Leverage, Volatile Future Earnings Growth and Expected Stock Returns

We provide theory and evidence to complement Choi's [RFS, 2013] important new insights on the returns to equity in `value' firms. We show that higher future earnings growth ameliorates the value-reducing effect of leverage and, because the market for earnings is incomplete, reduces the earnings-risk sensitivity of the default option. Ceteris paribus, a levered firm with low (high) earnings growth is more sensitive to the first (second) of these effects thus generating higher (lower) expected returns. We demonstrate this by modeling equity as an Asian-style call option on net earnings and find significant empirical support for our hypotheses.

Do Colombian students underestimate higher education returns?

We analyze the determinants of subjective returns of higher education in Colombia. The information on expectations has been collected in categories, motivating the use of interval regression and an ordered probit approaches for modeling the relationship between beliefs and measures of ability, conditioning on individual, school and regional covariates. The results suggest that there are considerable differences in the size of the expected returns according to some population groups and a strong dominance of college against technical education. Gender gaps disappear in college education but it is found that girls tend to believe that professional wages are more concentrated into higher income categories than boys. Finally, it seems that Colombian students overestimate the pecuniary returns to education.

Comovement in UK real estate sector returns

Engle et al. (1990) distinguish between 'heat waves' and 'meteor showers' in an analogy which tries to differentiate between particular effects, not transmitted among markets, and general effects, which tend to affect all the markets, although different markets can be affected to different degrees. This paper applies this approach to the study of the monthly returns of four real estate market sectors: Office, Retail, Industrial and Retail Warehouses in the UK over the period 1979:2 to 1997:12. A VAR methodology used with the aim of detecting the causal relations and dynamic interactions among sector returns, as well as the transmission mechanisms of their information flows. The results obtained permit us to conclude that there is a good deal of integration between the monthly return time series for all the sectors. Therefore, diversification across real estate market sectors does not allow for the reduction of risk without sacrificing expected returns.

The future returns for property required by UK pension funds

In the 1970s Real Estate represented over 17% of the average pension funds total assets. Today such funds hold less than 4%, a figure not seen since the 1960s. This reduction in Real Estate holdings is mainly attributable to the relatively poor performance of Real Estate against other asset classes since the 1980s. Whether pension funds will increase their holding at any point in the future depends therefore on the expected return of Real Estate by comparison with that required to justify a particular asset holding. Using the technique of Modern Portfolio Theory (MPT), this paper assesses the required return that Real Estate would have to offer to justify a 15% holding in a mixed asset portfolio. This figure and the risk/return characteristics of the major asset classes is taken from survey data. Under a number of scenarios it is found that Real Estate can play a part in a mixed asset portfolio at the 15% level. In some cases however, the expected returns of Real Estate are not sufficient to justify a weight of 15% in this asset.

Predictable dividends and returns

The conventional wisdom is that the aggregate stock price is predictable by the lagged pricedividend ratio, and that aggregate dividends follow approximately a random-walk. Contrary to this belief, this paper finds that variation in the aggregate dividends and price-dividend ratio is related to changes in expected dividend growth. The inclusion of labor income in a cointegrated vector autoregression with prices and dividends allows the identification of predictable variation in dividends. Most of the variation in the price-dividend ratio is due to changes in expected returns, but this paper shows that part of variation is related to transitory dividend growth shocks. Moreover, most of the variation in dividend growth can be attributed to these temporary changes in dividends. I also show that the price-dividend ratio (or dividend yield) can be constructed as the sum of two distinct, but correlated, variables that separately predict dividend growth and returns. One of these components, which could be called the expected return state variable, predicts returns better than the price-dividend ratio does.

Consumption habit and international stock returns

We use the consumption-based asset pricing model with habit formation to study the predictability and cross-section of returns from the international equity markets. We find that the predictability of returns from many developed countries' equity markets is explained in part by changing prices of risks associated with consumption relative to habit at the world as well as local levels. We also provide an exploratory investigation of the cross-sectional implications of the model under the complete world market integration hypothesis and find that the model performs mildly better than the traditional consumption-based model. the unconditional and conditional world CAPMs and a three-factor international asset pricing model.

Forecasting stock returns using model-selection criteria

This paper examines the economic significance of return predictability in Australian equities. In light of considerable model uncertainty, formal model-selection criteria are used to choose a specification for the predictive model. A portfolio-switching strategy is implemented according to model predictions. Relative to a buy-and-hold market investment, the returns to the portfolio-switching strategy are impressive under several model-selection criteria, even after accounting for transaction costs. However, as these findings are not robust across other model-selection criteria examined, it is difficult to conclude that the degree of return predictability is economically significant.

Serial correlation in the returns of UK capitalization based portfolios

This article examines whether UK portfolio returns are time varying so that expected returns follow an AR(1) process as proposed by Conrad and Kaul for the USA. It explores this hypothesis for four portfolios that have been formed on the basis of market capitalization. The portfolio returns are modelled using a kalman filter signal extraction model in which the unobservable expected return is the state variable and is allowed to evolve as a stationary first order autoregressive process. It finds that this model is a good representation of returns and can account for most of the autocorrelation present in observed portfolio returns. This study concludes that UK portfolio returns are time varying and the nature of the time variation appears to introduce a substantial amount of autocorrelation to portfolio returns. Like Conrad and Kaul if finds a link between the extent to which portfolio returns are time varying and the size of firms within a portfolio but not the monotonic one found for the USA.

A teoria dos custos de transação e as relações contratuais entre cooperativas e clientes : uma contribuição para o entendimento do sistema cooperativista da agropecuária do Espírito Santo

O principal objetivo desta Dissertação é estudar como são estabelecidas as relações contratuais entre as cooperativas agropecuárias do Espírito Santo e como estas relações permitem reduzir os custos de transação. A motivação básica, portanto, é contribuir para que as cooperativas voltadas para este ramo possam melhor estruturar a governança de suas transações. Para atingir estes objetivos, a base teórica que apóia este trabalho é discutida em uma revisão de literatura da Teoria dos Custos de Transação, abordando seus princípios teóricos. Outra investigação importante para o debate a ser realizado neste estudo refere-se ao surgimento do sistema cooperativista, seu conceito e sua forma de funcionamento. A conexão estabelecida entre estes dois temas é considerada importante para entender a natureza das cooperativas, principalmente em seu conceito de firma (ou instituição) que busca organizar as trocas (de bens e/ou serviços) de maneira eficiente. O estudo busca, portanto, compreender quais estruturas estas associações adotam para realizar suas transações, propondo estruturas alternativas que permitam reduzir os custos de transação de forma eficiente e aumentar o retorno esperado pelos produtores, de acordo com as propostas da teoria. O estudo revela que o comportamento de diversas cooperativas é diferente do proposto pela TCT. Em alguns desses casos, isto impede que elas reduzam os custos de transação da forma mais eficiente possível. Em outros, no entanto, as práticas que colidem com o proposto na TCT (por motivos idiossincráticos, institucionais e/ou estruturais próprios da organização) podem trazer resultados auspiciosos para as cooperativas.

Urban containment: An effective tool for environmental protection?

This paper examines the effectiveness of urban containment policies to protect forestland from residential conversion and to increase the provision of forest public goods in the presence of irreversible investments and policy uncertainty. We develop a model of a single landowner that allows for switching between competing land uses (forestry and residential use) at some point in the future. Our results show that urban containment policies can protect (even if temporarily) forestland from being developed but must be supplemented with policies that influence the length and number of harvesting cycles if the goal is to increase nontimber benefits. The threat of a development prohibition creates incentives for preemptive timber harvesting and land conversion. In particular, threatened regulation creates an incentive to shorten rotation cycles to avoid costly land-use restrictions. However, it has an ambiguous effect on forestland conversion as the number of rotation cycles can also be adjusted to maximize the expected returns to land. Finally, in the presence of irreversibility, forestland conversion decisions should be done using real option theory rather than net present value analysis
