This paper constructs a tractable model of endogenous growth with financial frictions and firm heterogeneity. We introduce factor income tax, consumption tax as well as the government consumption into the base model and explore the growth effect of fiscal policy. We show that from the qualitative perspective, the long-run effects of fiscal actions in our model are similar to those obtained in the representative-agent models. However, the quantitative impacts of fiscal policy on long-run growth in our setting can be substantially different from those established in the model where agents are homogeneous and there is no financial friction.
This paper explores the role of consumption externalities in a neoclassical growth model in which households have heterogeneous preferences. We find that a higher degree of average conformism accelerates the convergence speed of the economy towards the steady state as in the case of homogeneous conformism. Furthermore, we reveal that the wealth inequality expands or shrinks in the case of heterogeneous conformism, while it does not expand but shrinks in the case of homogeneous conformism.
The objective of this study is to design a laboratory experiment to explore the effect of ambiguity on a subject’s search behavior in a finite-horizon sequential search model. In so doing, we employ a strategy to observe the potential trend of reservation points that is usually unobserved. We observe that subjects behaving consistently across treatments reduce their reservation points in the face of ambiguity over point distribution. Our result is consistent with the theoretical implication obtained by Nishimura and Ozaki (Journal of Economic Theory 2004).
This paper constructs a simple model of endogenous growth with financial frictions and firm heterogeneity. In the presence of financial constraints and heterogeneity in production efficiency of firms, the firms whose efficiency exceeds the cutoff level produce and the entrepreneurs who own those firms become borrowers. We show that even if production technology of each firm has an Ak property, the aggregate economy has transition dynamics and that the balanced growth rate depends on the aggregate distribution of wealth between rentiers and entrepreneurs.
Using a simple framework of Cooper and John (1988) and Cooper (1999), this paper derives the conditions under which overconfidence and underconfidence of agents lead to Pareto improvement. We show that an agent’s overconfidence in a game exhibiting strategic complementarity and positive spillovers and an agent’s underconfidence in a game exhibiting strategic complementarity and negative spillovers can lead to Pareto improvement.
Credit market imperfections typically characterize a low quality financial market, where the quality of information about borrowers is low and/or enforcement rules or institutions are not well developed. We consider an economy with credit market imperfections and analyze how changes in the degree of credit constraints affect economic fluctuations. The analysis demonstrates that if the degree of credit market imperfection is either severe or too soft, the economy converges to an asymptotically stable steady state, whereas if the degree of imperfection is moderate, the equilibrium involves deterministic cycles or chaos.
This paper explores the role of consumption externalities in a neoclassical growth model in which households have heterogeneous preferences. We find that the degree of conformism in consumption held by each household significantly affects the speed of convergence of the aggregate economy as well as the patterns of wealth distribution in the steady state equilibrium. In particular, a higher degree of consumption conformism accelerates the convergence speed of the economy towards the steady state. We also reveal that in an economy with a high degree of conformism, the pattern of initial distribution of wealth tends not to be sustained in the long run.
This paper explores the relation between capital accumulation and transformation of industrial structure in a small open-economy. Using a three-sector, neoclassical growth model with non-homothetic preferences, we examine dynamic behavior of the small country in the alternative trade regimes. We show that capital accumulation plays a leading role in the process of structural transformation. It is also revealed that the trade pattern significantly affects structural change. We demonstrate that our model can mimic a typical pattern of change in industrial structure that has been observed in many developed economies.
