Information,interest rates,and the volatility of asset prices

The volatility of an asset price is modelled as a function of the volatility of an information signal, real interest rates and inflation expectations. Volatility depends on the duration of cash flows, and the degree to which cash flows are indexed to real rates and inflation. The model is applied to determine asset betas, the volatility of the futures prices of assets and the volatility of equity prices.     

UNANTICIPATED INFLATION, TAXATION, AND COMMON STOCKS

This paper focuses on the effects of unanticipated inflation on the market value of equity in a system with corporation tax and historic cost depreciation. It is shown that there exists a unique combination of debt and equity under which inflation neutrality is obtained, Whether or not unanticipated inflation hurts or benefits the stockholders in a particular firm depends upon a number of conditions. These include the depreciation rate of its assets relative to the amortization rate of its debt. Finally, the present tax system is contrasted with a fully indexed system involving replacement cost depreciation and indexation

Fiscal Requirements for Dynamic and Real Determinacies in Economies with Private Provision of Liquidity: A Monetarist Assessment

We study the impact of fiscal policies on the inherent links between inflation, unemployment, and asset prices in an environment where firms provide liquidity and the central bank follows a constant money growth rate rule. Firms, other than hiring workers, also supply private assets that are not only useful as a store of value but also as collateral. When firms are not taxed and public debt is scarce, the economy is non-Ricardian so that real indeterminacies can be observed. Moreover, labor market characteristics do not affect the demand for government liabilities. However, when agents face public and private asset scarcity, labor market conditions then impact asset prices and inflation. We further show that irrespective of the type of asset scarcity agents face, when firms are taxed non-ad valorem, not only the level of tax revenues but also its composition matter for real allocations. Moreover, we show that labor market conditions directly affect the dynamics of all government liabilities and inflation.     

The Effects of Inflation and Taxes on Growth Investments and Replacement Policies

This paper investigates the effect of inflation and taxes on the optimal duration of investments. The main conclusion is that inflation does not always increase the duration of investments. For example, in the case of equipment with a short replacement cycle, increased inflation tends to decrease the duration of the cycle. Contrary to the common theoretical analysis, these results imply that inflation may increase some forms of capital investments.     

Expected Inflation and Interest Rates in a Multi-asset Model: A Note

This paper analyzes the effect of expected inflation on nominal interest rates, in a theoretical model with money and two different bond types. The inclusion of three assets instead of the usual two causes the effect of expected inflation on the interest rates to deviate from unity. Depending on the sizes of the wealth and interest rate effects on the various asset demands, the effect of expected inflation could even be negative. Several special cases are also considered, and the implications for the interpretation of empirical results are discussed.     

Financial sophistication and the distribution of the welfare cost of inflation

The welfare cost of anticipated inflation is quantified in a calibrated model of the U.S. economy that exhibits tractable equilibrium dispersion in wealth and earnings. Inflation does not generate large losses in societal welfare, yet its impact varies noticeably across segments of society depending also on the financial sophistication of the economy. If money is the only asset, then inflation mostly hurts the wealthier and more productive agents, while those poorer and less productive may even benefit from inflation. The converse holds in a more sophisticated financial environment where agents can insure against consumption risk with assets other than money.     

Inflation and the evolution of firm-level liquid assets

This paper shows that inflation has been an important determinant of firm-level liquid asset holdings. Liquid assets as a share of total assets – the cash ratio – for U.S. corporations steadily declined from the 1960s to the early 1980s, and has since steadily increased. Our empirical analysis finds that inflation is a key factor accounting for these changes. We show that these liquid asset holdings are imperfectly hedged against inflation. Hence, changes in inflation alter the real value of a firm’s liquid asset portfolio causing them to readjust these balances.     

An analysis of nondeductible IRA contributions and Roth IRA conversions

On average investors have an income replacement rate of 64% of their pre-retirement income, which in many cases results in a lower tax rate in retirement. We analyze the impact of declining withdrawal tax rates on the choice between taxable mutual fund investments and nondeductible IRAs. The relative attractiveness of the taxable mutual fund option declines significantly when withdrawal tax rates decline. Converting existing IRAs to Roth IRAs is generally beneficial for investors who remain in the same tax bracket upon withdrawal. For short (long) time horizons and low (high) expected returns, the marginal value of conversion in 1998 is greater (less) than the marginal value of optimal conversion. For investors dropping into the 15% tax bracket, conversion is generally not beneficial unless the conversion is done optimally, the time horizon is long, and the expected return is high. Investors in the 15% tax bracket should convert existing IRA assets.     

企业处置固定资产的税务处理研究

企业处置固定资产经常会涉及到税务处理,由于固定资产处置方式多样,涉及到增值税和营业税两个税种,且在增值税转型后,纳税人销售旧货（包括固定资产）的征收方式出现了复杂化。不利于纳税人的掌握和理解,因此本文基于税务会计处理的角度,对固定资产进行重新分类,针对不同固定资产的类别,分情况详细阐述了不同固定资产的处置方式下的涉税处理。     

Tax-Induced Intertemporal Restrictions on Security Returns

This article derives testable restrictions on equilibrium asset prices when investors have the option to time the realization of their capital gains and losses for tax purposes. The tax-timing option alters both the magnitude and timing of equity returns relative to those in a tax-free model. The tax-induced restrictions are empirically examined, and the tax rates and preference parameters are estimated. While the tax-free model can be rejected in favor of the tax-based model as the specified alternative, the tax-based model is still unable to adequately explain cross-sectional differences in asset returns.     

股价波动、通货膨胀与固定资产投资——基于协整和VEC模型的经验证据

经验证据表明,我国股票市场时全社会固定资产投资的影响作用还比较小,股票市场对固定资产投资的冲击在部分时段是负效应,可能存在部分"挤出效应".而影响固定资产投资的主要因素是GDP的变动.另外在我国,通货膨胀率对固定资产投资的影响比较明显.从短期来看,固定资产投资也带动了通货膨胀.国内固定资产投资的波动不仅受偏离均衡的影响,还受到GDP、Cpi、上证综合指数与存款利率水平自身变动的影响.央行应加强审慎的宏观调控,优化信贷结构,加强农村水利建设的长期投资,为经济结构调整和经济增长方式的转变提供稳定的货币金融环境.     

Taxation and the Taylor principle

A nominal tax system is added to a sticky-price monetary business cycle model. When nominal interest income is taxed, the coefficient on inflation in a Taylor-type monetary policy rule must be significantly larger than one in order for the model economy to have a determinate rational-expectations equilibrium. When effective tax rates are raised by inflation, the stability of the economy's equilibrium can be adversely affected. Finally, when depreciation is treated as a charge against taxable income, an even larger weight on inflation is required in the Taylor rule in order to obtain a determinate and stable equilibrium.     

Taxation of Financial Assets in Developing Countries

In developing countries most of the financial assets are depositsat commercial banks. This article focuses on the implicit taxationof financial assets through seigniorage, reserve requirements,lending targets, and interest ceilings combined with inflation.The impact of taxation on financial deepening increases significantlywith the tax rate, as shown by cross-sectional and time seriesdata for selected countries in Sub-Saharan Africa and SoutheastAsia. The problem of measuring revenue is examined, and theefficiency cost of taxation is analyzed in a Harberger framework.Although taxes on financial assets have a low administrativecost, the excess burden caused by the misallocation of resourcesis probably a much higher fraction of revenues than that ofother taxes.     

Taxes and the Fisher Effect: A Clarifying Analysis

Supply and demand functions for loanable funds are postulated for a no-inflation economy and equilibrium levels of saving, investment, and the interest rate are specified. Certainty and nondepreciating assets are assumed. An exogenous inflation rate is imposed upon this same economy and new equilibrium values for these same variables are established. The analysis is performed twice. The first time, a Modigliani-Miller [17] tax structure is assumed while the second analysis assumes a Miller-Scholes [15] tax structure. In both cases, inflation causes the nominal rate to increase by more than the inflation rate. The analysis is repeated assuming that investments live for one period and are then written off against taxable income at historical cost. In both tax structures, the level of saving and investment is a decreasing function of the inflation rate.     

Generalized separation of the portfolio decision process under uncertain inflation and asset pricing implications

By way of investigating the portfolio separability and hedging services of assets under uncertain inflation, this paper transforms the Friend-Landskroner-Losq (1976) model into an empirically tractable asset pricing relationship which is linear in the market factor and the inflation factor. This relationship is consistent with a gradual accumulation of empirical evidence which uniformly supports the existence of an additional factor(s) besides the market. The economic source of the additional factor is established in terms of relative hedging services of assets. The testable implications of the model are discussed by way of deriving its ex post analog. Further, due to generalized separability and the attendant mutual funds, the portfolio decision process can be decentralized under an inflationary environment.     

Taxes and the acquisition of depreciable assets: The Tax Reform Act of 1986 and the alternative minimum tax

Analysis of firm investment behavior during 1982–1993 shows that the Tax Reform Act of 1986 (TRA 86) Public Law No. 99-514 substantially affects both purchases and leases of depreciable assets. The changes in the regular corporate income tax rules are shown to lower asset acquisition. The effect of the alternative minimum tax (AMT) is found to vary with the debt share in firms’ capital structure and with the frequency of AMT exposure during the life of the assets acquired. On average, TRA86 depresses asset purchases less for firms that are subject to the AMT: AMT somewhat mitigates the negative effects of the regular tax rules.     

我国资产价格波动与通货膨胀关系的理论研究与实证分析

随着次贷危机引发全球性金融危机,学术界对于货币政策是否以及如何对资产价格做出反应的争议再起。本文根据协整分析技术、Granger因果检验方法和误差修正模型,利用1998—2008年中国的季度数据,对资产价格与通货膨胀之间的关系进行了实证研究。实证研究表明：第一,我国资产价格与通货膨胀之间确实存在长期的均衡关系,其中房价变动对通货膨胀的影响大于股价变动对通货膨胀的影响;第二,我国资产价格与通货膨胀之间存在着单向的因果关系,即股票价格与房价上涨是通货膨胀的原因。     

Monetary Policy and Asset Prices: A Mechanism Design Approach

We investigate the effects of monetary policy on asset prices in economies where assets are traded periodically in bilateral meetings. The trading mechanism is designed to maximize social welfare taking as given the frictions in the environment and monetary policy. We show that asset price “bubbles” emerge in a constrained‐efficient monetary equilibrium only if liquidity is abundant and the first‐best allocation is implementable. In contrast, if liquidity is scarce, assets are priced at their fundamental value in any constrained‐efficient monetary equilibrium, in which case an increase in inflation has no effect on asset prices, but it reduces output and welfare.     

Capital Structure and Assets: Effects of an Implicit Collateral

This paper analyses a firm's capital structure choice when assets have outside value. Valuable assets implicitly provide a collateral and increase tax shield exploitation. The key feature in this paper is asset value uncertainty, implying that it is unknown ex ante whether the equity holders ex post optimally sell the assets or re‐optimise the capital structure. Ex ante, more uncertain asset value decreases leverage, but not firm value, and selling the assets becomes less likely. Firms should tend to invest in assets whose value is less correlated to changes in earnings and, in addition, asset sales are less likely when this correlation is low.
