FISCAL POLICY IN AN ENDOGENOUS GROWTH MODEL WITH PUBLIC CAPITAL AND POLLUTION

This paper studies the growth and welfare effects of fiscal policy in an endogenous growth model with public capital and environmental pollution. I assume that pollution is due to aggregate production, and that it does not have a direct effect on production but only reduces household utility. I study the growth effects of fiscal policy for the model on the balanced growth path, taking transition dynamics into account. I then analyse the welfare effects of fiscal policy along the balanced growth path. Finally, I show how the fiscal parameters must be set so that the competitive economy replicates the social optimum.     

A ONE-SECTOR NEOCLASSICAL GROWTH MODEL WITH ENDOGENOUS RETIREMENT

This paper extends Diamond's overlapping generations model by allowing the agents to make the retirement decision. Earning a higher wage income when young not only enables the agents to save more. It also induces more agents to retire early and gives an additional incentive to save more for retirement. This leads to a higher capital–labour ratio in the following period and hence the next generation of agents earns a higher wage income when young. Due to this positive feedback mechanism, endogenous retirement magnifies the persistence of growth dynamics and even generates multiple steady-states for empirically plausible parameter values.     

A SAVINGS SUBSIDISATION SYSTEM IN A MODEL OF ENDOGENOUS FERTILITY AND ENDOGENOUS GROWTH: AN EXTENSION OF WIGGER (1999)

Population ageing is now an established demographic characteristic of many economies. Economists working in the endogenous growth theory tradition have sought to model the relationship between public pensions, financed on a 'Pay-As-You-Go' basis, and the growth in per capita incomes. The resultant intergenerational wealth redistribution from young to older people seems to decrease private savings, diminish capital accumulation, and lower the growth of per capita incomes. The underlying transmission mechanism appears to be a crowding out effect in private capital markets contingent upon the introduction of public pension systems. A growing literature exists on the interrelationships between public pension schemes, fertility rates and endogenous growth. Following Wigger's (1999) pioneering overlapping generations endogenous growth model, we extend this model to examine the effects of a savings subsidisation system on the rate of per capita income growth, fertility and voluntary intrafamily wealth transfers, where parents view children both as an insurance good and a consumption good. Moreover, children care about the consumption levels of their parents. An increase in contributions to a savings subsidised public pension scheme will crowd out private intergenerational transfers from the young to the old and thereby negate the usefulness of children as an insurance good.     

UNEMPLOYMENT IN AN EQUILIBRIUM MODEL WITH BARGAINING*

This paper develops a model which embeds the Nash-equilibrium version of McDonald and Solow's (1981) wage-bargaining model into an otherwise standard static equilibrium macro model. Equilibrium unemployment is possible. Real shocks to demand result in pro-cyclical employment and anti-cyclical real wage movements while money shocks are neutral. This is in some contrast to the results obtained by McDonald and Solow.     

SOCIAL STATUS,EDUCATION AND GOVERNMENT SPENDING IN A TWO‐SECTOR MODEL OF ENDOGENOUS GROWTH*

This paper extends the relative wealth specification of status preference to the two‐sector Uzawa (1965 )– Lucas (1988 ) model and examines the effectiveness of government spending on economic growth. It is found that the desire for relative wealth‐induced social status and/or the education component of relative wealth‐induced social status are important ingredients in determining the growth rate effects of government spending. Provided that the agent is concerned with his or her relative social position, the education‐induced social status plays a more important role than the physical‐asset‐induced social status in determining the validity of public spending on growth. If individuals do not care about their education‐driven social rewards, then an increase in government spending has no effect on the balanced growth rate regardless of the presence of the physical‐asset‐induced social status. A rise in government spending reduces the long‐run growth rate if the education‐induced social status is present.     

A MATCHING MODEL WITH ENDOGENOUS SKILL REQUIREMENTS>*

We consider a labor market in which workers differ in their abilities and jobs differ in their skill requirements. The distribution of worker abilities is exogenous, but we model the choice of skill requirements by firms. High‐skill jobs produce more output than low‐skill jobs, but high‐skill jobs require high‐skill workers and thus are more difficult to fill. We use a matching model together with a Nash bargaining approach to wage setting to determine the equilibrium mix of job types, along with the equilibrium relationship between worker and job characteristics, wages, and unemployment.     

ENDOGENOUS PUNISHMENTS IN AGENCY WITH VERIFIABLE EX POST INFORMATION*

The article studies an adverse selection model in which a contractible, imperfect signal on the agent's type is revealed ex post. The agent is wealth constrained, which implies that the maximum penalty depends on the contracted transaction (e.g., the volume of trade). First, we show that the qualitative effects of the signal can be unambiguously tied to the nature of the problem (e.g., whether the agent is in a “buyer” or a “seller” position). Second, the distortions caused by informational asymmetries may become more severe although more information is now available. Finally, the signal can actually serve to increase the agent's informational rents.

COMPETITIVE GROWTH IN A LIFE‐CYCLE MODEL: EXISTENCE AND DYNAMICS*

The dynamic behavior of the capital growth rate is analyzed using an overlapping‐generations model with continuous trading. Assuming a technology satisfying constant social returns to capital, the equilibrium growth rate is piecewise‐defined by functional differential equations with both delayed and advanced terms. The main result concerns the existence of a solution expressed as a series of exponentials, which is shown to crucially depend on the initial wealth distribution among cohorts. Upon existence, the dynamics of the capital growth rate has a saddle‐point trajectory that converges to a unique steady state. Along the transition path, the growth rate exhibits exponentially decreasing oscillations.     

TARIFF POLICY AND WELFARE IN AN INTERNATIONAL DUOPOLY WITH CONSUMER‐FRIENDLY INITIATIVE

The purpose of this paper is to explore how strategic tariff policy and welfare are affected by the consumer‐friendly initiative of foreign exporting firms. We define a firm that is consumer‐friendly or non‐profit‐based if it considers both its own profit and consumer surplus. This paper extends Brander and Spencer by taking the consideration of consumer‐friendly firms into an international duopoly, and within such context examining the tariff policy and welfare. The consumer‐friendly initiative that leads to trade liberalization is a ‘Win‐Win‐Win’ solution in the sense that it is not only beneficial for foreign exporting firms, but also for the government and consumers of the importing country.     

EQUILIBRIUM GROWTH IN A MONETARY ECONOMY WITH TRANSACTIONS COSTS*

The paper describes a dynamic general equilibrium monetary economy with technological primitives that are consistent with the possibility of asymptotic equilibrium growth. The paper focuses on the relationship between equilibrium financing constraints on investment goods, transaction costs and economic growth. A generalized growth condition is derived that involves both monetary growth rates and transaction costs. The condition is used to show that (i) although inflation taxes can potentially exert a negative influence on long-run economic growth, these growth effects cannot in general be arbitrarily large; and (ii) for some monetary growth rates, money is superneutral in contrast to the models of Stockman and Abel. Numerical work indicates that although the welfare and growth effects of decreasing nominal interest rates from a benchmark are large, the costs associated with raising nominal interest rates from benchmark are not.     

STRATEGIC EQUILIBRIA IN A MODEL OF ECONOMIC GROWTH WITH INPUT INTERDEPENDENCE

Two countries face a strategic interdependence in producing intermediate goods. Producing these intermediate goods requires both domestic capital and another imported intermediate good. Individually, both economies determine a balanced growth path by taking into account this interdependence in different grades of awareness. By allowing for strategic interactions in the analysis, we adapted a two‐agent dynamic setting and find an interior Markov perfect equilibrium as well as an open‐loop equilibrium reflecting these different degrees of reaction. We find that main results resemble each other but growth rates will be higher when strategies are dynamically updated.     

THE POLITICAL ECONOMY OF QUOTA RENTS IN A DYNAMIC INTERNATIONAL TRADE MODEL*

This paper considers the implications of allowing quota rents to become capitalized. Capitalized quota rents crowd out physical capital in savers’portfolios, reducing the capital stock. Capitalization of quota rents also makes removal of the quota politically more difficult, since those currently alive may not be able to fully compensate the losers before the losers die. I use an overlapping generations model to provide examples which illustrate the difficulty of removing a quota once its rents have been fully capitalized. This work has implications for any policy which could lead to capitalized rents.
