This paper corrects the analysis, presented in Albert and Meckl (1991), of adjustment in a dynamic specific-factors model with endogenous capital stocks, and extends it to a multi-sector setup.

This paper generalizes the analysis in Albert (1989) and Meckl (1990) of adjustment in a dynamic specific-factors model with endogenous capital stocks. Capital reallocation and accumulation are consequences of investment decisions and depreciation. The Investment process is analyzed under a...

The paper considers intersectoral capital mobility in the context of investment theory. Convex costs of adjustment explain imperfect mobility of capital between sectors. Stocks of capital are endogenous; the model essentially is a twosector growth model with Keynesian investment functions. The...

The paper proves a theorem on modified Kuhn-Tucker conditions for the case where a linearly homogenous function is part of the target function. These conditions are necessary and sufficient if target function and constraints satisfy certain re-quirements. Moreover, the envelope theorem can be...

The paper incorporates the efficiency-wage theory into an otherwise standard trade model. The model accounts for sector-specific job rents and involuntary unemployment while preserving decisive properties of the competitive fullemployment approach. The key results from the literature can be...

We investigate how joint production affects the likelihood of factor price equalization (FPE) through trade. Following up on recent contributions by Samuelson (1992) and Jones (1992), we propose to take the relative size of the FPE region of endowment distributions to measure this likelihood. We...

If we take it that, at least in the social sciences, "realistic" implies "finite", then countless economic models involving infinitary assumptions must obviously be classified as unrealistic - for example, models with infinitely divisible goods, a continuum of traders, consumers optimizing over...

The double-dividend argument (as used in political debates) addresses worries that a green tax may lead to higher unemployment when wages are inflexible. As protection against this possibility, it is proposed to use the proceeds of the green tax to subsidize employment. In the best case, this...

The paper proves that the Bayesian approach to learning and expectations formation implies no propositions that could conceivably be refuted by observation. For a (non-expanding) universe infinite in time but finite at any point of time, it is shown that by a suitable choice of priors, any...
