With the exception of existence, not much seems to be known of economies where individual preferences are affected by prices. We show that the main properties of competitive equilibria that fall under the general heading of qualitative comparative statics remain true when preferences are price dependent, provided that the total resources are allowed to vary in the parameter space. The equilibri...

We examine pure no-load funds over a 5-year period. For equity funds, trading activity is negatively related to returns. Expense ratios are not significantly related to returns. Potential capital gains exposure and tax cost ratio are positively related to return. For fixed income funds, trading activity is positively related to return. Expense ratios and tax cost ratios are negatively related t...

For economies with a fixed finite set of traders, few results characterize Walrasian equilibria by their social choice properties. Pareto efficient allocations typically require lump-sum transfers. Other characterizations based on the core or strategyproofness apply only when, as in continuum economies, agents cannot influence prices strategically. Or the results concern social choice with a va...

Our work has been concerned with the numerical simulation of dynamic economies with heterogeneous agents and economic distortions. Recent research has drawn attention to inherent difficulties in the computation of competitive equilibria for these economies: A continuous Markovian solution may fail to exist, and some commonly used numerical algorithms may not deliver accurate approximations. We ...

Capitalizing on the most recent worldwide estimates of the impacts of climate change on agricultural production, this paper assesses the economic effects of climate change for Southeast Asian countries through 2080. The results suggest that the aggregate impacts of agricultural damages caused by climate change on the global economy are moderate. However, the uneven distribution of productivity ...

This paper explains why domestic debt composition in some emerging economies is risky. To this end, it carries out a systematic analysis of the determinants of the socalled domestic original sin, which refers to the inability of emerging economies to borrow domestically in local currency, at long maturities and fixed interest rates. The paper builds on a large dataset compiled by the authors fr...

We analyze an exchange economy of unsecured credit where borrowers have the option to declare bankruptcy in which case they are temporarily excluded from financial markets. Endogenous credit limits are imposed that are just tight enough to prevent default. Economies with temporary exclusion differ from their permanent exclusion counterparts in two important properties. If households are extreme...

This paper analyzes the impact of investment in information technology (IT) on the recent resurgence of world economic growth. We describe the growth of the world economy, seven regions, and 14 major economies during the period 1989–2004. We allocate the growth of world output between input growth and productivity and find, surprisingly, that input growth greatly predominates! Moreover, differe...

In a two-country infinite-horizon model, with two traded goods and two factors of production and no international borrowing and lending, there is no convergence of incomes if there is factor-price equalization. With factor-price equalization, the Euler equations of the two economies become identical. I show that in such a set-up if agents have a non-zero probability of death, then we do get con...

With the exception of existence, not much is known of economies where individual preferences may depend on prices. We show that the main properties of competitive equilibria that fall under the general heading of qualitative comparative statics remain true when preferences are price dependent, provided that the total resources are allowed to vary in the parameter space. The equilibrium set is a...
