On the validation of cost push: A comment

A recent article in this journal examined the effects of ‘cost-push’ disturbances in a model in which government expenditure was fixed in nominal rather than real terms. It was suggested that, under certain circumstances, these nominal government expenditure targets could destabilise the model. In this note we show that, on the contrary, this particular model is always stable, whether or not government expenditure is fixed in nominal or real terms.     

Intangible capital,corporate valuation and asset pricing

Recent studies have found unmeasured intangible capital to be large and important. In this paper we observe that by nature intangible capital is also very different from physical capital. We find it plausible to argue that the accumulation process for intangible capital differs significantly from the process by which physical capital accumulates. We study the implications of this hypothesis for rational firm valuation and asset pricing using a two-sector general equilibrium model. Our main finding is that the properties of firm valuation and stock prices are very dependent on the assumed accumulation process for intangible capital. If one entertains the possibility that intangible investments translates into capital stochastically, we find that plausible levels of macroeconomic volatility are compatible with highly variable corporate valuations, P/E ratios and stock returns.

Franchising,agency problems,and the cost of capital

Explanations for franchising are examined in the context of the US hotel industry. The study is distinct from previous research on franchising because it explicitly recognizes the existence of three organizational forms, whereas previous research has focused exclusively on two of these three forms. The two organizational forms examined in previous work are franchising and company ownership. The additional organizational form is company-management/investor-ownership, which involves management by the franchisor and ownership by outside investor groups. A plausible explanation for the existence of the last organizational form is based on the availability of low cost capital from non-chain sources.     

Financial development,financial liberalization and social capital

The relationship between financial liberalization policies and financial development is controversial. The impact of these policies differs greatly across countries. In the literature, the quality of formal institutions has been identified as an important source of this heterogeneity, as countries with a weak institutional environment generally fail to benefit from financial liberalization. Using panel data covering 82 countries for the period 1973–2008, we find evidence that social capital may substitute for formal institutions as a prerequisite for effective financial liberalization policies. In particular, we find that during the post Washington-consensus period countries with a high prevailing level of social capital can ensure that financial liberalization positively influences financial development, despite the poor quality of their formal institutions.     

Debt policy, corporate taxes, and discount rates

This paper applies the standard risk-neutral valuation framework to tax shields generated by dynamic debt policies. We derive a partial differential equation (PDE) for the value of the debt tax shield. For a class of dynamic debt policies that depend on the asset's free cash flows, value, and past performance, we obtain closed-form solutions for the PDE. We also derive the tax-adjusted cost of capital for free cash flows and analyze the conditions under which the weighted average cost of capital is an appropriate discount rate. Finally, we derive closed-form solutions for equity betas, which differ from the formulas that have traditionally been used to lever and unlever equity betas.     

Monetary policy,corporate profit and house prices

By using portfolio theory, we explain the highly observed correlation between the seemingly unrelated corporate profit and house prices in the United States. We test the predictions of the underlying model using a vector autoregression representation and find the data to be supportive of the theory. Monetary impulses explain high correlation as both corporate profit and house prices exhibit similar dynamics in response to a monetary impulse. Robustness checks are presented by using the federal funds rate instead of the monetary base as a measure of the stance of monetary policy and by using other model variations. In all cases, the results are robust.     

Tax policy, venture capital, and entrepreneurship

The paper studies the effects of tax policy on venture capital activity. Entrepreneurs pursue a single high risk project each but have no own resources. Financiers provide funds, covering investment cost plus an upfront payment, in exchange for a share in the firm. The contract must include incentives to enlist full effort of entrepreneurs. Venture capitalists also assist with valuable business advice to enhance survival chances. The paper develops a general equilibrium framework with a traditional and an entrepreneurial sector and investigates the effects of taxes on the equilibrium level of managerial advice, entrepreneurship and welfare. It considers differential wage and capital income taxes, a comprehensive income tax, progressive taxation as well as investment and output subsidies to the entrepreneurial sector.

Progressive taxation,tax exemption,and corporate liquidation policy

This paper develops a real options model of a firm that operates in continuous time with an infinite horizon. The firm receives stochastic profit flows that are subject to progressive taxation. Tax progression arises from an exogenously given tax exemption threshold that makes the average tax rate increase with the tax base. The firm possesses an option to liquidate its operation, which is optimally exercised when the firm's profit flow reaches an endogenously determined threshold level (the liquidation trigger) from above. We show that the firm's liquidation trigger under progressive taxation increases with either a reduction in the tax exemption threshold or an increase in the corporate income tax rate. Corporate income taxes are thus not neutral when tax schedules are progressive.     

一个GDP动力学模型与货币金融政策

This article applies a dynamics approach in the research of monetary law of movement under the complex system of social economical operation, and characterizes the movement of money in a social institutional framework during GDP’s formation. Assuming that humans’ pursuit of the return of their money expenditure is a sensible course of nature, it defines the expression of money circulation velocity, and proceeds to deduce the basic differential equation of money circulation. By solving this equation, we can get the expression for a GDP dynamics model. After empirically testing the expression, this article draws a conclusion: GDP and the money in circulation (M₀) share the positive correlation when the monetary financial institution remains unchanged.      

Determinants of corporate capital structure: evidence from Hungarian firms

This paper investigates the capital structure of Hungarian firms using a cross-section and a panel data approach. The data set is composed of balance sheet data and information on market structure for 1100 firms from 1992 to 1996. Evidence is found of imperfections that constrain firms in the achievement of their optimal capital structure, but also some positive indications: there are no distortions typical of the planned system and no signs of the presence of soft budget constraints.     

Idiosyncratic risk and financial policy

In economies subject to uninsurable idiosyncratic risks, competitive equilibrium allocations are constrained inefficient: reallocations of assets support Pareto superior allocations. This is the case even if the asset market for the allocation of aggregate risks is complete.

Monetary policy and corporate bond yield spreads

Firm characteristics, economic conditions and policy regimes are the key determinants that most researchers have used to explain corporate bond yield spreads. In this article, we examine whether monetary policy shocks are also important determinants given their ability to affect default risk, risk aversion and liquidity premiums. Using a Vector Autoregression (VAR) with long-run monetary neutrality, we find that monetary policy shocks do, in fact, account for a large portion of the variation in corporate bond yield spreads.     

Idiosyncratic risk and the cost of capital: the case of electricity networks

We analyze the treatment and impact of idiosyncratic or firm-specific risk in regulation. Regulatory authorities regularly ignore firm-specific characteristics, such as size or asset ages, implying different risk exposure in incentive regulation. In contrast, it is common to apply only a single benchmark, the weighted average cost of capital, uniformly to all firms. This will lead to implicit discrimination. We combine models of firm-specific risk, liquidity management and regulatory rate setting to investigate impacts on capital costs. We focus on the example of the impact of component failures for electricity network operators. In a simulation model for Germany, we find that capital costs increase by \(\sim \) 0.2 to 3.0 % points depending on the size of the firm (in the range of 3–40 % of total cost of capital). Regulation of monopolistic bottlenecks should take these risks into account to avoid implicit discrimination.
