Concept‐Based Bayesian Model Averaging and Growth Empirics

In specifying a regression equation, we need to specify which regressors to include, but also how these regressors are measured. This gives rise to two levels of uncertainty: concepts (level 1) and measurements within each concept (level 2). In this paper we propose a hierarchical weighted least squares (HWALS) method to address these uncertainties. We examine the effects of different growth determinants taking explicit account of the measurement problem in the growth regressions. We find that estimates produced by HWALS provide intuitive and robust explanations. We also consider approximation techniques which are useful when the number of variables is large or when computing time is limited.     

Capital controls and the location of industry

This paper studies capital controls on the outflow of capital in a two-region new economic geography model. Capital controls are set in a non-cooperative or cooperative manner by social planners. Capital controls are relatively higher in the North in the non-cooperative equilibrium. This leads to relatively more firms located in the region where more consumers reside under the non-cooperative equilibrium. The locational bias towards the North in the non-cooperative equilibrium becomes larger as trade barriers are reduced. That is, firms locate to the North at a relatively higher rate in the non-cooperative equilibrium as trade is liberalised. Contrary to previous findings, it follows that global welfare is relatively higher in the non-cooperative equilibrium, although the social planner sets capital controls by maximising joint regional welfare in the cooperative equilibrium.     

Third-party certification and post-IPO acquisitions

ABSTRACT

We explore the link between third-party certification (venture capital backing, analyst following and having a top underwriter), and post-IPO acquisition activity through the reduction in valuation uncertainty channel. In a sample of 2,424 U.S. IPOs, we find that third-party certification facilitates post-IPO acquisitions. The certified firms are both more likely and conduct acquisitions sooner after the IPO. Our results support the notion that third-party certification reduces post-IPO valuation uncertainty and thereby facilitates a more efficient acquisition strategy.     

Humility in Business: A Contextual Approach

The virtue of humility is often considered to be at odds with common business practice. In recent years, however, scholars within business ethics and leadership have shown an increasing interest in humility. Despite such attention, the argument for the relevance of humility in business could be expanded. Unlike extant research that focuses on humility as a character-building virtue or instrumentally useful leadership trait, this article argues that humility reflects the interdependent nature of business. Through such an approach, the article gives an extrinsic motivation of the relevance of humility in business, and, from a theoretical point of view, links the intra-personal and intra-organizational perspective on humility to an inter-organizational one. The article contextualizes the virtue of humility by relating it to the economic, cognitive, and moral aspects of business practice and managerial work. It claims that the assumption of self-sufficiency in business is a grave misrepresentation of what business is—a practice characterized by interdependency. Potential links between virtue ethics, leadership, and contextually oriented theories of business, such as stakeholder theory, network theories, and resource dependence theory, are also identified.     

Migrants’ Influence on Firm-level Exports

We examine the role of migrants in trade using a firm-level approach. We exploit a new employer–employee panel for Sweden, which encompasses close to 600,000 full-time employees, approximately 12,000 firms and data for 176 countries for the period 1998–2007. The resulting analysis provides novel firm-level evidence on the trade-migration relationship. Foreign-born workers have a positive association with firm exports. However, immigrants do not have an unconditional positive impact on firm trade. Mainly small firms gain from hiring foreign-born workers, and migrants need to be skilled and recently arrived to have a clear positive impact on firm export performance.     

The presence of unemployment hysteresis in the OECD: what can we learn from out-of-sample forecasts?

This paper investigates the relevance of unemployment hysteresis in seventeen OECD countries. We employ an out-of-sample forecast exercise in which a mean-reverting autoregressive model is compared to an autoregressive model with an imposed unit root. A substantial difference in forecasting performance between the two models is established for many countries, but the results are mixed in their strength. The evidence for unemployment hysteresis in Austria, Finland, Iceland, Israel, Italy, Japan and Sweden is, however, convincing. For no country can unambiguous support for a mean reverting unemployment rate be found.     

The efficiency of top agents: An analysis through service strategy in tennis

We consider the question whether top tennis players in a top tournament (Wimbledon) employ an optimal (efficient) service strategy. While we show that top players do not, in general, follow an optimal strategy, our principal result is that the estimated inefficiencies are not large: the inefficiency regarding winning a point on service is on average 1.1% for men and 2.0% for women, implying that–by adopting an efficient service strategy–players can (on average) increase the probability of winning a match by 2.4%-points for men and 3.2%-points for women. While the inefficiencies may seem small, the financial consequences for the efficient player at Wimbledon can be substantial: the expected paycheck could rise by 18.7% for men and even by 32.8% for women. We use these findings to shed some light on the question of whether economic agents are successful optimizers.     

Reply to: pricing of card payment services in Scandinavian banking: a comment,by Leo Van Hove

A comment on the previously published paper ‘Pricing of card payment services in Scandinavian banking’ has been written by Leo Van Hove and published in this issue of The Service Industries Journal; it suggests alternative analytical approaches and other implications of the results. This reply develops the study further, providing new presentations of the empirical data and discussing its conclusions. The suggestions and approaches provided by Van Hove do not change the conclusions drawn in the paper, and in-depth implications of the results in a wider context are outside the scope of the paper. However, this reply proposes further empirical studies regarding the pricing of card payment services.     

Pricing of card payment services in Scandinavian banking

Pricing of card payment services includes many considerations of cost and revenue in an environment of changing payment technology, network effects in two-sided markets and price bundling. This paper describes the consumer pricing methods for card payment services by Scandinavian banks and evaluates their explicit pricing methods. The main findings suggest that Scandinavian banks in general are more interested in earning revenue from implicit prices than in encouraging the use of more cost efficient technology by charging explicit transaction fees. However, the pricing methods applied may vary, depending on the country and a bank's service supply.     

Regularized conditional estimators of unit inefficiency in stochastic frontier analysis,with application to electricity distribution market

In stochastic frontier analysis, the conventional estimation of unit inefficiency is based on the mean/mode of the inefficiency, conditioned on the composite error. It is known that the conditional mean of inefficiency shrinks towards the mean rather than towards the unit inefficiency. In this paper, we analytically prove that the conditional mode cannot accurately estimate unit inefficiency, either. We propose regularized estimators of unit inefficiency that restrict the unit inefficiency estimators to satisfy some a priori assumptions, and derive the closed form regularized conditional mode estimators for the three most commonly used inefficiency densities. Extensive simulations show that, under common empirical situations, e.g., regarding sample size and signal-to-noise ratio, the regularized estimators outperform the conventional (unregularized) estimators when the inefficiency is greater than its mean/mode. Based on real data from the electricity distribution sector in Sweden, we demonstrate that the conventional conditional estimators and our regularized conditional estimators provide substantially different results for highly inefficient companies.
