Factor price equalization? The cointegration approach revisited

Conclusions Absolute factor price equalization across countries is a key prediction of the Heckscher-Ohlin-Samuleson model of international trade, one of the more influential “workhorse” models in economics. Despite its theoretical might, the factor price equalization hypothesis has received surprisingly little empirical support. In an important exception to the rule, Burgman and Geppert (1993) argue that this might be due to the neglect of the non-stationarity of the time series under consideration. And indeed, applying a cointegration approach to (nominal) unit labor costs in six major industrialized countries (Canada, France, Germany, Japan, the United Kingdom, and the United States), they find evidence of long-run factor price co-movement. This finding can be interpreted as being in line with equalization of factor prices amongst these countries.     

How Do Large Banking Organizations Manage Their Capital Ratios?

U.S. banks hold significantly more equity capital than required by their regulators. We test competing hypotheses regarding the reasons for this “excess” capital, using an innovative partial adjustment approach that allows estimated BHC-specific capital targets and adjustment speeds to vary with firm-specific characteristics. We apply the model to annual panel data for publicly traded U.S. bank holding companies (BHCs) from 1992 through 2006, an extended period of increasing bank capital that ended just before the subprime credit crisis of 2007–2008. The evidence suggests that BHCs actively managed their capital ratios (as opposed to passively allowing capital to build up via retained earnings), set target capital levels substantially above well-capitalized regulatory minima, and (especially poorly capitalized BHCs) made rapid adjustments toward their targets.     

TIME VARIABILITY IN MARKET RISK AVERSION

We adopt realized covariances to estimate the coefficient of risk aversion across portfolios and through time. Our approach yields second moments that are free from measurement error and not influenced by a specified model for expected returns. Supporting the permanent income hypothesis, we find risk aversion responds to consumption-smoothing behavior. As income increases, or as the consumption-to-income ratio falls, relative risk aversion decreases. We also document variation in risk aversion across portfolios: risk aversion is highest for small and value portfolios.     

Fictitious play in 2×n games

It is known that every discrete-time fictitious play process approaches equilibrium in nondegenerate 2×2 games, and that every continuous-time fictitious play process approaches equilibrium in nondegenerate 2×2 and 2×3 games. It has also been conjectured that convergence to the set of equilibria holds generally for nondegenerate 2×n games. We give a simple geometric proof of this for the continuous-time process, and also extend the result to discrete-time fictitious play.

Why Do Recent Graduates Enter into Flexible Jobs?

Flexible jobs make up a larger share of the Dutch labour market than in almost any other Western country. Recent graduates in the Netherlands are particularly likely to take flexible jobs. In this study we examine why recent graduates enter into temporary contracts and whether flexible jobs offer a poorer match for graduates’ qualifications than permanent jobs. We find that recent graduates that enter into flexible jobs face large wage penalties, a worse job match and less training participation than graduates who take permanent jobs, even after correcting for differences in ability. When the labour market situation for a particular field of education deteriorates, more recent graduates are forced into flexible jobs, threatening their position on the labour market in the long run. Flexible work among recent graduates is unrelated to their willingness to take risks. Only for university graduates is there any indication that flexible jobs may provide a stepping stone to permanent employment.     

Variance Estimation of Imputed Estimators of Change for Repeated Rotating Surveys

A common problem in survey sampling is to compare two cross‐sectional estimates for the same study variable taken from two different waves or occasions. These cross‐sectional estimates often include imputed values to compensate for item non‐response. The estimation of the sampling variance of the estimator of change is useful to judge whether the observed change is statistically significant. Estimating the variance of a change is not straightforward because of the rotation in repeated surveys and imputation. We propose using a multivariate linear regression approach and show how it can be used to accommodate the effect of rotation and imputation. The regression approach gives a design‐consistent estimation of the variance of change when the sampling fraction is small. We illustrate the proposed approach using random hot‐deck imputation, although the proposed estimator can be implemented with other imputation techniques.     

Testing for time variation in the natural rate of interest

This paper replicates in a wider sense the unobserved components model of Laubach and Williams (Review of Economics and Statistics, 2003, 85, 1063–1070) to estimate the natural rate of interest (NRI) and investigates the role of model uncertainty. A stochastic Bayesian model selection procedure is employed to test the hypothesis of time variation in the NRI against a constant NRI. The model selection confirms time variation in the NRI as a result of changes in potential output growth, but other determinants of the NRI are found constant.     

Kick‐starting diffusion: Explaining the varying frequency of preferential trade agreements’ environmental provisions by their initial conditions

Most recent preferential trade agreements (PTAs) include environmental provisions. While a number of these environmental provisions remain rare and are incorporated in just a few PTAs, others are widely popular and are duplicated in more than 100 PTAs. We still lack a convincing explanation for this varying frequency. While the diffusion literature typically tries to explain how diffusion occurs, we investigate why certain provisions diffuse more often than others. We hypothesise that the initial conditions under which provisions first emerge determine the scope of their diffusion. Our results support this hypothesis and indicate that provisions originating from intercontinental agreements diffuse more often than others. At the same time, provisions first designed by economically powerful or environmentally credible countries are not related to more frequent occurrences of diffusion. These findings are of interest for the literatures on international institutions' design, interaction and diffusion.     

Solutions to the request reassignment problem in collaborative carrier networks

The paper considers an arrangement for exchanging transportation requests to facilitate collaboration among independent carriers. The goal is to maximize the total profit without decreasing the individual profit of the carriers. Two solution approaches are developed for this problem involving decentralized control and auction based exchange mechanisms. The results are compared with those obtained without collaboration and by a centralized control. They indicate that horizontal collaboration pays off even in highly competitive environments.
