Inequality and trade

Abstract.  We incorporate demand‐side considerations in trade in a systematic but straightforward way. We do so by focusing on the role of inequality in the determination of trade flows and patterns. With non‐homothetic preferences, when countries are similar in all respects but asset inequality, we find that trade is driven by specialization in consumption , not production. Besides, these assumptions allow us to generate some interesting international spillover effects of redistributive policies. Finally, we study a model of monopolistic competition and find a novel V‐shaped relationship between the ratio of inter‐industry to intra‐industry trade and a country's inequality.

Parametric and nonparametric statistical modelling of crop yield: implications for pricing crop insurance contracts

This article considers alternative methods to calculate the fair premium rate of crop insurance contracts based on county yields. The premium rate was calculated using parametric and nonparametric approaches to estimate the conditional agricultural yield density. These methods were applied to a data set of county yield provided by the Statistical and Geography Brazilian Institute (IBGE), for the period of 1990 through 2002, for soybean, corn and wheat, in the State of Paraná. In this article, we propose methodological alternatives to pricing crop insurance contracts resulting in more accurate premium rates in a situation of limited data.     

Behavioral Finance in Brazil: A Bibliometric Study from 2007 to 2017

This article analyzed 58 Brazilian journals in order to address the gap unexplored in the past 10?years by congresses and periodical journals. In this research, an analysis based on keywords was used, followed by analysis of citations and co-citations that allowed to verify: an average growth of 20% p.a. of publications; the most common focus was replication of Kahneman and Tversky; the most studied group tended to be university students; quality has failed to accompany the increase in publications; public institutions publish more. A gap was perceived in the surveying of financial managers and investors, as well as bias and heuristics as a subject.     

Apple's disaster: Linking two‐sided markets and strategic delegation

Asymmetric pricing structure and different intergroup network externalities are characteristics of two‐sided markets not captured in the analysis of one‐sided markets. Focusing on Cournot duopoly where membership decision may be delegated to a manager, several equilibrium regimes are sustained depending on the fixed cost of managerial hiring and strength of the network externality exerted by the side whose demand is more price sensitive. The change from null to full delegation sharpens the asymmetric pricing structure and reduces the price level in two‐sided markets. Contrary to one‐sided markets with direct network effects, the prisoner's dilemma holds for sufficiently strong indirect network externalities. Imperfect interside discrimination of managerial incentives ensures profit maximization and efficient consumers' allocation. Private hiring should occur when the two‐sided market exhibits symmetric pricing structure. An explanation for Apple's unprecedented event is provided. The reduction of revenue and managerial bonus in 2016 may be justified by the dissemination of full delegation in the Chinese information technology industry. Apple's upcoming strategy may consist on reducing both access prices, although the side whose demand is more price sensitive should have a greater price reduction. Alternatively, improving the content quality may constitute Apple's corporate strategy, thereby inducing a skimming pricing strategy on Chinese rivals.     

NESTING VERTICAL AND HORIZONTAL DIFFERENTIATION IN TWO‐SIDED MARKETS

We merge the two‐sided markets duopoly model of Armstrong (2006) with the nested vertical and horizontal differentiation model of Gabszewicz and Wauthy (2012), which consists of a linear city with different consumer densities on the left and on the right side of the city. In equilibrium, the high‐quality platform sells at a higher price and captures a greater market share than the low‐quality platform, despite the indifferent consumer being closer to the high‐quality platform. The difference between market shares is lower than socially optimal. A perturbation that introduces a negligible difference between the consumer density on the left and on the right side of the city may disrupt existence of equilibrium in the model of Armstrong (2006).

Fiscal consolidation and financial reforms

We use a rare events logistic regression model as well as traditional probit and logit models to investigate the impact of fiscal consolidation on the likelihood of financial reforms for a panel of 17 countries over the period 1980–2005. We show that large austerity plans, mainly implemented through spending cuts rather than tax hikes, promote financial reforms. By considering reforms affecting specific areas of the financial sector, we find that the banking sector reforms and domestic finance reforms are more likely to occur when fiscal adjustments are put in place. Interestingly, while banking sector reforms are mainly prompted during periods of tax-driven consolidations, spending cuts driven consolidation packages seem to propel the implementation of domestic finance reforms. Finally, we show that higher inflation, lower degree of trade openness, a deterioration of financial conditions and, to some extent, a fall in the degree of competitiveness enhance the probability of financial reforms.     

Global mindset and the internationalization of small firms: The importance of the characteristics of entrepreneurs

Despite being a relatively new concept, the importance of the global mindset is already well-documented. So far research has primarily focused on multinational companies and therefore the operationalization of the concept is still a work in progress. Recognizing the importance of entrepreneurs in small companies, yet mindful of the gaps that exist, this paper addresses the factors that constitute the global mindset and their influence on the internationalization of small Portuguese companies. Using information-processing theory through a quantitative, survey-based study and Structural Equation Modeling (SEM), the results show the importance of the characteristics of both entrepreneurs and firms in explaining the global mindset, and confirm the impact they have on internationalization behavior. The entrepreneur??s level of education, their satisfaction with company performance in the domestic market and the potential for growth in the domestic market all affect the global mindset model. The conclusions are useful for entrepreneurs and national authorities aiming to successfully implement internationalization practices, given the role of the global mindset in exploring global business opportunities and in the global success of companies. Replication of the research in different contexts is essential for the wider generalization of the results.     

Employing the business model concept to support the adoption of product–service systems (PSS)

Although the existing literature indicates that the business model concept can be useful to implement product–service systems (PSS), there is still a paucity of guidelines to assist companies in this respect. Therefore, this paper proposes a framework to support the adoption of PSS employing the business model concept. This framework was developed based on literature review and intends to guide the company on the analysis of their business context, on the choice of the appropriate type of PSS and on the definition of their PSS characteristics. A single case study was then performed to illustrate an application of the framework in a machine tool manufacturer and provide research insights. Overall, results indicate that the framework can provide companies with a useful reference to PSS implementation, helping on the investigation of different PSS scenarios as well as the main barriers and challenges to be overcome.     

The impact of the European Union fiscal rules on economic growth

This paper analyses whether Maastricht and Stability and Growth Pact fiscal rules have affected growth in the European Union negatively. A growth equation is specified for a group of 15 European Union countries (and 8 OECD countries) over the period 1970-2005 to analyse this issue. Panel estimations using fixed-effects, pooled mean group and system-GMM estimators show that the institutional changes that occurred in the European Union after 1992 were not harmful to growth. Moreover, results show that growth is slightly higher in the period in which the fulfilment of the 3% criteria for the deficit started to be officially assessed, i.e. after 1997.
