Effects of an anticipated expansion in international public goods on public capital accumulation

This paper presents a generic model to include public capital accumulation and the services of international public goods provided by a neighbor country. It examines the long-run and short-run responses of private and public capital accumulation in the home country to an anticipated increase in international public goods. It is found that the home economy in effect cuts its public capital stock, but keeps an unchanged private capital stock in the long run when a neighbor commits itself to expanding the stock of public goods in the future. The key factor determining the short-run responses of the home country is the extent to which it will match its government spending with a neighbor country's policy, which is associated with the relative difference between the marginal utility of consumption and that of home public capital affected by an increase in international public goods.     

Environmental regulation and optimal investment behavior: A micro-economic analysis

This paper develops a simple optimal control model of the firm's investment decisions in the presence of environmental restrictions. The firm is assumed to jointly decide the optimal levels of gross investment, scrappage of capital, and maintenance expenditures. The results of the model indicate that all investment decisions, including both abatement equipment and productive capital, are affected by the manner in which environmental regulations are designed. Moreover, these impacts can be further altered if other unrelated regulations, such as rate base regulation, are concurrently imposed on the firm.     

Interdependent capital structure choices and the macroeconomy

This study shows that capital structure choices of US corporations are interdependent across time. We follow a two-step estimation approach. First, using a large cross-section of firms we estimate year-by-year average capital structure choices, i.e., the average firm’s percentage of new funding that is secured through debt, its term composition, and the percentage of new equity represented by retained earnings. Second, these time series are included in a Factor Augmented Vector Autoregressive model in which three factors representing real economic activity, expected future funding conditions, and prices, are included. We test for the interdependence between optimal capital structure decisions and for the influence exerted by macroeconomic conditions on these decisions. Results show there is a hierarchical order in which firms make capital structure decisions. They first decide on the share of debt out of total new funding they will hire. Conditional on this they decide on the term of their debt and on their earnings retention policy. Of outmost importance, macroeconomic factors are key for making capital structure decisions.     

A Model of Small Firm Capital Acquisition Decisions

This paper presents a model that describes the dynamics of small firm capital acquisition decisions. The model proposes that the primary factors influencing capital acquisition decisions are (1) availability of information, (2) ease of capital acquisition, (3) owner’s goals, and (4) terms of external providers of capital. The paper discusses the relationships between these primary influence variables and capital acquisition decisions. A better understanding of the factors influencing capital acquisition can provide insight into the process by which small firms make capital acquisition decisions. A better understanding of these dynamics can also lead to improved support systems and conditions for small businesses that may be searching for capital. Insight from the model can be useful for business owners, business consultants, and classroom instructors.     

Behavior of the firm in a market for heterogeneous labor

This paper develops a dynamic model of the firm in a labor market where workers and jobs are heterogeneous with respect to skill. The firm's recruitment policy, in a heterogeneous market, consists of both a wage offer and a skill requirement. The explicit derivation of this policy serves to clarify the difference between the long-run and short-run relationship between wages and skills. The short-run shift in this relationship helps to explain the occupational upgrading that occurs in cyclical upswings. The model also highlights the impact of the skill level distribution on the rate of change of firms' wage offers.     

The cost of capital in the international firm

This paper argues that the international firm should use the firm's global weighted average cost of capital to evaluate investment decisions, domestic and international, and to judge the performance of affiliates at home and abroad. The paper discusses the adjustment necessary to quantitate exchange risk and to account for financing that is subsidized or tied to particular investments. Foreign subsidiaries, it is argued, do not have an independent capital structure because their liabilities are explicitly or implicitly the obligation of the parent firm.     

Two-stage optimal control problems and optimality conditions

When an optimal investment decision is studied for a firm whose capital goods are subject to a delivery lag, a control problem with a time-delay argument in the objective function emerges. Such a problem under a set of simple assumptions is shown to be reducible to a two-stage optimal control problem. The significance of this is that familiar tools from standard optimal control theory are applicable to the resulting two-stage problem. Necessary conditions are presented for a general two-stage problem with an adjustable switching time. Some specific results are also obtained for several special cases.     

Production theory,uncertain prices and investment portfolios

This paper examines the allocative decisions of a competitive firm where input and output prices are uncertain and where the capital asset pricing model prevails. The firm behaves much as a profit maximizer under certainty, except that certainty equivalent prices formally replace the known prices. These certainty equivalent prices are composed of the expected price, the covariance of the price with the market (a measure of systematic risk) and a measure of risk aversion in the economy. Both static and comparative static propositions emerge in a natural way as extensions of standard, competitive and profit maximizing behavior. In addition, the model contains both the certainty case and the risk-neutral case as limiting examples.     

Diversity,Social Goods Provision,and Performance in the Firm

Economists have studied the effect of diversity on the provision of social goods and the stock of social capital. In parallel, management scholars have studied the effect of diversity in the workplace on firm performance. We integrate these two growing literatures and explore these questions with a unique dataset. A firm provided eight years of individual‐level employee survey data, which include measures of the stock of social capital, plus office‐level measures of diversity and performance. We find some evidence that more gender‐homogeneous offices enjoy higher levels of social goods provision but those offices do not perform any better and may actually perform worse.     

An adjustment cost model of long-term employment in Japan

A dynamic factor demand model is presented which pays special attention to the prevalence of a long-term employment relationship in Japan. The model is based on the representation of technology by a variable cost function with adjustment costs for employment and capital stock, where the variable cost consists of the sum of overtime costs and materials costs. With employment being quasi-fixed and scheduled hours institutionally regulated, short-run adjustments are mostly made by overtime hours. Application to a time-series data on the Japanese electrical machinery industry indicates quasi-fixity of capital and employment and reproduces short-run overshooting of overtime hours to compensate for the sluggish adjustment of employment.     

The Workweek of Capital and Capital Utilization in Manufacturing

Over the typical intervals of time studied in economic analysis, the flow of capital services is not a fixed proportion of the capital stock. Much of the short-run variation in capital services comes from the duration of operations. This paper presents new estimates of the workweek of capital from the Census Bureau' Survey of Plant Capacity (SPC), both for our own analytical use and to make workweek data more widely available to other researchers. The paper uses these workweek estimates to reconsider various results in the literature on capital utilization and productivity growth.     

The crumbling of apartheid: An application of managerial economics

The thesis of this examination of Apartheid in the Republic of South Africa is that the sophistication of capital structure, whether viewed macro-economically or at the level of the firm, passes nigh-irrestible power to even unorganized workers. This non-Marxist social system model is empirically substantiated by South African economic history but, more particularly, from managerial decisions in respect of the production function – especially in the critical gold-mining industry – over time. This leads to the logical conclusion that the dynamic intensification of foreign capital investment in the Republic alone can end that country's system of Apartheid.     

Introducing the supply side into the LBS Model

This Briefing Paper describes a new version of the London Business School model, which incorporates our most recent research on the supply side. The changes reflect the desire to improve the specification of the supply-side of the model, and to capture the effects of taxes on the incentives to save, invest and to work, while still retaining the basic features of the income-expenditure framework. The main features of the new model are: - Gross domestic product is determined as the sum of the outputs of five sectors. Previously GDP was determined by the demand side as the sum of the expenditure components. - Domestic demand for the output of the private sector depends on domestic absorption and on the price of this output relative to import prices. Overseas demand for exports depends on world economic activity and on the price of exports relative to the world price of exports. - Supply depends on the capital stock, real unit labour costs and real raw material prices. In the short run, input prices are allowed to affect the mix between goods which are exported and those which are supplied to the domestic market. In the long run, however, the mix depends only on the price of exports relative to the price of domestically supplied goods (i.e., relative profitability). - In the short run, disequilibrium in the goods market is reflected in adjustments to prices, inventories and the external balance. - Since gross domestic product is determined by summing the output of each sector, output decisions are reconciled with expenditure decisions by making imports the difference between final expenditure and aggregate supply. - In the long run, increases in government expenditure crowd out private expenditure, but the effect takes several years to come through. - A cut in corporation taxes which is not financed by higher taxes elsewhere boosts the supply side by raising investment and the capital stock, but not by enough to raise revenues sufficiently to pay for the tax cut. Private sector saving increases but not by enough to fund higher public sector borrowing, so the current account goes into deficit. - In the short run, both supply and demand factors influence economic activity; in the long run, the path of the economy depends only on population growth, capital accumulation and technical progress.     

Investment and Uncertainty: A Theory‐based Empirical Approach*

This paper provides empirical evidence on the dynamic effects of uncertainty on firm‐level capital accumulation. A novelty in this paper is that the firm‐level uncertainty indicator is motivated and derived from a theoretical model, the neoclassical investment model with time to build. This model also serves as the base for the empirical work, where an error‐correction approach is employed. I find a negative effect of uncertainty on capital accumulation, both in the short run and the long run. This outcome cannot be explained by the model alone. Instead, the results suggest that the predominant mechanism at work stems from irreversibility constraints.     

The Structure and Management of Alliances: Syndication in the Venture Capital Industry*

abstract Syndicates are a form of inter‐firm alliance in which two or more venture capital firms co‐invest in an investee firm and share a joint pay‐off. Syndication is a significant part of the venture capital market yet little research has been conducted into the process of structuring syndicate deals and the management of syndicates following deal completion. This paper analyses the neglected issues concerning the structuring and management of syndicated venture capital investments from the perspectives of both lead and non‐lead syndicate members using two surveys of venture capital firms and examination of syndication documents. Lead investors typically have larger equity stakes and the syndicated investment agreement is a document that enshrines the rights of participants rather than specifying behaviour. Contractual arrangements typically serve as a back drop to relationships as non‐legal sanctions are important and decisions are typically reached following discussion and consensus, but lead venture capital investors’ residual and specific powers are important in ensuring timely decision‐making. The findings extend previous work on alliances by emphasizing the importance of non‐legal sanctions, especially reputation effects, in mitigating opportunistic behaviour by dominant equity holders. The paper also adds to the limited research on the dynamics of alliances by highlighting the role of repeat syndicates.     

A keynesian macro-econometric model of the UK: 1955–1984

In this paper we present a small Keynesian macro-economic model in which wage-price determination is linked to the working of goods and money markets. By explicitly treating the Keynes effect we derive a general expression for the employment-money supply elasticity, and draw the IS-LM loci in the employment-interest rate space Our empirical specification allows for short-run disequilibrium dynamic adjustments around the static long-run relations predicted by the theoretical model. By careful use of our specification search strategy we obtain a statistically sound econometric model, which exhibits sensible long-run properties. A remarkable finding implied by our estimates is that equilibrium unemployment is negatively affected by both money supply and incomes policy.     

The firm under uncertainty: real and financial decisions

This paper examines the interplay between the real and financial decisions of the competitive firm under output price uncertainty. The firm faces additional sources of uncertainty that are aggregated into a background risk. We show that the firm always chooses its optimal debt–equity ratio to minimize the weighted average cost of capital, irrespective of the risk attitude of the firm and the incidence of the underlying uncertainty. We further show that the firm’s optimal input mix depends on its optimal debt–equity ratio, thereby rendering the interdependence of the real and financial decisions of the firm. When the background risk is either additive or multiplicative, we provide reasonable restrictions on the firm’s preferences so as to ensure that the firm’s optimal output is adversely affected upon the introduction of the background risk.     

Corporate Capital Budgeting Decisions and Information Sharing

Firms must overcome agency and information asymmetry problems to make efficient corporate capital budgeting decisions; this is particularly true for firms with multiple units dispersed across geographic locations. Internal communication and coordination may therefore be crucial in reducing information asymmetry and achieving efficient resource allocation. We examine the relationship between corporate capital budgeting decisions and the degree of internal information sharing using a dataset of 342 U.S. firms from 1993 to 2002. Information sharing is measured by the internal linkages observed in firms’ research and development activities worldwide. The efficiency of a firm's capital budgeting decisions is measured by the deviation of the firm's estimated marginal q from the theoretical tax‐adjusted benchmark. We observe a significant relationship between value‐enhancing capital budgeting decisions and stronger internal linkages. Specifically, corporate overinvestment is significantly reduced with better information sharing across units. All results are robust to firm‐ and industry‐level controls.     

Capital Structure and Labour Demand: Investigations Using German Micro Data

The paper analyses the interaction between capital structure and employment decisions of firms. For this purpose, a theoretical model is developed in which a firm determines employment along an optimal path taking into account financial considerations. The empirical analysis using West German micro data proves that a negative relationship exists between employment and the debt asset ratio of the firm. We also demonstrate that as real wages (sales) increase, employment decreases (increases).     

Exchange Rates,Non-Traded Goods and the Terms Of Trade: An Empirical Application for New Zealand

This article formulates and tests for New Zealand a model of exchange rate determination focusing on non-tradeable goods and terms-of-trade shifts. We emphasize the equilibrium properties of this framework and, in this context, estimate an error correction model where adjustment in response to deviation from equilibrium is an important determinant of short-run exchange rate movements. We estimate the model using a new data series on the supply of non-tradeable goods. The model has desirable empirical characteristics, including a plausible error correction equation, strong support for cointegration and rapid convergence to the long-run equilibrium. Moreover, a variety of diagnostic statistics, including parameter stability tests andout-of-sample forecasting performance, indicate the equation is a parsimonious representation of the data. These results provide considerable support for the emphasis on ‘real’ determinants of nominal exchange rates, in this case fluctuations in non-traded goods supply and terms-of-trade.
