A influência da alavancagem financeira na construção do custo de capital próprio: um estudo voltado para o mercado brasileiro

No contexto do Capital Asset Pricing Model (CAPM), este trabalho investiga a significância da alavancagem financeira na construção do risco sistemático. Testamos com dados brasileiros o procedimento de desalavancagem e realavancagem do beta comumente realizado por analistas financeiros para a construção do custo de capital próprio de empresas não negociadas em bolsa de valores. Os resultados apontam que a inclusão do tax shield na fórmula de desalavancagem/realavancagem e a utilização de valores de mercado produzem resultados mais robustos, ao passo que as divisões por setores possuem pouca capacidade como segmentadores de classe de risco sistemático.

Mitigating high ‘equity capital’ risk exposure to ‘small cap’ sector in India: analysing ‘key factors of success’ for ‘Institutional Investors’ whilst Investing in small cap sector in India

This paper deals with the subject of mitigating high ‘Equity Capital’ Risk Exposure to ‘Small Cap’ Sector in India. Institutional investors in India are prone to be risk averse when it comes to investing in the small cap sector in India as they find the companies risky and volatile. This paper will help analyse ‘Key Factors of success’ for ‘Institutional Investors’ whilst investing in Small Cap sector in India as some of these Indian small cap stocks offer handsome returns despite economic downturn. This paper has been harnessed carefully under the influence of expert investors, which includes Benjamin Graham (Security Analysis); Warren Buffet; Philip Fisher (Common Stocks and Uncommon Profits); and Aswath Damodaran.

Impacto da responsabilidade social empresarial no custo de capital próprio das empresas brasileiras: um estudo empírico do período de 2005 a 2009

Assim como a literatura existente sobre o impacto do investimento social empresarial na performance financeira da empresa, esse estudo tem o objetivo de analisar o efeito da responsabilidade social empresarial no custo de capital próprio das empresas. Foi estimado o custo de capital próprio das empresas do Índice da Bolsa de Valores de São Paulo – Ibovespa, representativo do mercado e das empresas participantes da carteira do ISE, representativa da responsabilidade social corporativa, para o período de 2005 a 2009. Como resultado, notou-se que, na maioria dos anos estudados, não foi significativa a queda no custo de capital próprio das empresas que fazem parte do ISE, apontando para o fato de o investimento em responsabilidade social empresarial não afetar indicadores financeiros como o custo de capital próprio analisado.

The welfare cost of macroeconomic uncertainty in the post-war period

Lucas (1987) has shown the surprising result that the welfare cost of business cycles is quite small. Using standard assumptions on preferences and a fully-áedged econometric model we computed the welfare costs of macroeconomic uncertainty for the post-WWII era using the multivariate Beveridge-Nelson decomposition for trends and cycles, which considers not only business-cycle uncertainty but also uncertainty from the stochastic trend in consumption. The post-WWII period is relatively quiet, with the welfare costs of uncertainty being about 0:9% of per-capita consumption. Although changing the decomposition method changed substantially initial results, the welfare cost of uncertainty is qualitatively small in the post-WWII era - about $175.00 a year per-capita in the U.S. We also computed the marginal welfare cost of macroeconomic uncertainty using this same technique. It is about twice as large as the welfare cost ñ$350.00 a year per-capita.

An ordering of measures of the welfare cost of inflation in economies with interest-bearing deposits

This paper builds on Lucas (2000) and on Cysne (2003) to derive and order six alternative measures of the welfare costs of inflation (five of which already existing in the literature) for any vector of opportunity costs. The ordering of the functions is carried out for economies with or without interestbearing deposits. We provide examples and closed-form solutions for the log-log money demand both in the unidimensional and in the multidimensional setting (when interest-bearing monies are present). An estimate of the maximum relative error a researcher can incur when using any particular measure is also provided.

The risk-properties of human capital and the design of government policies

Whether human capital increases or decreases wage uncertainty is an open question from an empirical standpoint. Yet, most policy prescriptions regarding human capital formation are based on models that impose riskiness on this type of investment. In a two period and finite type optimal income taxation problem we derive prescriptions that are robust to the risk characteristics of human capital: savings should be discouraged, human capital investments encouraged and both types of investment driven to an efficient level from an aggregate perspective. These prescriptions are also robust to the assumptions regarding what choices are observed, despite policy instruments being not.

The impact of public capital and public investment on economic growth: an empirical investigation

in this anicle we measure the impact of public sector capital and investment on economic growth. Initially, traditional growth accounting regressions are run for a cross-country data set. A simple endogenous growth model is then constructed in order to take into account the determinants of labor, private capital and public capital. In both cases, public capital is a separate argument of the production function. An additional data-set constructed with quarterly American data was used in the estimations of the growth mode!. The results indicate lhat public capital and public investment play a significant role in determining growth rates and have a significant impact on capital and labor returns. Furthermore, the impact of public investment on productivity growth was found to be positive and always significant for bolh samples. Hence. in a fully optimizing modelo we confmn previous results in the literature that lhe failure of public investment to keep pace with output growlh during the Seventies and Eighties may have played a major role in the slowdown of lhe productivity growth in the period. Anolher main outcome concems the output elasticity wilh respect to public capital. The coefficiem estimates are always positive and significant but magnitudes depend on each of lhe two data set used.

The welfare cost of macroeconomic uncertainty in the post-war period

With standard assumptions on preferences and a fully-fledged econometric model we computed the welfare costs of macroeconomic uncertainty for post-war U.S. using the BeveridgeNelson decomposition. Welfare costs are about 0.9% per-capita consumption ($175.00) and marginal welfare costs are about twice as large.

Predictability of equity models

In this study, we verify the existence of predictability in the Brazilian equity market. Unlike other studies in the same sense, which evaluate original series for each stock, we evaluate synthetic series created on the basis of linear models of stocks. Following Burgess (1999), we use the “stepwise regression” model for the formation of models of each stock. We then use the variance ratio profile together with a Monte Carlo simulation for the selection of models with potential predictability. Unlike Burgess (1999), we carry out White’s Reality Check (2000) in order to verify the existence of positive returns for the period outside the sample. We use the strategies proposed by Sullivan, Timmermann & White (1999) and Hsu & Kuan (2005) amounting to 26,410 simulated strategies. Finally, using the bootstrap methodology, with 1,000 simulations, we find strong evidence of predictability in the models, including transaction costs.

Underpricing of equity offerings in Brazil

We examine the underpricing of twenty-seven IPOs and twenty-nine SEOs issued in Brazil from January 1999 to March 2006. Determinants on pre-market demand, underwriting activities and information asymmetry were discussed. Common characteristics seem to exist between all issues. 94% have been on premium market corporate level and 93% were realized via bookbuilding. Underpricing for IPOs and SEOs has been recorded at 9.6% and 3.6%, respectively. IPOs are more underpriced when (i) more informed investors receive shares, (ii)better ranked underwriters lead the offer, and (iii) there is positive revision in the final price compared to the initial price range defined before information disclosure. SEOs are more underpriced when (i) shares presents higher appreciation in pre-offer period, and (ii) the proportion of primary offers are larger, supporting adverse selection costs theory.

Measures of the welfare cost of inflation: a complete ordering

This paper presents three contributions to the literature on the welfare cost of ináation. First, it introduces a new sensible way of measuring this cost - that of a compensating variation in consumption or income, instead of the equivalent variation notion that has been extensively used in empirical and theoretical research during the past fiftt years. We Önd this new measure to be interestingly related to the proxy measure of the shopping-time welfare cost of ináation introduced by Simonsen and Cysne (2001). Secondly, it discusses for which money-demand functions this and the shopping-time measure can be evaluated in an economically meaningful way. And, last but not least, it completely orders a comprehensive set of measures of the welfare cost of ináation for these money-demand specification. All of our results are extended to an economy in which there are many types of monies present, and are illustrated with the log-log money-demand specification.

O BNDES gera lucro econômico? : utilização da metodologia do EVA® para verificar a criação de valor ao acionista

O objetivo deste trabalho foi verificar se o BNDES, no período entre 2000 e 2011 gerou lucro econômico para o seu principal acionista, o Governo Federal. Foram analisados demonstrativos financeiros e notas explicativas publicadas neste período para obtenção de dados para o cálculo do Valor Econômico Adicionado ou Economic Value added (EVA®). Esta metodologia deduz o custo de todo o capital empregado na empresa do lucro operacional após os impostos. Além disso, utiliza o custo médio ponderado de capital (CMPC) ou Weighted Average Cost of Capital (WACC) como taxa de remuneração do capital investido para cálculo do custo do capital. O WACC pondera o custo de capital de terceiros, após a dedução da alíquota dos impostos incidentes sobre o lucro e o custo de capital próprio. A utilização de algumas premissas e a elaboração de alguns cenários foram necessários para a estimativa do custo do capital próprio do acionista. Além disso, alguns ajustes, como a inclusão de dividendos e juros sobre capital próprio pagos pelo BNDES ao acionista foram realizados para o cálculo do EVA®, além de outros ajustes contábeis necessários. Ao final do estudo, observamos que, em todos os cenários utilizados, a geração de lucro econômico foi negativa.

Financial disruption as a cost of sovereign default

This dissertation analyses quantitatively the costs of sovereign default for the economy, in a model where banks with long positions in government debt play a central role in the financial intermediation for private sector's investments and face financial frictions that limit their leverage ability. Calibration tries to resemble some features of the Eurozone, where discussions about bailout schemes and default risk have been central issues. Results show that the model captures one important cost of default pointed out by empirical and theoretical literature on debt crises, namely the fall in investment that follows haircut episodes, what can be explained by a worsening in banks' balance sheet conditions that limits credit for the private sector and raises their funding costs. The cost in terms of output decrease is though not significant enough to justify the existence of debt markets and the government incentives for debt repayment. Assuming that the government is able to alleviate its constrained budget by imposing a restructuring on debt repayment profile that allows it to cut taxes, our model generates an important difference for output path comparing lump-sum taxes and distortionary. For our calibration, quantitative results show that in terms of output and utility, it is possible that the effect on the labour supply response generated by tax cuts dominates investment drop caused by credit crunch on financial markets. We however abstract from default costs associated to the breaking of existing contracts, external sanctions and risk spillovers between countries, that might also be relevant in addition to financial disruption effects. Besides, there exist considerable trade-offs for short and long run path of economic variables related to government and banks' behaviour.
