Corporate social responsibility,profits and welfare with managerial firms

This paper analyses the equilibrium outcomes in a duopoly market where firms follow corporate social responsibility (CSR) behaviours under managerial delegation. It is shown that in the subgame perfect Nash equilibrium of the game, both firms emerge as CSR-type, and the firms’ profitability (resp. the welfare of consumers and society) are beneficiated (resp. harmed) by the CSR behaviour. This result is in sharp contrast with the conventional result (established under non-managerial firms) that the higher the CSR sensitivity to consumer surplus, the lower (resp. higher) the firms’ profitability (resp. the consumer surplus and social welfare).     

EQUILIBRIA EXISTENCE AND CHARACTERIZATION IN AUCTIONS: ACHIEVEMENTS AND OPEN QUESTIONS

Abstract Establishing existence and characterizing equilibria are both important achievements in the study of auctions. However, we recognize that equilibria existence results form the basis for well accepted characterizations. In this survey, we review the landmark results and highlight open questions regarding equilibria existence and characterizations in auctions. In addition, we review the standard assumptions underlying these results, and discuss the suitability of the Nash equilibrium solution concept. We focus our review on single‐object auctions, but also review results in multi‐unit, divisible, combinatorial and double auctions.     

Insider trading in an equilibrium model with default: a passage from reduced-form to structural modelling

We study, in the framework of Back [Rev. Financial Stud. 5(3), 387–409 (1992)], an equilibrium model for the pricing of a defaultable zero coupon bond issued by a firm. The market consists of a risk-neutral informed agent, noise traders, and a market maker who sets the price using the total order. When the insider does not trade, the default time possesses a default intensity in the market’s view as in reduced-form credit risk models. However, we show that, in equilibrium, the modelling becomes structural in the sense that the default time becomes the first time that some continuous observation process falls below a certain barrier. Interestingly, the firm value is still not observable. We also establish the no expected trade theorem that the insider’s trades are inconspicuous.      

Macroeconomic policy regimes,real exchange rate overvaluation,and performance of the Brazilian economy (2003–2015)

The objective of this article is to present a review of the workings of the macroeconomic policy regimes in Brazil since 2003 in order to show that both the macroeconomic policy tripod and the new macroeconomic matrix were not capable of ensuring macroeconomic stability in the medium- to long term due to their incapacity to avoid a persistent overvaluation of the real exchange rate or to stop the increasing trend in primary expenditures/gross domestic product, which produced a major fiscal crisis in 2015.     

The inception of internationalization of small and medium enterprises: The role of activeness and networks

This study analyzes how exporters begin their internationalization leveraging information collected through interviews with 109 Chinese textile manufacturers. It examines whether firms that found their first international clients through a “proactive” search are likely to export faster, more intensively, and to a larger number of markets. The findings illustrate that the proactiveness of the search for the first client in a foreign market is an important predictor of the intensity and geographic scope of the firm's internationalization path but not of its speed. They support the view of internationalization as an actively pursued entrepreneurial process, which may also be affected by serendipitous events. This study provides new evidence on the first international business discovery of Chinese exporters, contributing to the literature on international entrepreneurship, international new ventures and the network approach to internationalization.     

Differentiation strategies in emerging markets: The case of Latin American agribusinesses

This study furthers the research agenda on Porter's generic strategies by exploring their implementation by firms that suffer from under representation in the literature. It focuses on agribusinesses based in emerging markets that specialize in high value added products. Relying on information collected through interviews, and a survey with 66 agribusinesses based in eight countries of Latin America, it examines the factors that distinguish firms implementing a differentiation strategy (DS). The findings provide interesting insights for scholars and practitioners alike, illustrating the strategic initiatives that DS firms use to ensure they command higher than average prices.

Stability Analysis in a Bertrand Duopoly with Different Product Quality and Heterogeneous Expectations

We study the local stability properties of a nonlinear Bertrand duopoly with vertical differentiation and heterogeneous players under the hypotheses of both covered and uncovered markets. In the former case, the unique pure strategy Nash equilibrium can undergo a flip bifurcation when the extent of consumer’s heterogeneity increases. In the latter, the quality differential determines the stability of prices over time. Numerical evidence is provided to show the occurrence of endogenous fluctuations.     

A multivariate jump-driven financial asset model

We discuss a Lévy multivariate model for financial assets which incorporates jumps, skewness, kurtosis and stochastic volatility. We use it to describe the behaviour of a series of stocks or indexes and to study a multi-firm, value-based default model. Starting from an independent Brownian world, we introduce jumps and other deviations from normality, including non-Gaussian dependence. We use a stochastic time-change technique and provide the details for a Gamma change. The main feature of the model is the fact that—opposite to other, non-jointly Gaussian settings—its risk-neutral dependence can be calibrated from univariate derivative prices, providing a surprisingly good fit.
