The Implications of First-Order Risk Aversion for Asset Market Risk Premiums

Existing general equilibrium models based on traditional expected utility preferences have been unable to explain the excess return predictability observed in equity markets, bond markets, and foreign exchange markets. In this paper, we abandon the expected-utility hypothesis in favor of preferences that exhibit first-order risk aversion. We incorporate these preferences into a general equilibrium two-country monetary model, solve the model numerically, and compare the quantitative implications of the model to estimates obtained from U.S. and Japanese data for equity, bond and foreign exchange markets. Although increasing the degree of first-order risk aversion substantially increases excess return predictability, the model remains incapable of generating excess return predictability sufficiently large to match the data. We conclude that the observed patterns of excess return predictability are unlikely to be explained purely by time-varying risk premiums generated by highly risk averse agents in a complete markets economy.

A Review and Bibliography of Early Warning Models

This note is intended to share some observations regarding a non-exhaustive collection of the early warning literature from 1971 to 2011. Evolution of the interest in early warning models, methodological spectrum of studies and coverage of economic variables are briefly discussed in addition to providing a bibliography.Early warning systems, bibliometric analysis

Size and liquidity effects in Nigeria: an industrial sector study

This study estimates liquidity premiums using the recently developed Liu (2006) measure within a multifactor capital asset pricing model (CAPM) including size premiums and a time varying parameter model for the West African emerging market of Nigeria. The evidence suggests that liquidity factors are relevant only for financial and basic materials sector stocks while size factor is more generally relevant in explaining the cross section of stock returns in the Nigerian domestic equity market. Costs of equity estimates are high further underlining the limitations of this market as a capital-raising venue in contrast to the dominant banking sector

Hedging the exchange rate risk in international portfolio diversification : currency forwards versus currency options

As past research suggest, currency exposure risk is a main source of overall risk of international diversified portfolios. Thus, controlling the currency risk is an important instrument for controlling and improving investment performance of international investments. This study examines the effectiveness of controlling the currency risk for international diversified mixed asset portfolios via different hedge tools. Several hedging strategies, using currency forwards and currency options, were evaluated and compared with each other. Therefore, the stock and bond markets of the, United Kingdom, Germany, Japan, Switzerland, and the U.S, in the time period of January 1985 till December 2002, are considered. This is done form the point of view of a German investor. Due to highly skewed return distributions of options, the application of the traditional mean-variance framework for portfolio optimization is doubtful when options are considered. To account for this problem, a mean-LPM model is employed. Currency trends are also taken into account to check for the general dependence of time trends of currency movements and the relative potential gains of risk controlling strategies

An Index of Financial Stress for Canada

The authors develop an index of financial stress for the Canadian financial system. Stress is defined as the force exerted on economic agents by uncertainty and changing expectations of loss in financial markets and institutions. It is a continuous variable with a spectrum of values, where extreme values are called financial crises. Information about financial stress is extracted from a wide array of financial variables using several techniques, including factor analysis, econometric benchmarking, and generalized autoregressive conditional heteroscedasticity (GARCH) modelling. An internal Bank of Canada survey is used to condition the choice of variables and to evaluate their ability to reflect the responses to the survey regarding highly stressful financial events. The authors show that alternative measures of financial crises suggested by the literature do not accurately reflect the results of the survey, while several measures developed in this paper do reflect them.Financial institutions; Financial markets

Equity and bond flows to Asia and Latin America : the role of global and country factors

The authors investigate what has motivated the large portfolio flows to several developing countries in recent years. Using monthly data on U.S. capital flows to nine Latin American and nine Asian countries (instead of monthly reserves data), they analyze the behavior of bond and equity flows to those countries. Using panel data, they find that global factors - such as a drop in U.S. interest rates and the slowdown in U.S. industrial production - are important in explaining capital inflows. But country developments are at least as important in determining those flows, especially for Asia. They also find that equity flows are more sensitive than bond flows to global factors, but that bond flows are generally more sensitive to a country's credit rating and to the secondary market price of debt.Economic Theory&Research,Banks&Banking Reform,Financial Intermediation,Environmental Economics&Policies,Macroeconomic Management

The Internationalization of Equity Markets

This introduction to a forthcoming NBER volume on 'The Internationalization of Equity Markets' argues that the existing finance literature has in some respects not kept pace with world trends. Most empirical studies fail to take due account of the diversity of assets offered by countries around the world, the diversity of locales in which investors live, and the diversity of institutional peculiarities that characterize the markets in which assets and investors are brought together. Four of the papers in the volume are econometric studies of asset pricing and home-country bias in internationally integrated equity markets. The other four examine such issues as emerging markets, country funds, trading volume, location, taxes, controls, and other imperfections in international markets.

Proliferation of risk and policy responses in the EU financial markets

Summary for non-specialistsThis study draws attention to the proliferation of tail risks in financial markets prior to and during the course of the recent global financial crisis. It examines the level of tail risks in selected equity, interbank lending and foreign exchange markets in selected EU Member States in relation to the United States. The extent of tail risks is assessed by applying general error distribution (GED) parameterization in GARCH volatility tests of the examined variables. The empirical tests prove that tail risks were pronounced across all of the examined European financial markets throughout the crisis. They were also significant prior to the crisis outbreak. The analyzed interbank lending markets exhibited more extreme volatility outbursts than the equity and foreign exchange markets. Several countercyclical monetary and macroprudential policies aimed at abating tail risks are identified and discussed. Flexible capital adequacy and contingent capital requirements for financial institutions are advocated.Global financial crisis equity markets foreign exchange markets monetary policies macroprudential policies Orlowski

Consolidation and efficiency in the financial sector: a review of the international evidence

In response to fundamental changes in regulation and technology, the financial industry around the world is undergoing an unprecedented wave of consolidation. A growing body of empirical literature has attempted to measure the efficiency gains from M&As; however there is little sense of how the results might depend on the country, industry and time period analysed. In this paper we review critically works that cover the main sectors of the financial industry (commercial and investment banks, insurance and asset management companies) in the major industrialized countries over the last twenty years, searching for common patterns that transcend national and sectoral peculiarities. We find that consolidation in the financial sector is beneficial up to a relatively small size in order to reap economies of scale, but there is little evidence that mergers yield economies of scope or gains in managerial efficiency.mergers, efficiency, bank mergers
