect to large gambles. Rabin’s arguments strongly depend on expected utility theory, but we show that similar arguments apply to general non-expected utility...

This note shows that Machina's (1982) assumption that preferences over lotteries are smooth has some economic implications. We show that Frâ„chet differentiability implies that preferences represent second order risk aversion (as well as conditional second order risk aversion). This implies,...

This paper extends a New Keynesian model to include roles for currency and depositsas competing sources of liquidity services demanded by households. It showsthat, both qualitatively and quantitatively, the Barnett critique applies: While a Divisiaaggregate of monetary services tracks the true...

This paper demonstrates the extensive scope of an alternative to standardinstrumental variables methods, namely covariate-based methods, for identifying and es-timating effects of interest in general structural systems. As we show, commonly usedeconometric methods, speci…cally parametric,...

We give two new approaches to testing a conditional form of exogeneity. This conditionensures unconfoundedness and identication of eects of interest in structural systems. Asthese approaches do not rely on the absence of causal eects of treatment under the null,they complement earlier methods of...

The high trade costs inferred from gravity are rarely used in thewide class of trade models. Two related problems explain this omis-sion of a key explanatory variable. First, national seller and buyer re-sponses to trade costs depend on their incidence rather than on the fullcost. Second, the...
