Empirical spatial models of trade that are based on a mathematical programming specification often exhibit a large discrepancy between the equilibrium solution and the observed demand, supply and levels of trade flows among countries. This discrepancy may be due to several causes. Assuming,...

In the domain of measuring productivity, the stochastic frontier (SF) model has advanced in leaps and bounds and attracted a large amount of academic attention. Inherently, the model utilises input/output combinations of production units as references to construct a frontier for measuring...

In this paper we study the potential effects of Real-Time Pricing (RTP) of electricity on the need for long-run capacities in the Nordic Power markets. A characteristic of the Nordic Power market is the large variety of production technologies, of which hydro and nuclear power are capacity...

This paper studies the conditions under which an IT revolution may occur and have permanent effects on long-term growth. To this end, we construct a multi-sectoral growth model with endogenous embodied technical progress. The R&D sector expands the range of softwares. The capital sector produces...

Differential equations with advanced and delayed time arguments may arise in the optimality conditions of simple growth models with delays. Models with delayed adoption of new technologies, habit formation or learning-by-using lie in this category. In this paper we present new insight on the...

I propose a simple method to compute the transition process in continuous-time dynamic equilibrium models with occasionally binding inequality constraints. By augmenting the dynamic system with an auxiliary variable standard algorithms are able to solve the extended dynamic system taking the...

This paper develops a model that reproduces the essential aspects of the recent ICT-based economy using the framework of endogenous growth theory in which a central role is played by human capital accumulation. In particular, it considers a multi-sectoral growth model in discrete time with...

This paper develops a model that reproduces the essential characteristics of the recent ICT Revolution and its effects on economic growth using the framework of endogenous growth theory. In particular, it considers a multi-sectoral growth model in discrete time with infinite horizon, endogenous...

Using plant level panel data on Korean manufacturing during the 1990-98 period, this study tries to assess the role of entry and exit in enhancing aggregate productivity, both qualitatively and quantitatively. The main findings of this study are summarised as follows. First, plant entry and exit...

This paper explores the extent to which “zombie” firms – defined as old firms that have persistent problems meeting their interest payments – are stifling labour productivity performance. The results show that the prevalence of and resources sunk in zombie firms have risen since the...
