This paper considers an on-the-job search model that includes wage bargaining and employer-employee mismatch. There are two states of workers in relationship to their fit for a particular job, good match versus bad match (mismatch). These states change in accordance with a stochastic process....

This paper explores an optimal personnel organization problem of monetary policy committees. First, I construct an analytically tractable model for monetary policy analysis which starts from decision-making in the monetary policy committee. Using the model, I investigate the relationship between...

This paper develops an overlapping generations model that involves the endogenous determination of fertility and an explicit city structure in order to analyze fully the social and natural changes in city populations. We provide conditions under which the model exhibits the spatial features of...

This paper develops a model where income inequality and intergenerational mo- bility are jointly determined via redistributive politics. The model includes two key factors: accessibility of tertiary education for poor-born agents and multiple self- ful?lling expectations of agents. Given these...

Using a directed search model, modified from random matching, this paper investigates how trading frictions in asset markets affect portfolio choices, asset prices, and welfare. By solving the model numerically, it is demonstrated that the asset price increases (decreases) in the matching...

This paper presents an examination of the relation between pre-trade transparency and market quality in the Tokyo Stock Exchange (TSE). Mixed evidence related to this relation has been reported worldwide. We analyzed this relation using a discrete change of disclosure policy in the 2000s. A...

This paper introduces an overlapping-generations model with earnings hetero- geneity and borrowing constraints. The labor income tax and the allocation of tax revenue across social security and forward intergenerational public goods are determined in a bidimensional majoritarian voting game...

This paper analyzes the market diffusion of a new product whose quality is uncertain. Consumers learn the product quality by observing the history of market outcomes. Firms cannot observe how consumers evaluate the product quality; instead, they learn by observing consumer behavior. New entry...

This paper constructs a North-South quality-ladder model in which foreign direct investment (FDI) is determined by the endogenous location choice of firms, and examines analytically how strengthening patent protection in the South affects welfare in the South. Strengthening patent protection...

The objective of this paper is to examine effects of realized covariance matrix estimators based on intraday returns on large-scale minimum-variance equity portfolio optimization. We empirically assess out-of-sample performance of portfolios with different covariance matrix estimators: the...
