Regionalisation versus regionalism— Problems of change in the world economy

The distinct trends towards regionalisation in the world economy that could be observed in recent years should not be interpreted merely as the formation of economic blocs or “fortresses”. This would amount to adopting a biased, backward-looking approach that sees only the sombre experiences of the thirties and forties and does not take sufficient account of the different challenges of the post-war period.     

Humorous coping scales and their fit to a stress and coping framework

The focus of this study is on the fit between the item content of scales measuring humorous coping and basic concepts of stress and coping theory. To investigate this fit 81 items from seven currently available humorous coping scales have been subjected to a facet analysis, using the tool of a mapping sentence. Three facets derived from stress and coping theory were part of this mapping sentence: external demands, humorous responses and coping aims. Because of the claim that humorous coping may be related to physical health dimensions, special attention has been paid to two health-related coping aims: cognitive reappraisal and response-focused coping responses. Five raters categorized the facets and their respective categories. Some humorous coping scales showed an underrepresentation of “external demands” and “humorous responses” and only a few scales covered the “aims” facet adequately. Reliability and agreement parameters varied considerably among scales, both on facet level and on category level. The Waterloo University Humor Inventory (WUHI) was a positive exception to this pattern. Findings are discussed in the light of specific characteristics of the scales included. Possible improvements of humorous coping measurement in health-related research are proposed, as well as adaptations to the rating procedures.     

International tourism demand and the business cycle

The focus of this study is on presenting causes and hypotheses for the existence of asymmetric income and price effects on tourism demand across business cycles. The theoretical assumptions were tested by analyzing tourism import demand in different source markets, drawing on econometric models that provide for the magnitudes of price and income effects either to vary depending on the phase of the business cycle or to remain stable across the business cycles. The major outcome of this study is that the general assumption in most of the tourism demand studies—i.e. that the income effects are symmetric—should not be expected to be automatically true for every source market.     

Misallocation and financial market frictions: Some direct evidence from the dispersion in borrowing costs

Financial frictions distort the allocation of resources among productive units—all else equal, firms whose financing choices are affected by such frictions face higher borrowing costs than firms with ready access to capital markets. As a result, input choices may differ systematically across firms in ways that are unrelated to their productive efficiency. We propose an accounting framework that allows us to assess empirically the magnitude of the loss in aggregate resources due to such misallocation. To a second-order approximation, the framework requires only information on the dispersion in borrowing costs across firms, which we measure—for a subset of U.S. manufacturing firms—directly from the interest rate spreads on their outstanding publicly-traded debt. Given the observed dispersion in borrowing costs, our approximation method implies a relatively modest loss in efficiency due to resource misallocation—on the order of 1 to 2 percent of measured total factor productivity (TFP). In our framework, the correlation between firm size and borrowing costs has no bearing on TFP losses under the assumption that financial distortions and firm-level efficiency are jointly log-normally distributed. To take into account the effect of covariation between firm size and borrowing costs, we consider a more general framework, which dispenses with the assumption of log-normality and which implies somewhat higher estimates of the resource losses—about 3.5 percent of measured TFP. Counterfactual experiments indicate that dispersion in borrowing costs must be an order of magnitude higher than that observed in the U.S. financial data, in order for misallocation—arising from financial distortions—to account for a significant fraction of measured TFP differentials across countries.
