How does market organization affect quality innovation efforts and social welfare? Three stochastic dynamic market structures considered are monopoly, duopoly, and social planning. Products can be either linearly or nonlinearly substitutable. The introduction of a step function allows richer...

A neoclassical factor demand model for structures, equipment and labour is analyzed. It incorporates a variety of dynamic specifications, such as a multi-period time-to-build for structures, internal adjustment costs for each production factor, and external investment adjustment costs....

This paper provides evidence for a particular channel through which sustained terrorism in rural areas may affect growth in developing countries. Using micro-level data from agricultural surveys during the period of insurgency in Punjab (India), I find significant negative effects of terrorism...

Presented is an evolutionary model of consumer non-durable markets, which is an extension of a previously published paper on consumer durables. The model suggests that the repurchase process is governed by preferential growth. Applying statistical methods it can be shown that in a competitive...

We study the optimal hiring and firing decisions of a firm under two different firing costs regulations: 1) Dual labor markets characterized by high firing costs for workers with seniority above a threshold ("permanent workers") and by low costs for "temporary workers". 2) The Single Labor...

Typically, firms change their size through a row of discrete leaps over time. Sunk costs, regulatory, financial and organizational constraints, talent distribution and other factors may explain this fact. However, firms tend to grow or fall discontinuously even if those inertial factors were...

Typically, firms change their size through a row of discrete leaps over time. A very basic model allowing for discontinuous growth can be based on a couple of assumptions: (a) in the short run, the firm’s equipment and organization provide the maximum profit only for a given production level,...

How does market structure affect quality innovation efforts and social welfare? This study considers three allocation mechanisms in a model of dynamic quality innovation: monopoly, duopoly, and the social planner. In this model, quality advances depend upon a stock of accumulated know-how,...

The timing of investment and capital stock accumulation can differ as a result of time-to-build or delivery lags. In this study calibration methods are used to illustrate the difference in these sources of gestation lags.

This paper is concerned with the role of debt composition on the firm-level investment by raising a main question: whether firms with high foreign currency or short maturity debts have less investment following a financial crisis. This paper finds that firms with more dollar debt have...
