Sustainable banking in Latin American developing countries: Leading to (mutual) prosperity

This article examines multinational banks’ (MNBs) approaches to corporate social responsibility (CSR) in developing countries’ subsidiaries, particularly in Latin America. Building on in-depth case studies of two MNBs that are based in Europe and market leaders in Latin America, we analyze their CSR motivations and outcomes in host countries. We examine institutional environments by applying the national business system framework, and we suggest missing categories in its financial and educational dimensions. We theorize how institutional necessity determines MNBs' CSR in developing countries. Finally, we examine the CSR outcomes in Latin America, where banks’ responsible conduct has led to major improvements in educational levels and financial inclusion. These improvements alleviate poverty and enhance both country's social wellbeing and MNBs’ legitimacy, leading to mutual prosperity.     

Government size,composition of public expenditure,and economic development

This paper analyzes the effects of government size and of the composition of public expenditure on economic development. Using the system-GMM estimator for linear dynamic panel data models, on a sample covering up to 156 countries and 5-year periods from 1980 to 2010, we find that government size as a percentage of GDP has a quadratic (inverted U-shaped) effect on the growth rate of the Human Development Index (HDI). This effect is especially pronounced in developed and high-income countries. We also find that the composition of public expenditure affects development, with the share of five subcomponents exhibiting nonlinear relationships with HDI growth.     

Asymmetric rivalry within and between strategic groups

Our study examines asymmetric rivalry within and between strategic groups defined according to the size of their members. We hypothesize that, owing to several forms of group‐level effects, including switching costs and efficiency, strategic groups comprising large firms expect to experience a large amount of retaliation from firms within their group and accommodation from the group comprising smaller firms. Small firms, on the other hand, expect to experience a small amount of retaliation from the group comprising large firms and no reaction from the other firms in their group. We estimate the effect of group‐level strategic interactions on firm performance. Our analysis reveals that the rivalry behavior within and between groups is asymmetric, which supports the dominant‐fringe relation between firms, as described in our hypothesis.

Holt’s exponential smoothing and neural network models for forecasting interval-valued time series

Interval-valued time series are interval-valued data that are collected in a chronological sequence over time. This paper introduces three approaches to forecasting interval-valued time series. The first two approaches are based on multilayer perceptron (MLP) neural networks and Holt’s exponential smoothing methods, respectively. In Holt’s method for interval-valued time series, the smoothing parameters are estimated by using techniques for non-linear optimization problems with bound constraints. The third approach is based on a hybrid methodology that combines the MLP and Holt models. The practicality of the methods is demonstrated through simulation studies and applications using real interval-valued stock market time series.     

Economic growth, labor market and demographic patterns

This study addresses the dynamic interaction between income growth, patterns of demographic variables, and characteristics of the labor market. We attempt to provide an endogenous explanation for the origin and nature of long-run sustained oscillations in the population and in economic variables. First, we develop an economic growth model containing unemployment. The resulting dynamics reveal that the emergence of irregular sustained oscillations is related to the lack of sensitivity in wage growth to changes in the employment rate. Next, labor force growth is endogenized in the basic model through micro-founded fertility choices of individuals. By introducing the endogenous fertility rate into the basic model, we generate a demographic transition. Next, consistent with Malthusian cycle literature, the inevitable time lag between individual reproductive decisions and subsequent market needs, in conjunction with a highly specialized labor force, appear to be the primary source of such long-run oscillations. Finally, the model predicts that raising the age of entry into the labor force increases economic growth.     

The effect of ambiguous risk, and coordination on farmers' adaptation to climate change — A framed field experiment

The risk of losses of income and productive means due to adverse weather can differ significantly among farmers sharing a productive landscape, and is of course hard to estimate, or even “guesstimate” empirically. Moreover, the costs associated with investments in reduced vulnerability to climatic events are likely to exhibit economies of scope. We explore the implications of these characteristics on farmer's decisions to adapt to climate change using a framed field experiment applied to coffee farmers in Costa Rica. As expected, we find high levels of risk aversion, but even using that as a baseline, we further find that farmers behave even more cautiously when the setting is characterized by unknown or ambiguous risk (i.e. poor or non-reliable risk information). Secondly, we find that farmers, to a large extent, coordinated their decisions to secure a lower adaptation cost, and that communication among farmers strongly facilitated coordination.     

Serial entrepreneurship: impact of human capital on time to re-entry

This study uses a longitudinal matched employer–employee database to examine how ex-entrepreneurs’ levels of general and specific human capital influence their likelihood of re-entering entrepreneurship over time, in a different firm, thereby becoming serial entrepreneurs. The results reveal a negative effect of general human capital on the hazard of becoming a serial entrepreneur; the impact of entrepreneurial-specific human capital on the hazard of re-entering entrepreneurship is in general positive. This research provides a dynamic approach to serial entrepreneurship revealing that specific types of human capital play distinct roles on individuals’ entrepreneurial behavior.     

Rivalry within strategic groups and consequences for performance: the firm‐size effects

Our study examines how, in a given industry, rivalry functions within strategic groups defined according to the size of their member firms and how this rivalry affects performance. We hypothesize that, owing to several forms of group‐level effects including market power, efficiency, differentiation, and multimarket contact, strategic groups that comprise smaller firms will exhibit both increased rivalry and decreased performance compared with strategic groups that comprise larger firms. We test our hypotheses by estimating the effect of group‐level strategic interactions (i.e., conjectural variations) on firm performance. Ultimately, our analysis of empirical data on loans in the Spanish banking industry demonstrates that increased rivalry and decreased performance indeed characterizes firms belonging to a strategic group that comprises smaller firms.
