Using information from all IMF conditionality programs from 1990 to 2018, we implement a dynamic Augmented Inverse Probability Weighting Regression Adjustment approach to examine the effects of programs, including public sector dismissals, on the size of the shadow economy. The estimated effect...

In this paper we use a model of vertical product differentiation to cast doubt on the general validity of the import demand function as specified in macroeconomic models. The empirical importance of our theoretical concerns is then examined with the aid of two hypotheses. According to the first...

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...

In contrast to much recent work regarding the causes of European unemployment, in this paper, we emphasise the importance of capital accumulation. But unlike the few previous studies which have examined the relationship between capital accumulation and unemployment, we argue that what matters...

This paper uses a model of trade in vertically differentiated products to examine the effects of "excessive wage" increases (i.e. above productivity) on the volume of commodity imports. The model predicts that for commodities, in which the country has comparative advantage in high quality...

We analyze some macroeconomic implications that follow from the fact that people tend to consume higher-quality goods as their incomes rise. The model involves two sectors: one producing a homogeneous good and the other producing a product with variable levels of quality. Both sectors use...

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...

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...

The relationship between inequality and redistribution is usually studied under the assumption that the government collects different amounts of taxes from each citizen (voter) but gives back the same amount (in cash or in kind) to everyone. In this paper we consider what happens if the...
