Creator: Rivera-Batiz, Luis. and Romer, Paul Michael, 1955- Series: Modeling North American economic integration Abstract:
In a world with two similar, developed economies, economic integration can cause a permanent increase in the worldwide rate of growth. Starting from a position of isolations, closer integration can be achieved by increasing trade in goods or by increasing flows of ideas. We consider two models with different specifications of the research and development sector that is the source of growth. Either form of integration can increase the long-run rate of growth if it encourages the worldwide exploitation of increasing returns to scale in the research and development sector.

Creator: Benhabib, Jess, 1948- and Rustichini, Aldo. Series: Economic growth and development Abstract:
In this paper we study the relationship between wealth, income distribution and growth in a game-theoretic context in which property rights are not completely enforcable. We consider equilibrium paths of accumulation which yield players utilities that are at least as high as those that they could obtain by appropriating higher consumption at the present and suffering retaliation later on. We focus on those subgame perfect equilibria which are constrained Pareto-efficient (second best). In this set of equilibria we study how the level of wealth affects growth. In particular we consider cases which produce classical traps (with standard concave technologies): growth may not be possible from low levels of wealth because of incentive constraints while policies (sometimes even first-best policies) that lead to growth are sustainable as equilibria from high levels of wealth. We also study cases which we classify as the "Mancur Olson" type: first best policies are used at low levels of wealth along these constrained Pareto efficient equilibria, but first best policies are not sustainable at higher levels of wealth where growth slows down. We also consider the unequal weighting of players to ace the subgame perfect equiliria on the constrained Pareto frontier. We explore the relation between sustainable growth rates and the level of inequality in the distribution of income.

Creator: Chang, Roberto. Series: Conference on economics and politics Abstract:
This paper examines the determination of the rate of growth in an economy in which two political parties, each representing a different social class, negotiate the magnitude and allocation of taxes. Taxes may increase growth if they finance public services, but reduce growth when used to redistribute income between classes. The different social classes have different preferences about growth and redistribution. The resulting conflict is resolved through the tax negotiations between the political parties. I use the model to obtain empirical predictions and policy lessons about the relationship between economic growth and income inequality. In particular, I show that, although differences in growth rates across countries may be negatively related to income inequality, redistributing wealth does not enhance growth.

Creator: Kahn, James A. (James Allan) and Lim, Jong-Soo. Series: Conference on economics and politics Abstract:
This paper analyzes the political economy of growth as an issue of intergenerational distribution. The first part of the paper develops a model of endogenous growth via human capital accumulation in an overlapping generations setting. Equilibrium growth is inefficient due to the presence of an intergenerational externality. We characterize the set of Pareto efficient paths for physical and human capital accumulation, and find that there is a continuum of efficient growth rate-interest rate combinations. The preferred combination for an infinitely-lived planner will depend on the social discount rate. Competitive equilibrium with subsidized or mandated human capital accumulation may give rise to a Pareto efficient steady state, though for some parameters efficiency requires some intergenerational redistribution. We then argue that a social planner or government with an infinite horizon is incongruous in an OG model when the agents all have finite horizons. Hence the second part of the paper addresses the question of how a government whose decisionmakers reflect the finite horizons of their constituents would choose policies that affect physical and human capital accumulation. Specifically we assume that each government maximizes a weighted sum of utilities of those currently alive. Each period the government selects a policy that takes into account the effect (through state variables) on subsequent policy decisions (and hence on the welfare of the current young generation). Numerical methods involving polynomial approximations are used to compute equilibria under specific parametric assumptions. Equilibrium growth rates turn out to be substantially below efficient rates.

Creator: Bertola, Giuseppe. Series: Economic growth and development Abstract:
This paper proposes a model of diversifiable uncertainty, irreversible investment decisions, and endogenous growth. The detailed microeconomic structure of the model makes it possible to study the. general equilibrium effects of obstacles to labor mobility, due to institutional as well as technological features of the economy. Labor mobility costs reduce private returns to investment, and the resulting slower rate of endogenous growth unambiguously lowers a representative individual's welfare. Turnover costs can have positive effects on full employment equilibrium wages when all external effects are disregarded: this may help explain why policy and institutions often tend to decrease labor mobility in reality, rather than to enhance it. Lower flexibility, however, reduces the growth rate of wages in endogenous growth equilibrium, with negative welfare effects even for agents who own only labor.

Creator: Segerstrom, Paul Stephen, 1957- Series: Economic growth and development Abstract:
This paper develops a dynamic general equilibrium model of economic growth. The model has a steady state equilibrium in which some firms devote resources to discovering qualitatively improved products and other firms devote resources to copying these products. Rates of both innovation and imitation are endogenously determined based on the outcomes of R&D races between firms. Innovation subsidies are shown to unambiguously promote economic growth. Welfare is only enhanced however if the steady state intensity of innovative effort exceeds a critical level.

Creator: Parente, Stephen L. and Prescott, Edward C. Series: Economic growth and development Abstract:
Technology change is modeled as the result of decisions of individuals and groups of individuals to adopt more advanced technologies. The structure is calibrated to the U.S. and postwar Japan growth experiences. Using this calibrated structure we explore how large the disparity in the effective tax rates on the returns to adopting technologies must be to account for the huge observed disparity in per capita income across countries. We find that this disparity is not implausibly large.

Creator: Laitner, John. Series: Productivity and the industrial revolution Abstract:
This paper presents a model in which a country's average propensity to save tends to rise endogenously over time. The paper uses a two-sector neoclassical framework to model the transition from agriculture to manufacturing which typically accompanies economic development. Key assumptions are that only the agricultural sector uses land and a simple version of Engel's law. When a country's income per capita is low, agricultural consumption is important; consequently, land is valuable and capital gains on it may account for most wealth accumulation, making the NIPA APS appear low. If exogenous technological progress raises incomes over time, Engel's law shifts demand to manufactured goods. Then land's importance in portfolios relative to reproducible capital diminishes and the measured average propensity to save can rise.
