We provide a comparison of bidding behavior between multi-round and single-round auctions considering bid lettings for asphalt construction contracts that are known to have primarily private costs. Using a reduced-form difference-in-difference approach as well as the nonparametric estimation technique that was proposed by Racine and Li (J Econom 119(1):99–130, 2004) we find that bidding is more aggressive in a sequential multi-round setting than in a simultaneous single-round format. We explore potential causes for the bidding difference across formats that are related to synergies and the level of bidder participation.  相似文献

From December 1999, shareholders who disposed of shares in Australian takeovers in exchange for scrip could elect to defer capital gains taxation until the disposal of the shares received. We investigate payment method choice by acquiring firms before and after this regulatory change to assess whether target shareholder capital gains tax liabilities became an important factor considered in choosing the form of payment. The results show that, subsequent to the regulatory change, there is a significantly higher probability that equity will be offered as consideration where target shareholder capital gains are greater. This finding confirms the importance of shareholder level taxation in explaining corporate acquisition structure and adds to previous European and US evidence on factors associated with payment method choice in takeovers.  相似文献

We compute the value of fiscal multipliers (for government primary expenditure, Income and wealth taxes and for Production and import taxes) in the Eurozone countries since the creation of the currency union (2000Q1-2016Q4), in order to understand how the values can vary according to the public debt level, the pace of economic growth, and the output gap. Imposing quarterly fiscal shocks, the results showed that government expenditure had a positive effect on output, with an annual accumulated multiplier of 0.44, whereas tax multipliers presented negative signs: the Income and wealth and the Production and import taxes stood at ?0.11 and ?0.55, respectively. Furthermore, the spending multiplier showed a higher value for countries with lower levels of public debt, during recessions, and in countries with negative output gaps. On the other hand, tax shocks seemed to be recessive in highly indebted countries and those facing positive output gaps.  相似文献

ABSTRACT

This paper analyzes the relationship between withdrawals from Brazilian open retirement funds, portfolio composition (fixed income or equity) and frequency of statement sending (monthly, quarterly, semiannually or annually). Our results indicate that equity retirement plans present a lower withdrawal index when compared to that of fixed income plans. Furthermore, the higher the statement sending frequency, the lower the withdrawals from open retirement plans. However, withdrawals from equity retirement plans tend to increase when statements are sent to investors more frequently. These phenomena can be explained by behaviorist theories, such as the concept of myopic loss aversion. In a context where loss aversion is present, the more frequently the investor evaluates his or her portfolio, or the shorter the investment horizon, the less attractive he or she will find investment in assets with a high rate of return and risk, such as equities. This behavior occurs not only regarding short-term investments, but also traditional long-term assets such as equity retirement plans.

RESUMEN. Este estudio analiza la relación existente entre las retiradas de los fondos abiertos de jubilación brasileños, la composición de la cartera (ingreso fijo o patrimonio), y la frecuencia del envío de estados financieros (mensual, trimestral, semestral o anualmente). Nuestros resultados indican que los planes de jubilación patrimonial tienen un índice de retirada menor, en comparación con los planes de ingreso fijo. Además, cuanto mayor la frecuencia de los estados financieros, menor es la retirada de los planes abiertos de jubilación. Sin embargo, las retiradas de los planes de jubilación patrimoniales tienden a aumentar cuando los estados se envían a los inversores con más frecuencia. Este fenómeno puede explicarse con las teorías comportamentales, tales como el concepto de la aversión miope a la pérdida. En un contexto donde la aversión a la pérdida es una realidad, cuanto mayor la frecuencia con que el inversor pueda evaluar su carera, o menor el horizonte de inversión, menos atractivas considerará él las inversiones en activos con un alto retorno y riesgo, tal como las acciones. Este comportamiento ocurre no sólo en las inversiones a corto plazo, sino también en los activos a largo plazo, como los planes de jubilación patrimoniales.

RESUMO. Este artigo analisa a relação entre as retiradas dos fundos abertos de aposentadoria brasileiros, a composição da carteira (renda fixa ou ações) e a freqüência da remessa de extratos (mensal, trimestral ou semestral). Nossos resultados indicam que os planos de aposentadoria que aplicam em ações apresentam um índice de retirada menor em comparação com os planos de renda fixa. Além disso, quanto maior a freqüência de remessa de extratos, menores as retiradas dos planos abertos de aposentadoria. Entretanto, as retiradas dos planos de aposentadoria que aplicam em ações tendem a aumentar quando o extrato é enviado aos investidores commais freqüência. Esses fenômenos podem ser explicados por teorias behavioristas, como o conceito de aversão míope à perda. Num contexto onde a aversão à perda esteja presente, quanto maior a freqüência com que o investidor avalia a sua carteira, ou quanto menor o horizonte do investimento, menos atraente ele achará o investimento em ativos com alto retorno e risco, como ações. Esse comportamento ocorre não apenas em investimentos a curto prazo, mas também nos ativos tradicionais de longo prazo como os planos de aposentadoria com aplicação em ações.  相似文献

The main objective of this research was to investigate the impacts caused by announcements of mergers and acquisitions (M&As) on the volatility of the returns of Brazilian bank stocks from 1994 to 2015. In order to achieve the proposed objective, this study applied Generalized Autoregressive Conditional Heteroscedastic (GARCH) class models to the series to model their volatility. Our results confirmed the impact of the announcement of M&As on volatility. They suggest that M&A announcements are expected to cause a negative reaction if related to an expansion or a deal involving a less-well known bank, and a positive reaction if it involves well-known bank with good reputation—a higher level of confidence and a lower level of information asymmetry for investors.  相似文献

ABSTRACT

This article analyzes what influences a firm's choice of strategy—why some firms stick to defensive strategies while others rely on offensive ones. With this in mind a survey was conducted on mineral sector companies associated with the Brazilian Mining Institute. The results show that the majority of companies use an offensive strategy and that some companies use more than one strategy at the same time. That is, they possess a corporate strategy and a sustainability strategy.  相似文献

Performance measurement of police services is complicated by ambiguous and complex goaland objectives-setting, and by the difficulties of measuring outputs. This article looks at the organizational and management changes being made in Portuguese police forces. The authors fill a gap in the literature on performance measurement in Portugal by taking a national approach to the study of how law enforcement agencies are introducing new management accounting changes. The article therefore widens the debate on performance measurement and performance improvements in law enforcement.  相似文献

ABSTRACT

Portugal and Spain have reformed their national standards to adapt them to the International Public Sector Accounting Standards (IPSAS). This paper explains the process of implementing the IPSAS for consolidated reporting in the two countries and the advantages and disadvantages which have emerged. The results highlight the role of the IPSAS in improving the quality and use of consolidated financial statements (CFS) and will be of interest to other countries that are intending to implement the IPSAS.  相似文献

This cross-sectional study of Portuguese service organizations seeks to determine the level of alignment of competitive methods with strategy typologies covered in the business literature. Surveyed firms were asked to indicate their level of utilization of several competitive methods. The results of factor analysis of the survey data indicate that 30 of the 33 competitive methods covered in this study represent seven underlying strategy dimensions. Further analysis revealed that there is some congruence between the derived strategy dimensions and established strategy typologies in the literature. Cluster analysis revealed that each of the responding firms could be classified into one of four hybrid or mixed strategy orientations. However, differences in strategy orientation were not statistically significant in explaining differences in the financial performance of these organizations. These findings are discussed in the light of their implications for strategy development, strategy choices and performance evaluation in the Portuguese service sector.  相似文献

Using quantile regressions, this paper examines the possibility of significant nonlinear relationships between the profitability of Portuguese service small- and medium-sized enterprises (SMEs) and its specific determinants. The results lead to the conclusion that there is a significant nonlinearity between specific determinants and profitability in Portuguese service SMEs. In the lower quantiles of the distribution of profitability of Portuguese SMEs, it is found that profitability on the one hand is catalysed by size, long-term debt and managerial control, and on the other hand, it is restricted by risk and research and development intensity. In the upper quantiles of the profitability distribution of Portuguese service SMEs, liquidity and research and development intensity serve as catalysers of profitability, while long-term debt restricts the level of profitability.  相似文献
