The importance of the Logistics Performance Index in international trade

Logistics and transport increasingly play a pivotal role in international trade relations. The Logistics Performance Index (LPI) analyses differences between countries in terms of customs procedures, logistics costs and the quality of the infrastructure for overland and maritime transport. The aim of this article is to analyse the impact that each of these components has on trade in emerging economies using a gravity model. Furthermore, the study also attempts to detect possible advances in logistics in developing countries, which are grouped into five regions (Africa, South America, Far East, Middle East and Eastern Europe) by comparing the first LPI data published in 2007 with the most recent data, released in 2012. The results obtained reveal that improvements in any of the components of the LPI can lead to significant growth in a country’s trade flows. Specifically, LPI components are becoming increasingly important for international trade in many countries in Africa, South America and Eastern Europe.     

WHY ARE FERTILITY RATES AND FEMALE EMPLOYMENT RATIOS POSITIVELY CORRELATED ACROSS O.E.C.D. COUNTRIES?*

We develop a quantitative theory of fertility and labor market participation decisions in order to investigate the role of labor market frictions in generating the observed positive association between fertility and employment among O.E.C.D. countries. We find that unemployment induces females to postpone and space births, which, in turn, reduces the total fertility rate. Moreover, differences in female labor outcomes across the United States and Spain can account for the low fertility rate in Spain relative to the United States. We also find that labor market frictions can generate a positive association between female employment ratios and fertility rates across economies.     

Relationship between individualist–collectivist culture and entrepreneurial activity: evidence from Global Entrepreneurship Monitor data

This paper examines how one dimension of national culture (an individualist–collectivist orientation) is related to Total Entrepreneurial Activity, depending on the level of economic development, measured by GDP per capita. Researchers have traditionally associated individualism with high rates of firm creation, arguing that an orientation towards achievement and the pursuit of personal objectives (dominant aspects in individualist cultures) are determinants of entrepreneurial activity. The current analysis shows that a country’s culture correlates to entrepreneurship, but cannot uphold the idea that higher levels of individualism mean higher rates of entrepreneurship. Using data from the Global Entrepreneurship Monitor on 52 countries, the results show that a country’s entrepreneurship rate is negatively related to individualism when development is medium or low, and positively related to individualism when the level of development is high. Thus, individualism is not related to entrepreneurship in the same way in countries with differing levels of development.     

A two-stage sampling by unequal size samples from two normal populations with unknown variances

A two-stage procedure based on the statistic introduced by Scheffé (1943) to solve the Behrens-Fisher problem is considered in estimating the difference between the mean values of two normal distributions having unequal and unknown variances. Samples of unequal size are considered at each stage. A numerical example is given where the two-stage procedure is compared with the Satterthwaite (1946) approximate method.     

Millenials’ intentions to book on Airbnb

ABSTRACT

The sharing economy has witnessed a significant growth in recent years, enhanced by the development of online platforms. In particular, Airbnb has witnessed a significant worldwide year-on-year growth. Given the importance and popularity of Airbnb, it is crucial to examine which factors affect intentions to book on this website. This study proposes and tests a model based on the Theory of Reasoned Action, to examine millennials’ determinants of intentions to book on Airbnb. Based on two online surveys targeting millennials from Germany and China, the results show that intentions to book on Airbnb is mostly influenced by subjective norm, desire for unique accommodation and variety, attitude and economic benefits. Surprisingly, economic benefits have the smallest effect. Perceived risk with the purchase channel was found to have no impact on intentions to book on Airbnb. Managerial implications and theoretical contributions are provided.     

Is your open-innovation successful? The mediating role of a firm's organizational and social context

Open firms are not equally successful. This is because, in order to benefit from external sources of knowledge, firms must be able to absorb such knowledge. The paper outlines a firm's context as a set of organizational and social features, which may be considered absorptive capacity antecedents. It explores the mediating role of such antecedents in the relationship – hitherto insufficiently researched – between the degree of openness and innovative performance. The use of a methodology combining both direct interviews and survey of Italian firms has allowed us to confirm the supposed mediating role. We also identify different modes for companies to open up their innovation process and, for each of them, the antecedents that are consistent with choices regarding the degree of openness.
