This article develops a model that incorporates workers' fair wage preferences into a general equilibrium framework with heterogeneous firms. In a setting where the wage considered to be fair by workers depends on the productivity of the firm they are working in, we study the determinants of profits, involuntary unemployment and within-group wage inequality. We use this model to investigate the effects of globalization, thereby pointing to distributional conflicts that have so far not been accounted for: a simultaneous increase of average profits and involuntary unemployment as well as a surge in within-group wage inequality.

We develop a two-country, multi-sector model of oligopoly in which unionised and nonunionised sectors interact in general equilibrium. The model is used to study the impact of trade liberalisation, deunionisation and firm entry on wages in unionised and non-unionised sectors, and on welfare. We find that a shift from autarky to free trade increases non-union wages and welfare, whereas the effect on union wages is ambiguous. We also show that partial deunionisation leads to higher wages in both unionised and non-unionised sectors, but only increases welfare when the proportion of unionised sectors is sufficiently low. Finally, wages in non-unionised sectors necessarily increase with firm entry, while the response of union wages and welfare depends on the trade regime.

We develop a model of international trade between two symmetric countries that features inter-group inequality between entrepreneurs and workers, and also intra-group inequality within each of those two groups. Individuals in the economy are heterogeneous with respect to their entrepreneurial ability, and firms run by more able entrepreneurs have a higher productivity level and make higher profits. There is rent-sharing at the firm level due to fair wage preferences of workers, and hence firms with higher profits pay higher wages in equilibrium in order to elicit their workers' full effort. We show that in this framework international trade leads to a self-selection of the best firms into export status, and aggregate welfare increases if this selection effect is sufficiently strong. Gains from trade are accompanied by larger inequality along multiple dimensions: Involuntary unemployment and income inequality between entrepreneurs and workers increase, and so does inequality within these two subgroups of individuals, as measured by the respective Gini coefficients.

We show that in the presence of heterogeneous firms the aggregate volume of emissions is influenced not only by the long-established scale effect, but also by a reallocation effect resulting from an increase in the relative size of more productive firms. We show how the relative importance of these effects, and hence the overall effect of trade liberalisation on the environment, is affected by the emission-intensity at the firm level: Aggregate emissions decrease when trade is liberalised if and only if firm-specific emission intensity decreases strongly with increasing firm productivity.

Terms of use: Documents in EconStor may AbstractWe set up a two-country general equilibrium model, in which heterogeneous firms from one country (the source country) can offshore routine tasks to a low-wage host country. The most productive firms self-select into offshoring, and the impact on welfare in the source country can be positive or negative, depending on the share of firms engaged in offshoring. Each firm is run by an entrepreneur, and inequality between entrepreneurs and workers as well as intra-group inequality among entrepreneurs is higher with offshoring than in autarky.All results hold in a model extension with firm-level rent sharing, which results in aggregate unemployment. In this extended model, offshoring furthermore has non-monotonic effects on unemployment and intra-group inequality among workers. The paper also offers a calibration exercise to quantify the effects of offshoring.JEL-Classification: F12, F16, F23

We develop a general equilibrium two-country model with heterogeneous producers, self-selection of only the most productive firms into multinational activity and rent sharing at the firm level due to fairness preferences of workers. In this setting, we identify two major sources of a multinational wage premium. On the one hand, there is a pure composition effect, because multinational firms on average make higher profits, and therefore pay higher wages as well. Since rent sharing relates to a firm's global profits, there is in addition a firm-level wage effect: A multinational firm pays higher wages in its home market than an otherwise identical firm that chooses not to become multinational. We study in detail how these two sources interact in determining the multinational wage premium. In addition, we extend our model to one with technology differences between the two economies and analyse to what extent the multinational wage premium is governed by country-specific factors.
