Three Corrected Score Tests for Generalized Linear Models with Dispersion Covariates

We develop three corrected score tests for generalized linear models with dispersion covariates, thus generalizing the results of Cordeiro , Ferrari and Paula (1993) and Cribari-Neto and Ferrari (1995) . We present, in matrix notation, general formulae for the coefficients which define the corrected statistics. The formulae only require simple operations on matrices and can be used to obtain analytically closed-form corrections for score test statistics in a variety of special generalized linear models with dispersion covariates. They also have advantages for numerical purposes since our formulae are readily computable using a language supporting numerical linear algebra. Two examples, namely, iid sampling without covariates on the mean or dispersion parameter oand one-way classification models, are given. We also present some simulations where the three corrected tests perform better than the usual score test, the likelihood ratio test and its Bartlett corrected version. Finally, we present a numerical example for a data set discussed by Simonoff and Tsai (1994) .     

Which commercial partners are important for the most recently admitted EU countries?

This paper describes the degree of trade integration inside the European Union (EU) after the fifth enlargement in 2004. To achieve this goal, we build a database of information on trade flows between the new EU countries (EU‐10) and 180 commercial partners in six different sectors from 1999 to 2011. Using the standard gravity model and estimating a difference‐in‐differences specification, we analyze how joining the EU affected the intensity and direction of the EU‐10's trade flows. Our results show that though trade exchanges between the EU‐10 and EU‐15 intensified after 2004, the impact of integration was much more significant to the EU‐10 group.     

Key service innovation drivers in the tourism sector: empirical evidence and managerial implications

This study highlights the importance of market orientation and the use of information and communication technologies (ICT) as determinants of service innovation activity for companies in the tourism sector. In doing so, the study provides a means to classify companies as innovative or not. Using a sample of 100 Spanish firms from different branches of the tourism sector, we confirm and extend prior research. In particular, market orientation??especially a customer orientation??is critical for developing new services that lead to competitive advantages. In addition, ICT have a dual, direct, and indirect influence on service innovation.     

Is China Living a Minsky Moment? Between the “Lender of Last Resort” and the Chinese Shadow Financial System

After Lehman Brothers bankruptcy in 2008, the Central Bank of China (PBOC) created a big 1.8 trillion dollars package to boost the Chinese economy. It was a necessary key measure not only to prop up the economy, but also to try to preserve the two-digit growth of the GDP that existed before the Great Recession. The financial instability of international financial circuits made necessary the involvement of the central bank. Ten years later, China’s debt explosion went up during the financial crisis, from six to twenty-eight trillion dollars between 2007 and 2016. In other words, it went up from 148 to 260 percent of GDP during the same period. The goal of this article is to analyze whether China is living a “Minsky moment” or not, and what its implications are for international financial markets.     

The mix of international banks’ foreign claims: Determinants and implications

We analyze the cross-country determinants and financial stability implications of the mix of international banks’ foreign claims. We distinguish between local claims – extended by host country affiliates – and cross-border claims – booked outside the receiving country. Using data on Italian, Spanish, and US banks’ foreign claims, we find that the share of local claims is driven by restrictions on banking sector openness and by local scale economies/business opportunities. The impact of limits on property rights, entry requirements, start-up and informational costs is less robust. Finally, foreign claim volatility is lower in countries with a larger share of local claims.     

What Are the Characteristics That Software Development Project Team Members Associate With a Good Project Manager?

In this study we investigate what software development project team members consider to be a good project manager. Previous research has been carried out using project manager self‐assessments, other project stakeholder views, or recruiters’ views. This qualitative study used the repertory grid technique to identify the characteristics that project team members associate with a good project manager. This technique has been adopted because of its strength in eliciting personal constructs. Among the 18 characteristics identified, the seven most relevant were classified and compared with previous findings, which reveals differences between the team members’ and project managers’ and other stakeholders’ perceptions. Those findings complement the existing skill set and could be considered when recruiting and training project managers and staffing projects.     

Using sublexical priming to enhance brand name phonetic symbolism effects in young children

We examine whether phonetic symbolism effects are conditional on the development of phonological awareness (an ability to recognize sounds in words). Further, we introduce sublexical priming as a means to enhance phonetic symbolism effects. Across four experiments, we demonstrate that product evaluations, consistent with phonetic symbolism theory, are more (less) likely when a child is older (younger). Specifically, older children who can recognize sounds in words perceive back vowel brand names (e.g., Vopoz) as slower, heavier, larger, smoother, creamier, chewier, and thicker than brand names with front vowel sounds (e.g., Vipiz). In addition, we show that phonetic symbolism effects manifest when younger children (low in phonological awareness) are primed to focus on parts of a word/s, which we term sublexical priming. We present embedded tasks and chunking of brand names as strategic communication techniques that can be implemented as sublexical primes to enhance phonetic symbolism effects in younger children.     

Must we choose? European unemployment, American inequality, and the impact of education and labor market institutions

In the last 15 years, two equilibria have arisen in the advanced world. On the one hand, wage dispersion has widened in those countries where unemployment has remained low (with cyclical variations). On the other hand, wherever income inequality has remained unchanged, unemployment has shot upwards. To account for these distinct patterns, we develop a political–economic model showing that, controlling for the skills of the population, the effects of technological and trade shocks (that have affected OECD nations) that are contingent on the institutional rules in place. Economies with generous unemployment allowances adjust through subsidized unemployment. By contrast, low levels of social protection lead to less unemployment but wider wage dispersion. The level of qualifications of the labor force determines the extent of the adjustment for a given institutional arrangement. We derive, in turn, the institutional structure of each country from the political conditions in place at the time of the shock. The empirical part successfully tests the model for the sample of European regions and US states.     

International diversification gains and home bias in banking

This paper studies international diversification in banking, exploiting a bank-level dataset that covers the operations of 38 global banks and their subsidiaries overseas during 1995–2004. The paper finds that banks with a larger share of assets allocated to subsidiaries in emerging market countries were able to attain higher risk-adjusted returns. These gains were somewhat reduced by the concentration of bank subsidiaries in specific geographical regions, which is typical of the observed international expansion strategies. The paper also finds a substantial home bias in the international allocation of bank assets relative to the results of a mean–variance portfolio optimization model.
