In this article we design an econometric test for monotone comparative statics (MCS) often found in models with multiple equilibria. Our test exploits the observable implications of the MCS prediction: that the extreme (high and low) conditiona l quantiles of the dependent variable increase monotonically with the explanatory variable. The main contribution of the article is to derive a likelihood-ratio test, which to the best of our knowledge is the first econometric test of MCS proposed in the literature. The test is an asymptotic “chi-bar squared” test for order restrictions on intermediate conditional quantiles. The key features of our approach are: (1) we do not need to estimate the underlying nonparametric model relating the dependent and explanatory variables to the latent disturbances; (2) we make few assumptions on the cardinality, location, or probabilities over equilibria. In particular, one can implement our test without assuming an equilibrium selection rule.

In Theory of Moral Sentiments, Adam Smith reasons about how a change in one thing, A, is attended by a change in another thing, B. In expounding on such bivariate relationships, Smith sometimes seems to go out of his way to posit a state of the world in which the relationship would break down. That feature suggests an irony about knowing how a change in B attends a change in A. We might think we understand the bivariate relationship, but it holds only for certain states of the world. The relationship is circumstanced. The more one studies the Moral Sentiments, the more one realizes that circumstantiality suffuses its teachings. My discussion arrives at a place of doubt about the most important bivariate relationship – that between approval from our conscience and doing good. Smith seems to suggest, particularly at the end of his life, that a person can best know the relationship between his conscience’s approval and his doing good under circumstances of his having frank and open friendships. The implication for politics is that we want that kind of government that best conduces to frank and open friendships.

A number of earlier studies have examined whether extensive labour market programmes (ALMPs) contribute to upward wage pressure in the Swedish economy. Most studies on aggregate data have concluded that they actually do. In this paper we look at this issue using more recent data to check whether the extreme conditions in the Swedish labour market in the 1990s and the concomitant high levels of ALMP participation have brought about a change in the previously observed patterns. We also look at the issue using three different estimation methods to check the robustness of the results. Our main finding is that, according to most estimates, ALMPs do not seem to contribute significantly to an increased wage pressure.

When the factor endowments of two trading countries do not lie in the same diversification cone, trade in commodities may not reduce the international factor return differentials. This chapter specifies some conditions of the demand function in a two-factor, infinite-good model that guarantee partial factor price equalization. The wage-rental ratios of two trading countries are convergent if goods farther apart are poorer substitutes than goods closer together in the factor-intensity ranking. This generalizes the result in the literature, which is usually obtained under the assumption of Cobb–Douglas utility and production functions.

The logic of economic inquiry requires two distinct research programs. One program treats economic life in terms of invariant formal categories across time and place. The other program treats the continual generation of novelty and turbulence through time and human interaction. These programs are not commensurable: one cannot be reduced to the other. The former program must be conveyed by a theory of equilibrium; the latter program requires a process-based theory of emergent phenomena. Roy Weintraub articulated a neo-Walrasian research program in his General Equilibrium Analysis, and here I sketch a complementary neo-Mengerian program. In presenting this sketch, I also explain that needless analytical confusion and antagonism can result from a failure to recognize that economic analysis requires two distinct research programs. As a historical side-bar, Carl Menger probably recognized this situation, as evidenced by his correspondence with Léon Walras.

We extend the Jones (1971) analysis of the effects of distortions in 2×2 trade models to the case of a two-sector dynamic general equilibrium model of a small open economy with capital accumulation. We do a comparative steady state analysis for the effect of policy changes on factor prices and the capital stock, and examine the dynamics of the system in the neighborhood of the steady state. We also show that the system will have multiple equilibria when value and physical factor intensity rankings of the sectors do not agree.

This chapter explores various aspects of mergers and acquisitions in the banking industry within a simple model that allows explicit comparison of sector performance before and after the mergers and acquisitions. The industry structure we look at involves a few dominant banks and a competitive fringe, which we take as the structure most likely to resemble the Turkish banking industry in the aftermath of the ongoing restructuring process. Using a reasonable set of parameters to simulate the model, we perform comparative statics exercises regarding the impact of mergers among domestic as well as with foreign banks on equilibrium outcomes.
