Invariant tests in an instrumental variables model with unknown data generating process

In this work we focus on tests for the parameter of an endogenous variable in a weakly identi ed instrumental variable regressionmodel. We propose a new unbiasedness restriction for weighted average power (WAP) tests introduced by Moreira and Moreira (2013). This new boundary condition is motivated by the score e ciency under strong identi cation. It allows reducing computational costs of WAP tests by replacing the strongly unbiased condition. This latter restriction imposes, under the null hypothesis, the test to be uncorrelated to a given statistic with dimension given by the number of instruments. The new proposed boundary condition only imposes the test to be uncorrelated to a linear combination of the statistic. WAP tests under both restrictions to perform similarly numerically. We apply the di erent tests discussed to an empirical example. Using data from Yogo (2004), we assess the e ect of weak instruments on the estimation of the elasticity of inter-temporal substitution of a CCAPM model.

Política cultural audiovisual sob o prisma do mecanismo de investimento reembolsável da RioFilme

O presente trabalho busca analisar o resultado da restituição das receitas investidas nos projetos audiovisuais pela empresa RioFilme, no período de 2009 a 2013, por meio do mecanismo de investimento reembolsável, visando identificar a possibilidade de retroalimentação para novos investimentos. A RioFilme, que é uma empresa pública de investimentos em audiovisual da Prefeitura do Rio de Janeiro, realiza investimentos reembolsáveis, nos quais adquire participação nas receitas dos projetos; e não reembolsáveis, em que não há possibilidade restituição financeira para a empresa. Para a operacionalização da pesquisa foi realizada a análise documental de 79 processos administrativos e extraídos dados dos investimentos financeiros realizados RioFilme no setor audiovisual carioca no período de 2009 a 2013. O setor audiovisual brasileiro possui grande intervenção governamental, seja ela de forma direta, como também indireta, através das leis de incentivo à cultura, que utilizam a renúncia fiscal. Este modelo não traz restituição direta para o ente estatal, e consequentemente não possibilita a retroalimentação financeira do Estado para novos investimentos. Desta forma, a análise dos modelos alternativos de financiamento do setor audiovisual, como o mecanismo reembolsável utilizado pela RioFilme é de suma importância para a política cultural audiovisual brasileira, tendo em vista que neste modelo de investimento utilizado pela mesma há possibilidade de restituição financeira direta, possibilitando sua retroalimentação para investimentos em novas obras audiovisuais.

On paternalistic leadership fit: exploring cross-cultural endorsement, leader-follower fit, and the boundary role of organizational culture

Although cross-cultural leadership research has thrived in international business literature, little attention has been devoted to understanding the effectiveness of non-western theories beyond their original contexts. The purpose of this study is to examine the cross-cultural endorsement of paternalistic leadership, an emerging non-western leadership theory, using data from GLOBE project. Using multigroup confirmatory factor analyses we found measurement equivalence of a scale derived from GLOBE’s data, which enabled us to compare the endorsement of paternalistic leadership dimensions across 10 cultural clusters and 55 societies. Our study revealed that there are significant differences in the importance societies give to each dimension, suggesting that paternalism as leadership style is not universally nor homogeneously endorsed. Furthermore, results suggest that different patterns of endorsement of each of these dimensions give rise to idiosyncratic shades of paternalistic leadership across societies. Implications for theory and future research on international business are discussed.

An analysis of the perceived service quality of hospitality industry in Rio de Janeiro through the SERVQUAL model: a multiple case study

Brazil is under political and financial crises where the end seems far away. Because of that, researchers argue that the hotel rooms offered by Rio de Janeiro, built to host the Olympic Games 2016, will be difficult to occupy after the event. It is then necessary for the hotels to understand how guests perceive the service quality in order to adapt to this new era. If guests’ perceptions meet or exceed their expectations, they will be satisfied and will probably return. Thus based on the SERVQUAL approach, this paper aims to study the impact of the service dimensions on the guests’ overall satisfaction at hotels of Rio de Janeiro. Two hotels were considered representative of the city in terms of service quality and customers’ profile. Interviews to the hotel managers were performed, and questionnaires to the guests were administered. Among the five SERVQUAL dimensions – Reliability, Tangibles, Responsiveness, Assurance, and Empathy – the Empathy dimension appears to be the only one that affects the guests’ overall satisfaction. The study could also identify that gender, country of residence, home country and family income have an impact on guests’ satisfaction. This study has no intention of generalization, but rather of refining the theory about services and the SERVQUAL model.
