Depreciation and its impact on the total return of UK commercial real estate, 1994-2003

Depreciation is a key element of understanding the returns from and price of commercial real estate. Understanding its impact is important for asset allocation models and asset management decisions. It is a key input into well-constructed pricing models and its impact on indices of commercial real estate prices needs to be recognised. There have been a number of previous studies of the impact of depreciation on real estate, particularly in the UK. Law (2004) analysed all of these studies and found that the seemingly consistent results were an illusion as they all used a variety of measurement methods and data. In addition, none of these studies examined impact on total returns; they examined either rental value depreciation alone or rental and capital value depreciation. This study seeks to rectify this omission, adopting the best practice measurement framework set out by Law (2004). Using individual property data from the UK Investment Property Databank for the 10-year period between 1994 and 2003, rental and capital depreciation, capital expenditure rates, and total return series for the data sample and for a benchmark are calculated for 10 market segments. The results are complicated by the period of analysis which started in the aftermath of the major UK real estate recession of the early 1990s, but they give important insights into the impact of depreciation in different segments of the UK real estate investment market.

Real option pricing in mixed-use development projects

The application of real options theory to commercial real estate has developed rapidly during the last 15 Years. In particular, several pricing models have been applied to value real options embedded in development projects. In this study we use a case study of a mixed use development scheme and identify the major implied and explicit real options available to the developer. We offer the perspective of a real market application by exploring different binomial models and the associated methods of estimating the crucial parameter of volatility. We include simple binomial lattices, quadranomial lattices and demonstrate the sensitivity of the results to the choice of inputs and method.

Pricing short leases and break clauses using simulation methodology

This paper examines the changes in the length of commercial property leases over the last decade and presents an analysis of the consequent investment and occupational pricing implications for commercial property investmentsIt is argued that the pricing implications of a short lease to an investor are contingent upon the expected costs of the letting termination to the investor, the probability that the letting will be terminated and the volatility of rental values.The paper examines the key factors influencing these variables and presents a framework for incorporating their effects into pricing models.Approaches to their valuation derived from option pricing are critically assessed. It is argued that such models also tend to neglect the price effects of specific risk factors such as tenant circumstances and the terms of break clause. Specific risk factors have a significant bearing on the probability of letting termination and on the level of the resultant financial losses. The merits of a simulation methododology are examined for rental and capital valuations of short leases and properties with break clauses.It is concluded that in addition to the rigour of its internal logic, the success of any methodology is predicated upon the accuracy of the inputs.The lack of reliable data on patterns in, and incidence of, lease termination and the lack of reliable time series of historic property performance limit the efficacy of financial models.

Pricing and hedging short sterling options using artificial neural networks

This paper compares the performance of artificial neural networks (ANNs) with that of the modified Black model in both pricing and hedging Short Sterling options. Using high frequency data, standard and hybrid ANNs are trained to generate option prices. The hybrid ANN is significantly superior to both the modified Black model and the standard ANN in pricing call and put options. Hedge ratios for hedging Short Sterling options positions using Short Sterling futures are produced using the standard and hybrid ANN pricing models, the modified Black model, and also standard and hybrid ANNs trained directly on the hedge ratios. The performance of hedge ratios from ANNs directly trained on actual hedge ratios is significantly superior to those based on a pricing model, and to the modified Black model.

Corporate capital structure revisited: incomplete markets and default

After Modigliani and Miller (1958) presented their capital structure irrelevance proposition, analysis of corporate Önancing choices involving debt and equity instruments have generally followed two trends in the literature, where models either incorporate informational asymmetries or introduce tax beneÖts in order to explain optimal capital structure determination (Myers, 2002). None of these features is present in this paper, which develops an asset pricing model with the purpose of providing a positive theory of corporate capital structure by replicating main aspects of standard contractual practice observed in real markets. Alternatively, the imperfect market structure of the economy is tailored to match what is most common in corporate reality. Allowance for default on corporate debt with an associated penalty of seizure of Örmís future cash áows by creditors is introduced, for instance. In this context, a qualitative assessment of Önancial managersídecisions is carried out through numerical procedures.

Estimando a aversão ao risco, a taxa de desconto intertemporal, e a substutibilidade intertemporal do consumo no Brasil usando três tipos de função utilidade

Nesse trabalho estima-se, usando o método generalizado dos momentos e dados brasileiros, os parâmetros estruturais do modelo CCAPM (consumption capital asset pricing model) a partir de três classes de funções utilidade distintas: função utilidade potência (CRRA), utilidade com hábito externo, e aversão ao desapontamento (Kreps-Porteus). Estes parâmetros estruturais estão associados à aversão ao risco, à elasticidade de substituição intertemporal no consumo e à taxa de desconto intertemporal da utilidade futura. Os resultados aqui obtidos são analisados e comparados com resultados anteriores para dados brasileiros e americanos. Adicionalmente, testa-se econometricamente todos os modelos estruturais estimados a partir do teste de restrições de sobre-identificação, para investigar, da forma mais abrangente possível, se há ou não equity premium puzzle para o Brasil. Os resultados surpreendem, dado que, em raríssimas ocasiões, se rejeita as restrições implícitas nesses modelos. Logo, conclui-se que não há equity premium puzzle para o Brasil.

Posição de caixa e o retorno das ações no mercado acionário brasileiro, 1994-2009

Este trabalho busca, através dos princípios de Finanças Corporativas e de Apreçamento de Ativos, mensurar o impacto do nível de liquidez das companhias na expectativa de retorno das ações no mercado acionário brasileiro. O pressuposto básico dessa relação é que a posição de caixa representa um tipo de risco não capturado por outras variáveis. Para mensurar esse risco, será utilizada a modelagem de fatores para apreçamento de ativos. O modelo básico utilizado será o de três fatores de Fama e French, adaptado para a inclusão da variável caixa. A partir da base de dados, se tentará estimar a sensibilidade do retorno esperado das ações brasileiras ao fator caixa.

Crescimento do consumo e a estrutura a termo de taxa de juros: um estudo voltado para o caso brasileiro

Tendo por base o trabalho realizado por Hyde e Sherif (2010) com dados do mercado inglês, foi desenvolvido estudo com o objetivo de avaliar a capacidade do spread de curto e longo prazo da taxa de juros de funcionar como indicador do crescimento futuro do consumo no Brasil. Tanto Hyde e Sherif (2010) como outros estudos realizados em países desenvolvidos indicaram relação positiva entre o spread de juros de curto e longo prazo e o crescimento do consumo. Entretanto, as análises empíricas realizadas neste estudo para o caso brasileiro, apresentaram resultados divergentes do esperado pela teoria, indicando relação negativa entre o spread de juros e o crescimento do consumo. Em algumas análises, os estudos não indicaram relação entre as variáveis. Foram discutidas possíveis razões para estes resultados contraintuitivos, tais como tamanho reduzido da amostra, nível da taxa de juros no Brasil e liquidez do mercado futuro de juros. Adicionalmente foram analisados os modelos teóricos C-CAPM (Consumption-based asset pricing model) e o modelo de consumo habitual desenvolvido por Campbell e Cochrane (1999) com a adaptação proposta por Wachter (2006). Os resultados encontrados no modelo C-CAPM divergiram do esperado, já que a estimativa do coeficiente relativo de aversão ao risco apresentou sinal negativo. Por outro lado, os resultados obtidos no modelo de Wachter (2006) ficaram em linha com o esperado na teoria, tanto em relação à significância dos parâmetros como aos respectivos sinais e magnitudes.

A Common-feature approach for testing present-value restrictions with financial data

It is well known that cointegration between the level of two variables (labeled Yt and yt in this paper) is a necessary condition to assess the empirical validity of a present-value model (PV and PVM, respectively, hereafter) linking them. The work on cointegration has been so prevalent that it is often overlooked that another necessary condition for the PVM to hold is that the forecast error entailed by the model is orthogonal to the past. The basis of this result is the use of rational expectations in forecasting future values of variables in the PVM. If this condition fails, the present-value equation will not be valid, since it will contain an additional term capturing the (non-zero) conditional expected value of future error terms. Our article has a few novel contributions, but two stand out. First, in testing for PVMs, we advise to split the restrictions implied by PV relationships into orthogonality conditions (or reduced rank restrictions) before additional tests on the value of parameters. We show that PV relationships entail a weak-form common feature relationship as in Hecq, Palm, and Urbain (2006) and in Athanasopoulos, Guillén, Issler and Vahid (2011) and also a polynomial serial-correlation common feature relationship as in Cubadda and Hecq (2001), which represent restrictions on dynamic models which allow several tests for the existence of PV relationships to be used. Because these relationships occur mostly with nancial data, we propose tests based on generalized method of moment (GMM) estimates, where it is straightforward to propose robust tests in the presence of heteroskedasticity. We also propose a robust Wald test developed to investigate the presence of reduced rank models. Their performance is evaluated in a Monte-Carlo exercise. Second, in the context of asset pricing, we propose applying a permanent-transitory (PT) decomposition based on Beveridge and Nelson (1981), which focus on extracting the long-run component of asset prices, a key concept in modern nancial theory as discussed in Alvarez and Jermann (2005), Hansen and Scheinkman (2009), and Nieuwerburgh, Lustig, Verdelhan (2010). Here again we can exploit the results developed in the common cycle literature to easily extract permament and transitory components under both long and also short-run restrictions. The techniques discussed herein are applied to long span annual data on long- and short-term interest rates and on price and dividend for the U.S. economy. In both applications we do not reject the existence of a common cyclical feature vector linking these two series. Extracting the long-run component shows the usefulness of our approach and highlights the presence of asset-pricing bubbles.

Constructing common-factor portfolios

In this paper we construct common-factor portfolios using a novel linear transformation of standard factor models extracted from large data sets of asset returns. The simple transformation proposed here keeps the basic properties of the usual factor transformations, although some new interesting properties are further attached to them. Some theoretical advantages are shown to be present. Also, their practical importance is confirmed in two applications: the performance of common-factor portfolios are shown to be superior to that of asset returns and factors commonly employed in the finance literature.

Preços de commodities agrícolas e o comportamento de mercado invertido (backwardation): o caso da soja

A relação entre preços do mercado spot e do mercado futuro e a evidência de Mercado Invertido (backwardation) na estrutura a termo de commodities têm tido ênfase na literatura de economia e de finanças. O objetivo deste trabalho é apresentar as principais causas responsáveis pelo comportamento de Mercado Invertido e identificar as propriedades que caracterizam o equilíbrio de preços em commodities agrícolas. Seja pela existência de prêmio de risco ou do benefício de conveniência, o entendimento dos efeitos sobre a replicação do preço futuro e sobre a estrutura a termo de preços ainda permanece em aberto. A premissa de perfeita replicação de portfólios e a ausência de fricções de mercado implicam, por outro lado, que o entendimento do comportamento de Mercado Invertido advém da compreensão do processo estocástico do próprio ativo subjacente. O apreçamento neutro ao risco, amparado pelos sinais de reversão de preços, permite a modelagem de preços conforme o proposto em Schwartz e Smith (2000), cuja calibração e os resultados serão apresentados para a soja.

Pricing and hedging of oil futures : a unifying approach

We develop and empirically test a continuous time equilibrium model for the pricing of oil futures. The model provides a link between no-arbitrage models and expectation oriented models. It highlights the role of inventories for the identification of different pricing regimes. In an empirical study the hedging performance of our model is compared with five other one- and two-factor pricing models. The hedging problem considered is related to Metallgesellschaft´s strategy to hedge long-term forward commitments with short-term futures. The results show that the downside risk distribution of our inventory based model stochastically dominates those of the other models.

Do equity and foreign currency risk premiums display common patterns?

In da Costa et al. (2006) we have shown how a same pricing kernel can account for the excess returns of the S&:P500 over the US short term bond and of the uncovered over the covered trading of foreign government bonds. In this paper we estimate and test the overidentifying restrictiom; of Euler equations associated with "ix different versions of the Consumption Capital Asset Pricing I\Iodel. Our main finding is that the same (however often unreasonable) values for the parameters are estimated for ali models in both nmrkets. In most cases, the rejections or otherwise of overidentifying restrictions occurs for the two markets, suggesting that success and failure stories for the equity premium repeat themselves in foreign exchange markets. Our results corroborate the findings in da Costa et al. (2006) that indicate a strong similarity between the behavior of excess returns in the two markets when modeled as risk premiums, providing empirical grounds to believe that the proposed preference-based solutions to puzzles in domestic financiaI markets can certainly shed light on the Forward Premium Puzzle.

Tail risk in the hedge fund industry

The dissertation goal is to quantify the tail risk premium embedded into hedge funds' returns. Tail risk is the probability of extreme large losses. Although it is a rare event, asset pricing theory suggests that investors demand compensation for holding assets sensitive to extreme market downturns. By de nition, such events have a small likelihood to be represented in the sample, what poses a challenge to estimate the e ects of tail risk by means of traditional approaches such as VaR. The results show that it is not su cient to account for the tail risk stemming from equities markets. Active portfolio management employed by hedge funds demand a speci c measure to estimate and control tail risk. Our proposed factor lls that void inasmuch it presents explanatory power both over the time series as well as the cross-section of funds' returns.
