Using an intertemporal model of saving and capital accumulation with two types of agents (workers and capitalists) we demonstrate that it is impossible for any binding minimum wage to increase the after-tax incomes of workers if the production function is Cobb-Douglas with constant returns to...

This paper analyzes the impact of demographic aging on capital accumulation and welfare in economies with unfunded pensions. Using a two-period overlapping generation model with potentially endogenous retirement decisions, it shows that both the type of aging, i.e. declining fertility or...

This paper develops a model with multiple market locations in which the quality of intangible assets of firms, provided by management, determines the firms. performance. Despite an ex ante symmetry of potential entrants, the equilibrium assignment of heterogeneous managerial skills to firms...

Two macro models one for a closed economy and the other for a small open economy are used to examine the scope for income redistribution and employment creation. In particular, the introduction of both a guaranteed annual income (basic income) and an employment subsidy are examined, and these...

This paper develops a quality-ladder model of endogenous growth to study the interplay between in-house R&D and marketing expenditure. Although promotional activity is modelled as purely wasteful competition among firms for attention, it unambiguously fosters innovation activity of firms, and...

A positive relationship between firm size and product diversification is a long-standing stylized fact. However, so far there is no appropriate theoretical model to explain the underlying forces of this observation. This paper analyzes an oligopoly model with asymmetric multiproduct frms, which...

It is often argued that implicit taxation on continued activity of elderly workers is responsible for the widely observed trend towards early retirement. In a world of laissez-faire or of first-best efficiency, there would be no such implicit taxation. The point of this paper is that when...

In this paper we argue that strong political economy forces explain the rush of the EU to expand eastwards. We use a model of vertical product differentiation in order to claim that technologically- advanced EU firms (residing in high-income member countries) prefer a mutual market-opening with...

We construct a two sector general equilibrium model in which one sector produces a homogeneous good and the other sector produces a vertically differentiated good. We demonstrate that uniform (across sectors) and (Hicks) neutral technological change can cause an increase in the skill premium.

This paper evaluates two approaches to work-sharing by examining both within the same macro model. The standard approach involves imposing a quantity constraint on labour market participants (a maximum number of standard hours for each worker). This approach is compared to a revenue-neutral...
