This paper investigates the impact of lumpy capital adjustment on productivity at the firm level using data on Japanese manufacturing industries. We estimate stochastic production frontiers, taking firm heterogeneity into account. We find that investment spikes are negatively related to...

The conjecture of a price-induced technical progress was formulated by Hicks in 1932. It acquired prominence during the seventies with the work of Hayami and Ruttan who dealt with the agricultural sectors in the United States and Japan. A novel specification of this hypothesis is that output and...

In this paper I consider the 1991 Grossman-Helpman model which analyses the role of innovation on growth. The model assumes constant returns to scale. I intend to show what happen in this model if I assume strong increasing returns. In particular, under the assumption of increasing returns of...

We show that Stiglitz's (1974) principal-agency theory of share tenancy does not imply, as alleged, that the optimal tenant share is less than one for risk-averse tenants nor that the share decreases monotonically with tenant risk aversion. Tenants may self insure by working harder increasingly...

We examine the pattern of information technology (IT) capital adjustment using data from U.S. industries. Using the gap between actual and desired IT capital stocks, we estimate the shape of the adjustment cost function in IT investment. Both ordinary least squares and nonparametric regression...

Assuming that there exists a preference for luxury goods and a knowledge spillover from luxury goods production to goods production, this paper constructs an endogenous economic growth model. The model predicts two steady states: one is a steady positive growth state with regard to luxury goods...

Hansen and Lønstrup [Journal of Population Economics, 2012] construct a three-period, life-cycle model to study the famed Ben-Porath mechanism and attempt to reconcile it with the empirical findings in Hazan [Econometrica, 2009]:increased life expectancy has a positive effect on schooling but a...

This paper considers an overlapping generations model of a household economy in an agrarian set up to examine the short run as well as long run effects of increase in size of land holding on child labour, human capital formation and growth. It is assumed that each household consists of one adult...
