Optimum consumption and portfolio rules with money as an asset

This article generalizes Merton's optimum consumption and portfolio rules in continuous time by introducing money as a capital asset and allowing for uncertain inflation. Assuming that prices are log-normally distributed, a three-funds theorem is derived and the introduction of money is shown not to change the form of the standard inflation-adjusted CAPM but to change the market price of risk. The individual's consumption-portfolio problem is completely solved under uncertain inflation if his utility function is iso-elastic in its arguments. Comparative statics are used to assess the influence of changes in exogenous parameters on the individual's optimal rules.     

Bank earning asset behavior and causality between reserves and money: Lagged versus contemporaneous reserve accounting

This paper empirically examines the impact of lagged reserve accounting on large individual bank behavior. Its specific objective is to assess the claim that the institution of LRA has led to a decoupling of the earning asset and reserve adjustment decisions of banks. To accomplish this objective, a system of equations which jointly describe the reserve adjustment and earning asset decisions of banks is estimated and tested for differences in the model between the periods before and after 1968. It is found that bank behavior does not differ fundamentally under LRA. Evidence that banks make their earning asset adjustments promptly and that expected future interest rates are important in their decisions is also presented.     

Global uncertainties and portfolio flow dynamics of the BRICS countries

This paper investigates the dynamics of bond and stock market capital flows to BRICS countries under uncertainties such as global economic policy uncertainty and the US trade policy uncertainty. We use a time-varying Granger causality framework over the January 2008-November 2019 period to analyze the predictive power of uncertainties on capital flows in the form of bond and equity. The results show that the effects are heterogeneous across countries and stronger during the Global Financial Crisis period and post-2018 period while it lost its significance in the subsequent period. The negative influence of uncertainties on capital flows directed to BRICS countries is also evident in the results of non-parametric time-varying panel models. Overall, it is thought that the heterogeneous structure of the causality between uncertainty and portfolio flows into BRICS may present portfolio diversification benefits for global investors.     

Foreign institutional ownership and the speed of leverage adjustment: International evidence

Employing a large sample of 7246 firms across 38 economies from 2000 to 2013, we show a positive relation between foreign institutional ownership (FIO) and firms' speed of leverage adjustment. This positive relation is concentrated for over-leveraged firms that need to decrease financial leverage to rebalance their capital structures. We validate our findings using a 2SLS regression and a DiD estimation to exploit the exogenous variations in FIO generated by the inclusion of MSCI membership and the passage of the JGTRRA. These results suggest that foreign institutional investors play an important monitoring role in mitigating agency conflicts between shareholders and managers. Overall, this paper lends support to the dynamic trade-off theory.     

Common stock returns,real activity,money, and inflation: Some international evidence

This paper tests whether the negative relationship between real stock returns and inflation in the United States is in fact proxying for a positive relationship between stock returns and real activity variables in six major industrial countries over 1966–1979. Consistent with Fama's ‘proxy-effect’ hypothesis, we document a negative relationship between inflation and real activity and a positive one between real stock returns and real activity variables. Real activity variables dominate money growth rates and expected and unexpected inflation in explaining real stock returns. A puzzling result that still remains is the positive role of money and the negative role of expected inflation in explaining these real stock returns in all major industrial countries.     

The shortage of safe assets in the US investment portfolio: Some international evidence

This paper develops a Bayesian Global VAR (GVAR) model to track the international transmission dynamics of two stylized shocks, namely a supply and demand shock to US-based safe assets. Our main findings can be summarized as follows. First, we find that (positive) supply-sided shocks lead to pronounced increases in economic activity which spills over to foreign countries. The impact of supply-sided shocks can also be seen for other quantities of interest, most notably equity prices and exchange rates in Europe. Second, a demand-sided shock leads to an appreciation of the US dollar and generally lower yields on US securities, forcing investors to shift their portfolios towards foreign fixed income securities. This yields sizable positive effects on US output, equity prices and a general decrease in financial market volatility.     

Productivity-based asset pricing: Theory and evidence

In a general real business cycle model, we derive a pricing kernel that involves only production function arguments. The productivity shock is the single factor and the capital stock relative to a productivity measure is the conditioning variable. The model compares favorably with the complementary consumption-based and market-based approaches and with the Fama-French three-factor model. A size premium arises from differences in unconditional sensitivities—small firms are more sensitive to productivity shocks—and a value premium from differences in conditional sensitivities to productivity shocks—growth firms are more sensitive to productivity shocks when the productivity risk premium is low.     

Foreign debt supply in an imperfect international capital market: Theory and evidence

We investigate the determinants of foreign borrowing costs in a stochastically growing economy. We find that these increase with the debt-wealth ratio, depending also upon the volatilities of domestic and foreign origin, and the length of debt contract. In addition, the sensitivity of the short-term debt supply to the debt-wealth ratio exceeds that of long-term debt, and the effects of volatility on the borrowing premium, growth of wealth, and its volatility, depend on the relative size of a direct effect and a secondary portfolio-adjustment effect of the initial shock, as well as the length of the debt contract. Panel regressions suggest that the empirical evidence generally support the theoretical predictions.     

Corporate asset purchases and sales: Theory and evidence

Purchases and sales of operating assets by firms generated $162 billion for shareholders over the past 20 years. This contrasts sharply with the evidence on mergers. This paper characterizes the behavior of value-maximizing firms, which could grow organically, purchase existing assets, or sell assets. The approach yields an endogenous selection model that links asset purchases and sales to fundamental properties of the firm. Empirical tests confirm the predictions of the model. In particular, return on assets and size strongly predict when firms purchase or sell assets, and the transaction size covaries with the value of capital employed by the firm. These findings indicate that corporate asset purchases and sales are consistent with efficient investment decisions.     

The impact of keeping up with the Joneses behavior on asset prices and portfolio choice

This paper studies the asset pricing and portfolio choice implications of keeping up with the Joneses preferences. In terms of portfolio choice, we provide sufficient conditions on the utility function under which no portfolio bias can arise across agents in equilibrium. Regarding asset prices, we find that under Joneses behavior asset prices are a function of the economy's aggregate consumption, the agents preference parameters, the wealth endowment distribution and the weighting across agents in the Joneses definition. We present necessary and sufficient conditions such that equilibrium prices are only a function of aggregate wealth. Non-financial, non-diversifiable income is introduced in the model. In the presence of Joneses behavior, an under-diversified equilibrium emerges where investors will bias their portfolios towards the financial assets that better hedge their exposure to the non-financial income risk.     

External balance adjustment: An intra-national and international comparison

Large external imbalances have become a policy concern. This study investigates the determinants of external balances for regions within a single country—Canadian provinces—as well as for a sample of 18 OECD countries. External balance adjustment may differ for provinces since there are few intra-national barriers to the mobility of capital, goods and labour within Canada. Also, because Canada is a monetary union, there is no currency risk associated with lending and borrowing across provinces, and this may promote inter-provincial financial flows. The estimates show that the short run response of the external balance to disturbances, such as a deterioration in the terms of trade, is typically larger for Canadian provinces than for OECD countries. There is also a much greater speed of adjustment of the external balance in the Canadian provinces. This faster adjustment speed, combined with the larger response of the external balance, means that provinces may see a quicker resolution of external imbalances, but larger deficits or surpluses may emerge before adjustment occurs.     

Liquidity and the dynamic pattern of asset price adjustment: A global view

Global liquidity expansion has been very dynamic since 2001. Contrary to conventional wisdom, high money growth rates have not coincided with a concurrent rise in goods prices. At the same time, however, asset prices have increased sharply, significantly outpacing the subdued development in consumer prices. We investigate the interactions between money and goods and asset prices at the global level. Using aggregated data for major OECD countries, our VAR results support the view that different price elasticities on asset and goods markets explain the observed relative price change between asset classes and consumer goods.     

Fiscal policy and external adjustment: New evidence

Relatively little empirical evidence exists about countries' external adjustment to changes in fiscal policy and, in particular, to changes in taxes. This paper addresses this question by measuring the effects of tax and government spending shocks on the current account and the real exchange rate in a sample of four industrialized countries. Our analysis is based on a structural vector autoregression in which the interaction of fiscal variables and macroeconomic aggregates is left unrestricted. Identification is instead achieved by exploiting the conditional heteroscedasticity of the structural disturbances. Three main findings emerge: (i) the data provide little support for the twin-deficit hypothesis, (ii) the estimated effects of unexpected tax cuts are generally inconsistent with the predictions of standard economic models, except for the US, and (iii) the puzzling real depreciation triggered by an expansionary public spending shock is substantially larger in magnitude than predicted by traditional identification approaches.     

Monotonicity in asset returns: New tests with applications to the term structure,the CAPM,and portfolio sorts

Many theories in finance imply monotonic patterns in expected returns and other financial variables. The liquidity preference hypothesis predicts higher expected returns for bonds with longer times to maturity; the Capital Asset Pricing Model (CAPM) implies higher expected returns for stocks with higher betas; and standard asset pricing models imply that the pricing kernel is declining in market returns. The full set of implications of monotonicity is generally not exploited in empirical work, however. This paper proposes new and simple ways to test for monotonicity in financial variables and compares the proposed tests with extant alternatives such as t-tests, Bonferroni bounds, and multivariate inequality tests through empirical applications and simulations.     

中央银行外汇干预:操作方式与效用评价

本文将外汇干预、货币政策转型纳入到NK-DSGE理论模型框架中,引入风险规避的外汇交易者,在传统非抛补利率平价表达中加入资本管制因素,研究不同类型冲击、不同外汇干预情景下宏观经济变量的反应。研究结果表明:中央银行进行外汇干预时,采用不同的干预方式对汇率波动程度的影响有所不同;相较于任意干预,基于规则的干预对汇率的调整过程更为稳健,且比任意干预成本更小;在应对冲击方面,任意干预效果不显著,基于规则的干预则具有较强的稳定作用;外汇干预与货币政策在一般均衡框架下具有很强的互动性。中央银行应构建外汇干预策略框架,建立外汇干预目标体系,设定人民币汇率干预区间,并在此基础上选择合理的干预方式,量化干预效果,做好外汇干预的事后评估,以保障宏观经济的稳健运行。     

Financial constraints and asset pricing: comprehensive evidence from London Stock Exchange

This study provides comprehensive evidence on the pricing of financial constraints (FC) risk on London Stock Exchange during the period 1988–2013. Utilizing a large number of proxies for FC, we find that investors are not compensated with higher premia for holding shares of financially constrained firms. To the contrary, in most of the cases, the most constrained firms significantly underperform, both statistically and economically, the least constrained ones. Focussing on the Whited–Wu index to construct a zero-cost FC factor that goes long the most constrained firms and sells short the least constrained ones, we find that this factor carries a significantly negative premium and it is priced in the cross-section over and above the commonly used risk factors.     

Religiosity and bank earnings management: Revisiting international evidence

The modernization theory forecasts a sharp declining effect of institutionalized religion on human behavior owing to the extensive economic development. However, this prediction is rejected and proved that religious values and beliefs have a pervasive influence on individual conduct. Based on this salient evidence, we examine the influence of religious social norms on bank earnings management behavior with regard to ongoing economic development. We use 20,715 bank-year observations from 1318 listed banks of eight geographical regions. We, further, employ an updated dataset of 2007–2021 to resemble the economic prosperity time period. Our study discards the prediction of the modernization theory and reveals that banks located in countries with high religiosity are less likely to manage their reported earnings. While comparing conventional banks with Islamic ones, conventional banks are found to be less prone to the earnings management practice than that of their Islamic counterparts. We also find religiosity to have a greater magnitude of effect on the accounting manipulation in the crisis period than in the post-crisis one. The cross-regional differences in religious values bring differential effects on this unethical practice. Our results are robust with the alternative measures of earnings management and alternative model specifications.     

Earnings quality and firm valuation: international evidence*

This study uses a sample of over 7000 firms in 38 countries to investigate the relation between firm valuation and earnings quality. We find a positive and significant relation between firm valuation and an aggregate earnings quality measure based on seven earnings attributes (accruals quality, persistence, predictability, smoothness, value relevance, timeliness, and conservatism). This relation is particularly strong for firms with greater investment opportunities and more need for external finance, and for firms in low investor protection countries. Thus, firms are able to compensate for a weak legal environment by adopting higher earnings quality standards, particularly when they need to gain access to global capital markets. Overall, our findings suggest that firms with higher earnings quality are valued more highly in stock markets, supporting the idea that investors require a premium for the information risk associated with lower‐quality earnings.     

Investment dynamics with fixed capital adjustment cost and capital market imperfections

This paper examines the implications of financing frictions on capital stocks and on capital accumulation in the presence of non-convex costs of adjusting the capital stock. In this setup finance has an influence on both, the level of capital and the timing of investment. Finance and productivity are complements and finance influences investment the strongest when firms wish to significantly adjust capital for fundamental reasons. These theoretical considerations are confronted with UK data. While finance is mostly irrelevant for long-term capital decision, the short-run investment function shows a significant impact of finance, which is also strongest for strong fundamental investment incentives.     

Selecting a portfolio with skewness: Recent evidence from US,European, and Latin American equity markets

Polynomial goal programming, in which investor preferences for skewness can be incorporated, is utilized to determine the optimal portfolio from Latin American, US and European capital markets. The empirical findings suggest that the incorporation of skewness into an investor’s portfolio decision causes a major change in the resultant optimal portfolio. The empirical evidence indicates that investors do trade expected return of the portfolio for skewness.
