This paper presents an overview of recent development in the new economic geography (NEG), and discusses possible directions of its future development. Since there already exist several surveys on this topic, we focus on the selected features of the NEG which are important yet have attracted...

This paper presents a new mixing condition for dynamic economies with a Markov structure. The mixing condition is stated in terms of order, and generalizes a number of wellknown conditions used to establish stability of monotone dynamic models. By generalizing the key insights of the original...

This paper studies repeated games with private monitoring where players make optimal decisions with respect to costly monitoring activities, just as they do with respect to stage-game actions. We consider the case where each player can observe other players' current-period actions accurately...

The spatial distribution of industries and population is quite lumpy, and this lumpiness varies across industries. Nevertheless, we show using Japanese data for metropolitan areas that the locations of both industries and population are linked by surprisingly simple and persistent patterns. In...

Migrants from rural to urban areas in dvelopong countries are mostly young workers in their teens and twenties. Earlier migration is rational because migration involves investment in human capital. This study particularly addresses learning own ability. When one's own ability is unknown, larger...

We use the duality in linear programming to solva the problem of optimal partnership contracts with moral hazards. We show the importance of allowing the partners to have partial distribution of revenue under some contingencies. An optimal contract maximizes production efficiency minus the loss...

We consider the dynamic trading strategies that minimize the expected cost of trading a large block of securities over a fixed finite number of periods. We obtain the result in which the institutional investor sells more stocks in early stages when we introduce the conjectures about the others'...

Dutta (J. Econom. Theory, 1991, 55, 64?94) showed that long-run optimality of the limit of discounted optima when the discount rate vanishes is implied by a certain bound on the value function of the optimal program. We introduce a new method to verify this bound using coupling techniques.

We consider the dynamic trading strategies that minimize the expected cost of trading a large block of securities over a fixed finite number of periods and the endogenously determined price impact function that yields the execution prices for individual trades. This analysis is novel in that it...

We present a model of incomplete information games with sets of priors. Upon arrival of private information, each player "updates" by the Bayes rule each of priors in this set to construct the set of posteriors consistent with the arrived piece of information. Then the player uses a possibly...
