We analyze in this paper the growth and welfare consequences arising from the lack of auditing commitment in a credit market with costly state verification. Specifically, two endogenous growth models, of which one allows lenders to commit to costly auditing strategies to identify borrowers’ investment returns and the other does not, are compared. We show that the inability to commit acts as an ...

This paper provides a unified framework for quantifying the cross-country and cross-sector interactions among trade, innovation, knowledge diffusion. is used to study effect of trade liberalization in an endogenous growth model which comparative advantage stock are determined by innovation The calibrated match observed heterogeneity production, efficiency, spillovers. counterfactual analysis sh...

The convergence features of an Endogenous Growth model with Physical capital, Human Capital and R&D have been studied. We add an erosion effect (supported by empirical evidence) to this model, and fully characterize its convergence properties. The dynamics is described by a fourth-order system of differential equations. We show that the model converges along a one-dimensional stable manifold an...

We examine whether the Phelps–Koopmans theorem is valid in models with nonconvex production technologies. We argue that a nonstationary path that converges to a capital stock above the smallest golden rule may indeed be efficient. This finding has the important implication that “capital overaccumulation” need not always imply inefficiency. Under mild regularity and smoothness assumptions, we pr...

In this paper we analyze how the tax compliance policy affects the rate of economic growth. We consider a model of overlapping generations in which the paths of all the macroeconomic variables are endogenously determined and we perform the comparative statics analysis of changes in both the probability of inspection and the penalty fee imposed on tax evaders. We also show the nonoptimality from...

This paper concludes the study of transition paths in the continuous-time recombinant endogenous growth model by providing numerical methods to estimate the threshold initial value of capital (a Skiba-type point) above which the economy takes off toward sustained growth in the long run, while it is doomed to stagnation otherwise. The model is based on the setting first introduced by Tsur and Ze...

We extend the basic Schumpeterian endogenous growth model by allowing incumbents to undertake innovations to improve their products, while entrants engage in more “radical” innovations to replace incumbents. Our model provides a tractable framework for the analysis of growth driven by both entry of new firms and productivity improvements by continuing firms. The model generates a non-degenerate...

Past experiences and social forces have been incorporated into tastes in order to analyze various microeconomic issues. We use these “extended preferences” to model the making of standard-of-living aspirations and study their effect on macroeconomic variables. We concentrate first on consumption behavior when there is habit formation. Such behavior is in accordance with several empirical facts ...

This paper presents an endogenous growth model in which some firms devote resources to developing higher quality products (innovative R&D) and other firms devote resources to copying these products (imitative R&D). Although consumers benefit from the knowledge created by both types of R&D activities, only innovative R&D subsidies lead to faster economic growth and imitative R&D subsidies actual...

Empirical attempts to measure the speed of convergence -the rate at which a country's per capita income approaches its steady state relative to its distance from its steady state -have started from the assumption that it is constant. In contrast, neoclassical models of capital accumulation usually predict that the speed of convergence decreases as income approaches its steady state. Estimating ...
