IPO and Aftermarket Performance of Single‐Listed Chinese ADRs

This paper analyzes the post‐IPO and long‐run aftermarket performances of single‐listed Chinese ADRs during the 2004–2010 period. Single‐listed ADRs are traded daily in major exchanges in the United States, but their underlying shares are not traded in the issuer's home market. Our results show that over the short‐run, buy‐and‐hold abnormal returns of single‐listed Chinese ADRs following their IPO are not significantly different from the typical post‐IPO performance of stocks in U.S. exchanges, including that of traditional dual‐listed Chinese ADRs. Nevertheless, over the longer horizon, the excess returns of a portfolio composed solely of single‐listed Chinese ADRs outperform a portfolio of dual‐listed Chinese ADRs, but underperform a benchmark portfolio composed of U.S. firms matched on the basis of their IPO date. We also find that the portfolio formed solely of single‐listed Chinese ADRs exhibits significantly distinct loadings on the common portfolio factors from the portfolio formed of dual‐listed Chinese ADRs and from the benchmark portfolio of U.S. stocks.     

Estimating technology in the postal sector: a Bayesian approach

The aim of this article is to study the technology of the sector represented by the Spanish national post-office and telegraph service, Sociedad Estatal Correos y Telégrafos, S.A. trading as Correos, and denominated as such hereafter. Concretely, we analyse economic efficiency (technical and allocative) and scale economies of the production units (cost centres) of Correos. To do this, we employ a methodology based on an input distance function which is the dual of the cost function. Moreover, and applying duality theory, we develop an economic model to assess the effect of postal infrastructures on the operators’ costs. In order to carry out the empirical model, Bayesian econometrics is applied to estimate the parameters in the input distance function and the technical and allocative efficiency terms.     

Exchange Rates,Employment and Labour Market Rigidity

In this paper, we study the effect of labour market rigidity on the impact of exchange rate shocks on employment. We use a panel dataset comprising 22 manufacturing sectors across 23 OECD countries. In our econometric model, the impact of exchange rate fluctuations on sectoral employment is mediated by the degree of openness and by a measure of labour market rigidity: the OECD's employment protection legislation (EPL) index. Our results suggest that greater labour market rigidity reduces the impact of exchange rate shocks on employment. This effect is statistically significant for low‐technology sectors.     

Time and uncertainty in resource dilemmas: equilibrium solutions and experimental results

Most common pool resource (CPR) dilemmas share two features: they evolve over time and they are managed under environmental uncertainties. We propose a stylized dynamic model that integrates these two dimensions. A distinguishing feature of our model is that the duration of the game is determined endogenously by the users’ collective decisions. In the proposed model, if the resource stock level below which the irreversible event occurs is known in advance, then the optimal resource use coincides with a unique symmetric equilibrium that guarantees survival of the resource. As the uncertainty about the threshold level increases, resource use increases if users adopt decision strategies that quickly deplete the resource stock, but decreases if they adopt path strategies guaranteeing that the unknown threshold level is never exceeded. We show that under relatively high uncertainty about resource size, CPR users frequently implement decision strategies that terminate the game immediately. When this uncertainty is reduced, they maintain a positive resource level for longer durations.     

Heritage tourism clusters along the borders of Mexico

This article seeks to find potential heritage tourism clusters in border areas. Literature about tourism destinations is essentially focused on administrative-bound areas, while little attention has been paid to functional regions. The research is based on a methodological exercise to contribute to this debate by analyzing the case of three border regions between Mexico, the USA, Guatemala and Belize, respectively. These borders have never been static but have changed throughout history, to the present day situation. It is argued that these changes have implications for the potential development of heritage tourism. The results identify a number of cross-border clusters and corridors in these areas with different levels of tourism underdevelopment, mainly because of political or legal restrictions. The results of this study contribute to an improved understanding of borderland heritages and cross-border regional clusters in the context of tourism.     

Franchise,innovation and entrepreneurship

Since franchise business can be an alternative to independent business, it seems interesting to look at those factors that encourage individuals to choose franchise rather than independent business. It is also relevant to consider the role of innovation because it is generally accepted that independent business facilitates innovations to a greater degree than does franchise. The main goal of this paper is to determine the factors that encourage individuals to choose franchise activity and what role plays innovation in their decision.     

Import Churning and Export Performance of Multi‐product Firms

This paper analyses the impact of churning in the imported varieties of capital and intermediate inputs on firm export scope and productivity. Using detailed data on imports and exports at the firm‐product‐market level, we document substantial churning in both imports and exports for Slovenian manufacturing firms in the period 1994–2008. On average, a firm changes about one‐quarter of imported and exported product‐markets every year, while gross churning in terms of added and dropped product‐markets is almost three times higher. A substantial share of this product churning is due to simultaneous imports and exports of firms in identical varieties within the same CN‐8 product code (so called pass‐on‐trade). We find that churning in imported varieties is far more important than reduction in tariffs or declines in import prices for firms’ productivity growth and increased export product scope. We also find gross churning has a bigger impact on firm productivity improvements by a factor of more than 10 in comparison with net churning. Both adding and dropping of imported input varieties thus seem to be of utmost importance for firms aiming to optimise their input mix towards their most valuable inputs. These effects are further enhanced when excluding simultaneous trade in identical varieties, suggesting that pass‐on‐trade has less favourable effects on firms’ long‐run performance than regular trade.     

SEBI index: Measuring the commitment to the principles of social banking

As a result of the financial crisis, ethical banking has become a visible phenomenon that has aroused the interest of those clients that are disappointed with conventional banking, as well as that of the scientific community. However, research on ethical banking has just started, with several subjects pending consensus, such as the proper definition or identification of banks considered to be ethical. In view of the above, the objective of this study is, first and foremost, to define the common characteristics of all banks affiliated to the movement; empirically, we shall quantify the level of commitment with the same and, thus, as a result of this quantification, obtain a ranking that classifies the selected banks according to the scores obtained. Regarding the methodology used, the quantification of the level of commitment with ethical banking is done through a new index called SEBI (Social and Ethical Banking Index), designed from the characteristics defined in the study and applied to the banks identified as ethical due to being a part of the main network of this type of banking: The Global Alliance for Banking on Values (GABV).
