Market impact of international sporting and cultural events

We study market reaction to the announcements of the selected country hosting the Summer and Winter Olympic Games, the World Football Cup, the European Football Cup and World and Specialized Exhibitions. We generalize previous results analyzing a large number and different types of mega-events, evaluate the effects for winning and losing countries, investigate the determinants of the observed market reaction and control for the ex ante probability of a country being a successful bidder. Average abnormal returns measured at the announcement date and around the event are not significantly different from zero. Further, we find no evidence supporting that industries, that a priori were more likely to extract direct benefits from the event, observe positive significant effects. Yet, when we control for anticipation, the stock price reactions around the announcements are significant.

Modelling regulatory change V's volume of trading effects in HSIF and HSI volatility

In an earlier paper, we adopted a bi-variate BEKK–GARCH framework and employed a systematic approach to examine structural breaks in the Hang Seng Index and Index Futures market volatility. Switching dummy variables were included and tested in the variance equations to check for any structural changes in the autoregressive volatility structure due to the events that have taken place in the Hong Kong market surrounding the Asian markets crisis. In this paper, we include measures of daily trading volume from both markets in the estimation. Likelihood ratio tests indicate the switching dummy variables become insignificant and the GARCH effects diminish but remain significant. There is some evidence that the Sequential Arrival of Information Model (SIM) provides a platform to explain these market induced effects when volume of trade is accounted for.

Experts vs. Discounters: Consumer Free Riding and Experts Withholding Advice in Markets for Credence Goods

This paper studies the incentives for credence goods experts to invest effort in diagnosis if effort is both costly and unobservable, and if they face competition by discounters who are not able to perform a diagnosis. The unobservability of diagnosis effort and the credence characteristic of the good induce experts to choose incentive compatible tariff structures. This makes them vulnerable to competition by discounters. We explore the conditions under which honestly diagnosing experts survive competition by discounters; we identify situations in which experts misdiagnose consumers in order to prevent them from free-riding on experts' advice; and we discuss policy options to solve the free-riding consumers–cheating experts problem.

Tariff strategies and small open economies

In this paper we examine the issue of optimal tariffs for a small economy that trades with a large economy. We define ‘small’ and ‘large’ in the sense that the world prices are determined solely by the large country, and, therefore, the small country faces exogenously given world prices. Within this framework it is shown that there exist situations in which the small country has an incentive to behave as a Stackelberg leader by committing itself to a non-zero optimal tariff. Although the small country is unable to directly affect world prices, by pre-committing to a non-zero trade tax it may induce a reduction of the large country's optimal trade tax, thereby indirectly improving its terms of trade and welfare.

Managed fund attributes and performance : Australian evidence

This cross-sectional study goes beyond the traditional performance evaluation of managed funds and extends the literature to consider fund-specific attributes that influence performance. Using a sample of 168 Australian open-ended equity funds, the risk adjusted performance is measured using three alternative evaluation techniques. We find that funds with higher management fees and long fund history have contributed to the underperformance. Along with the traditional attributes identified by the literature, market capitalisation of the security held by the fund is included as a unique attribute with significant results, indicating that funds targeting small capitalisation companies display superior performance.

Age and productivity of academics: A case study of a public university in Malaysia

This study examines the relationship between age and productivity measured based on key performance indicators (KPI) amongst academic staff at Universiti Sains Malaysia (USM). Three models were used in the analysis: linear, quadratic and piece-wise spline. The linear model indicates that age is negatively related to KPI. The quadratic model shows an inverted-U shaped relationship where KPI peaks at age 41 years. The piece-wise spline model indicates academic staff reach the peak of their productivity between ages 46-50 years with another productive age interval between 36-40 years implying 10 golden years when KPI could be harvested fruitfully. There is a significant downtrend in the KPI after 50 years of age. Other factors that have significant influence on KPI are gender, academic rank and discipline. The sub-models show that the influence of age on KPI is more significant amongst academic staff in the arts compared to the science stream. Age influence on KPI is significant amongst female staff but not male staff. We conclude that assessing performance in the workplace with regard to age requires complex methodological engagement and also needs to be based on a wider lens which recognises and includes within the discussion, the intangible and social dimensions of performance.

Firm heterogeneity and lobbying

The structure of protection across sectors is usually interpreted as the result of competition among lobbies to influence politicians, but little attention has been devoted to the importance of individual firms in this process. This paper builds a model incorporating firm heterogeneity into a lobbying setup `a la Grossman and Helpman (1994), in a monopolistic competitive environment. We obtain that increased sectorial dispersion cause a fall in equilibrium tariff provided that the exporter’s cutoff is above the mean of the distribution. Also, higher average productivity brings about a fall in the equilibrium tariff, whereas an increase in export costs cause an increase in the tariff. JEL Classification codes: D43, D7, F12, F13, L11

Mudanças institucionais, receitas cumulativas do governo federal e exportações no Brasil entre 1982 e 2001

Desde o início dos anos oitenta, o governo federal brasileiro passou a substituir a receitas de impostos tradicionais por receita de contribuições sociais (cumulativas) na composição da sua receita total (mudança de gestão). Alega-se que este procedimento é uma conseqüência das regras de compartilhamento estabelecidas (receitas de impostos do governo federal são compartilhadas com estados e municípios enquanto que receitas de contribuição não o são).Existem argumentos na literatura mostrando que este processo de descentralização das receitas teve sua origem na mudança de regime político (militar para democrático), outros com a nova Constituição de 1988 e, por último, outros afirmando que ele só foi possível porque a ineficiência das contribuições foi encoberta pela ineficiência alocativa da inflação. Por outro lado, fatos ocorridos no mesmo período, embora não citados na literatura, poderiam explicar ou ajudar na explicação deste comportamento. Entre eles, a fragmentação do poder executivo a partir de 1989 com a primeira eleição presidencial e/ou o processo de abertura da economia a partir dos anos noventa. Usando a técnica de OLS, observou-se que a Nova Constituição e a abertura da economia explicariam esta mudança de gestão. De qualquer forma, independente do que esteja explicando esta mudança, ela é apontada como altamente prejudicial a competitividade das exportações brasileiras. Existem várias proxies tentando medir este efeito, nenhuma delas considerando uma medida de gestão. Resolvemos realizar esta tentativa. Como tínhamos desconfiança da exogeneidade da variável representativa da abertura da economia no teste anterior, tratamos a questão com o instrumental de séries de tempo. No longo prazo, descobrimos que a mudança de gestão afeta negativamente as exportações e positivamente a abertura da economia por ser menos punitiva com as importações em termos de competitividade (as contribuições incidem apenas na comercialização dos produtos importados).

The Financial Rate of Profit: What Is It, and How Has It Behaved in the United States?

This work contributes to the almost nonexistent literature on the profit rate of the financial sector. It updates the single study to include financial variables to cover the past decade, compares this profit rate to the (almost unpublished) Weisskopf and NIPA financial profit rates, compares the financial and nonfinancial sector rates, and details the procedure to construct the profit rate in the financial sector including relevant financial variables which capitalists consider to make profit-rate decisions.

Program Ações Locais (Local Action) and Citizenship: A Shared Management experience in the Historic Town of São Paulo City

Shared management between businesses, governments and society in the historic town of São Paulo city began concurrently with the growth of nonprofit organizations (NGOs) in the 1990s. The program Ações Locais, coordinated by the NGO Associação Viva o Centro is housed in this context and its mission is to bring together individuals, businesses and local governments for economic, social and political development as to build up the citizenship in that area. This study provides a historical background on formation of Brazilian citizenship and, from that reference, analyzes the performing citizenship in the program Ações Locais. The main conclusion of the analysis identified that the program have been consolidated, despite the enormous quotidian difficulties, especially in the social inclusion actions for the poor. The dilemma about how bring in the excluded segments of the population may indicate a new field of research and future studies.
