The welfare gain to consumers from the introduction of personal computers is estimated here. A simple model of consumer demand is formulated that uses a slightly modified version of standard preferences. The modification permits marginal utility, and hence total utility, to be finite when the...

This paper analyzes the decentralization of decision-making in aid-giving in a theoretical rent-seeking framework. In this analysis the root donor establishes a necessary criterion for potential recipients: good governance. The potential recipients compete in hierarchal contests for funds. The...

We argue that a purpose of foreign aid is to whet the appetite of the recipient in order to bring about a long term commitment to what the donor perceives as a need, but which the recipient may rank lower down on his list of undertakings, or may be sufficiently resource constrained as to be...

Patience affects economic growth, no news. This paper investigates the opposite causal relationship, i.e., how growth influences patience. We propose a simple theoretical framework where heterogeneous parents may choose to transmit their cultural trait - patience - to their offspring. Our model...

This paper studies an analytically tractable model of the formation and evolution of chains of production. Over time, entrepreneurs accumulate techniques to produce their good using goods produced by other entrepreneurs and labor as inputs. The value of a technique depends on both the...

We develop a general equilibrium model to assess the quantitative impact of distorting institutions and policies related to the poor business environment in 30 sub-Saharan African countries. A subset of the distortions - namely, regulation, crime, corruption, and poor infrastructure - is modeled...

We analyze how adding the shadow economy to official output figures affects technical efficiency. We find that this only slightly affects the ranking of efficiency scores, but increases average efficiency. Our results are robust to the functional form of the production technology and the...

We offer a duality-based methodology for incorporating multi-sector effects of international trade into open economy macroeconomic models, developing the concepts of the dynamic factor price equalization set and the integrated intertemporal equilibrium. Under this approach, the aggregate...

I develop a method to measure and separate the production misallocation caused by failures in factor markets versus financial markets. When I apply the method to rice farming villages in Thailand I find surprisingly little misallocation. Optimal reallocation would increase output in most...

This paper evaluates the global welfare impact of China's trade integration and technological change in a quantitative Ricardian-Heckscher-Ohlin model implemented on 75 countries. We simulate two alternative productivity growth scenarios: a balanced one in which China's productivity grows at the...
