multi resource investment strategies operational hedging under demand uncertainty abstract consider a firm that markets multiple products each manufactured using several resources representing various types of capital and labor and a linear production technology the firm faces uncertain product demand and has the option to dynamically readjust its resource investment levels thereby changing the capacities of its linear manufacturing process the cost to adjust a resource level either up or down is assumed to be linear the model developed here explicitly incorporates both capacity investment decisions and production decisions and is general enough to include reversible and irreversible investment the product demand vectors for successive periods are assumed to be independent and identically distributed the optimal investment strategy is determined with a multi dimensional newsvendor model using demand distributions a technology matrix prices product contribution margins and marginal investment costs our analysis highlights an important conceptual distinction between deterministic and stochastic environments the optimal investment strategy in our stochastic model typically involves some degree of capacity imbalance which can never be optimal when demand is known

fast high precision decision rules for valuing manufacturing flexibility abstract the valuation of flexible manufacturing systems is one of the most frequently undertaken productivity improvement activities in practice the introduction of an fms into industry must be done on the basis of cost justification recently developed techniques for the evaluation of the value of flexibility typically include the computation of stochastic dynamic programs however the computational effort of stochastic dynamic programs grows combinatorially and limits application to real world problems in this contribution we derive fast approximations to the stochastic dynamic program and compare their results to the exact solution the proposed methods show an excellent worst case behavior 1 for a wide range of volatility of the underlying stochastic profit margins and costs for switching the production mode the computational effort is reduced by a factor of more than 200

the irrelevance of capital structure for the impact of inflation on investment studies concerning the effect of inflation on firms investment decisions suggest that the form of financing is relevant in assessing the effect of inflation on investment this paper demonstrates that when the equilibrium relationship between market rates of return on bonds and stocks is considered the effect of inflation on investment is independent of the capital structure the paper also shows that when the fisher effect is assumed to hold the cut off rate of return on investment declines with anticipated inflation independently of the financing however if the real interest rate rises with inflation inflation may increase the cut off rate corporate investment decisions are affected by inflation because the tax code does not provide perfect adjustments for inflation real tax payments may vary with the inflation rate even if fully anticipated inflation does not affect other pre tax real flows three such effects have been commonly discussed in the literature first the real tax shield on depreciation decreases with inflation because depreciation allowances for tax purposes are based on historical costs rather than on current nominal values this depreciation effect causes the pretax required real rate of return on investments to rise with the rate of inflation second the real tax subsidy on interest deductions increases with inflation because firms are allowed to deduct interest expenses at nominal rates rather than at real rates if the interest rate does not rise with inflation sufficiently to offset the increased tax shelter the cut off rate of return tends to decrease with inflation this effect is termed in this paper the interest effect the third effect the capital gains effect may occur when inflation induced nominal capital gains on assets are subject to capital gains tax however since firms do not pay capital gains tax unless the asset is sold these tax payments are deferred the present value of these payments is presumed to be small and therefore the

stock market returns and inflation evidence from other countries this paper investigates the relation between common stock returns and inflation in twenty six countries for the postwar period our results do not support the fisher hypothesis which states that real rates of return on common stocks and expected inflation rates are independent and that nominal stock returns vary in one to one correspondence with expected inflation there is a consistent lack of positive relation between stock returns and inflation in most of the countries

investment and capacity choice under uncertain demand this paper extends the real options literature by discussing an investment problem where a firm has to determine optimal investment timing and optimal capacity choice at the same time under conditions of irreversible investment expenditures and uncertainty in future demand after the project is installed with a certain maximum capacity this capacity is fixed as an upper boundary to the output and cannot be adjusted later on it turns out that in the framework of this once and for all decision uncertainty in future demand leads to an increase in optimal installed capacity but on the other hand it causes investment to be delayed to an extent that even small uncertainty makes waiting and accumulation of further information the optimal decision for large ranges of demand limiting the capacity which may be installed weakens this extreme effect of uncertainty

multinational corporations vs domestic corporations international environmental factors and determinants of capital structure this paper examines whether or not u s based multinational corporations mncs have different capital structures than u s domestic corporations dcs and if so what causes the differences in explaining the difference between the capital structures of mncs and dcs previous studies tended to directly discuss the relationships between international environmental factors e g political risk foreign exchange risk and the capital structure a framework of analysis is proposed in this paper that examines the influence of environmental factors on the firm related capital structure determinants e g agency costs bankruptcy costs that in turn affect the capital structure of the mnc among the determinants that are examined more emphasis is placed on the discussion of agency costs since no previous studies have applied this concept in the international arena empirical tests were conducted to investigate whether mncs are significantly different from dcs regarding agency costs of debt bankruptcy costs and capital structure contrary to conventional wisdom the empirical findings show that mncs do not have lower bankruptcy costs and that they tend to have lower debt ratios than dcs

a strategic analysis of flexible manufacturing systems abstract in this paper a game theoretic model is presented by which investment in flexible manufacturing systems fms is analyzed if the investment in this innovative production system is viable due to either revenue enhancements or cost reductions the result is a competition for the first move among similar firms in an oligopolistic industry as a result the schumpeterian hypothesis of investment in a technological innovation occuring within an industry by swarms appears to apply to fms diffusion empirical evidence supporting the results of the theoretical analysis is presented

on the effects of barriers to international investment a simple model is presented in which it is costly for domestic investors to hold foreign assets the implications of the model for the composition of optimal portfolios at home and abroad are derived it is shown that all foreign assets with a beta larger than some beta plot on either one of two security market lines some foreign assets with a beta smaller than are not held by domestic investors even if their expected return is increased slightly while it is obviously not true that asset markets are completely segmented between countries there is evidence of barriers to international investment although reality seems to lie in that grey area between complete segmentation and no segmentation at all most international asset pricing models are concerned with the extreme case of no barriers to international investment no effort seems to have been made to study the effect on portfolio choice of such barriers which make it costly to hold foreign securities as opposed to domestic securities but which do not in general render international diversification so onerous that investors avoid foreign securities completely casual empiricism suggests that models without barriers to international investment should be suspect those models cannot explain why it appears that in every country investors on average hold more domestic securities than would be required if they held the world market portfolio 2 this paper constructs a model of international asset pricing in which there is a cost associated with holding either long or short risky foreign securities for the sake of simplicity in most of the paper we assume that while domestic investors face barriers to international investment foreign investors face no such barriers it turns out that nothing significant is lost with such an assumption the main conclusions of this paper for the case in which foreign investors face no barriers to international investment are 1 in the presence of barriers to international investment some risky foreign

compositional effects of capital controls theory and evidence this paper examines the effects of capital controls on the composition of inter national capital flows paying particular attention to debt inflows versus equity inflows a two period small open economy model with stochastic second period output and asymmetric information between domestic agents and international financiers is utilised to generate predictions regarding the effects of capital controls on the relative use of debt versus equity for financing first period investment these capital control implications are then investigated with quarterly frequency panel data for latin america capital controls are found to significantly affect the composition of the capital account

analysis and algorithm for the optimal investment times of new manufacturing technologies in a duopoly abstract on the basis of a dynamic and non cooperative game theoretic model the optimal timings of investments in new manufacturing technologies nmt is analysed under duopolistic competition non identical incumbents with time proportional demand always wait for some delay to invest in nmt the existence of silent timing equilibrium is addressed subsequently we show that cost reducing nmt diffuse over time within a duopoly the investments in strategic nmt however may be distributed through time or in a swarm economic interpretations of initial options and the comparative statics presented in this paper help decision makers develop strategies and make decisions under the situation they face finally a computational algorithm of optimal timings could verify this analysis and facilitate the real applications of game theoretic models

the relation between stock prices and inflationary expectations the international evidence this paper provides empirical evidence on the relation between stock returns and inflationary expectations for nine countries over the period 1971 80 the fisherian assumption that real returns are independent of inflationary expectations is soundly rejected for each major stock market of the world using interest rates as a proxy for expected inflation our data provide consistent support for the geske and roll model whose basic hypothesis is that stock price movements signal negative revisions in inflationary expectations finally a weak real interest rate effect was found for some of these countries

international capital structure equilibrium this paper develops a theory of capital structure in an international setting with corporate and personal taxes we generalize the miller analysis to an international equilibrium characterized by differential international taxation and inflation in otherwise perfect international capital markets our analysis highlights the key role that corporate tax arbitrage plays in generating an international capital structure equilibrium and we set forth a number of mechanisms for tax arbitrage transactions we close the paper by outlining some implications of our analysis for national differences in capital structure the international fisher effect and international tax effects on yield differentials among major questions regarding corporate capital structure which arise in an international setting are how or whether multiple tax jurisdictions and multiple currencies affect firm financing decisions and the international bond market equilibrium we examine some of these questions by way of generalizing miller s 1977 debt and taxes model into an international setting this setting allows for different tax regimes across countries as well as the possibility of differential inflation across currencies with consequent exchange rate movements in the first part of this paper we find that an international miller type equilibrium obtains under differential international taxation with capital market conditions which are otherwise analogous to those required for a domestic miller equilibrium our analysis particularly highlights the role that corporations play in miller s analysis as vehicles for tax arbitrage we show that if corporations engage in international tax arbitrage transactions on an equal footing no optimal capital structure exists for individual firms consequently without further restrictions differences in international tax rates alone are incapable of dictating a particular capital structure for an individual firm in the second part of the paper we extend the analysis to consider differential inflation rates with a consequent exchange rate movement and draw additional implications for the international analog of the miller equilibrium with differential inflation and taxation we begin by showing the existence of the international fisher effect for both equity and bonds although inflation and or exchange rate movements may affect real corporate tax subsidy rates and real

long term capacity decisions in uncertain markets for advanced manufacturing systems incorporating scope economies abstract by examining the literature in the field of manufacturing flexibility many researchers have located several form of flexibility by distinguishing them into strategic and operational flexibility forms furthermore many measures and design methods have been proposed for flexible manufacturing systems surely scope economies are one of the most important strategic form of flexibility in manufacturing systems and their strategic impact has been acknowledged by the very beginning of the flexible manufacturing era however despite several researches are available to address scope economies measurement and design methodologies very few researches investigate their economic convenience in front of dedicated manufacturing systems depending on the competitive market conditions this paper proposes a theoretical model whose main aim is the general understanding of the convenience conditions of scope economies based manufacturing systems the results of the theoretical model are very interesting because they locate market conditions that make scope economies manufacturing systems less profitable than dedicated manufacturing ones moreover the proposed model sets some general criteria to guide the entrepreneur in making right investment decision regarding this kind of manufacturing investments such results can explain the reason of many failures of flexible manufacturing systems and it suggests the use of this kind of approach to investigate other flexibility forms of manufacturing systems the ultimate goal of this research is the construction of a decision support system for supporting the entrepreneur in making decision on advanced manufacturing systems investment decisions

multinational capital structure and financial flexibility abstract we address multinational capital structure decisions when firms have varying degrees of financial flexibility for shifting income and or tax shields between subsidiaries we find 1 firms can use leverage to dramatically reduce negative valuation effects from operating in a high tax country 2 financial flexibility is a key determinant of optimal capital structure acting as both a substitute and a complement for leverage 3 multinational firms derive a synergistic effect from financial flexibility which can enhance their value beyond that for a single country firm from a low tax jurisdiction and 4 optimal capital structure typically differs substantially across subsidiaries with each having positions in multiple currencies

debt taxes and international equilibrium abstract this paper employs an extended miller model to analyze capital structure decisions of individual firms in a two country setting miller equilibria are generally not consistent with an international equilibrium if the tax subsidy of debt differs across countries the most obvious reason for differential tax subsidies is differences between national corporate tax rates we also identify differential tax subsidies of debt if inflation rates differ across countries for both cases we examine the adjustment process from national equilibria to an international equilibrium without and with barriers to international investment we derive the relationship between the equilibrium yields on debt and equity in the two countries and discuss the fisher hypothesis that real returns do not depend upon inflation in a two country miller world

capital budgeting investment project valuation and financing mix methodological proposals abstract a firm using a discount rate defined at the corporate scale as a weighted average cost of capital wacc may have to value projects subject to a different tax rate from the one used to calculate its discount rate moreover to determine the economic value of a project the wacc and arditti levy methods need to be adjusted if the firm allocates to this project a loan representing proportionally more or less than the fraction corresponding to the target debt ratio defined by the firm for projects in the same class of risk we first propose a method which corresponds to the adjustment of standard wacc calculations the formulation adopted generalized atwacc method has the advantage of being independent of any consideration related to debt ratios we then develop a consistent adaptation of the arditti levy method adapted btwacc method but it does not possess the simplicity of that of the generalized atwacc method

the effects of capital controls on international capital flows in the presence of asymmetric information abstract this paper examines the effects of capital controls on the volume and composition of international capital flows in the presence of asymmetric information in the two period small open economy model stochastic second period output depends on the level of first period investment which cannot be verified by international investors domestic agents obtain external funding by borrowing on international capital markets and by selling equity to international investors the paper investigates the effects of various capital controls on the debt equity choice domestic investment and welfare controls on capital inflows are shown to shift the composition of flows from fixed income instruments towards equity and to reduce the overall volume of inflows

optimal investment in product flexible manufacturing capacity this paper presents a model and an analysis of the cost flexibility tradeoffs involved in investing in product flexible manufacturing capacity flexible capacity provides a firm with the ability to respond to a wide variety of future demand outcomes but at the expense of the increased cost of acquiring flexible manufacturing capacity as compared with dedicated or nonflexible capacity we formulate the product flexible manufacturing capacity investment decision as a two stage stochastic program in the first stage the firm must make its investment decision in manufacturing capacity before the resolution of uncertainty in product demand in the second stage after demand for products are known the firm implements its production decisions constrained by the first stage investments the main contributions of this paper are threefold first we develop a model of the firm s flexible manufacturing investment decision that conceptually captures some of the key characteristics of this complex decision probl

developing an input output activity matrix ioam for environmental and economic analysis of manufacturing systems and logistics chains abstract an activity matrix am shows the activities that transform an organization s inputs into outputs the inputs are the system targets and the materials energy and other resources that are used to achieve these the outputs are the system performance expressed in terms of production quality profit environmental performance waste etc performance may be measured against the financial environmental technical social or other system targets a concurrent enterprise view is used to represent the manufacturing system activities and the paper examines how an am may be used to represent and design systems two kinds of am are examined an unconstrained activity matrix and an input output activity matrix ioam with an unconstrained am the system designer chooses system outputs attributes or requirements intuitively this provides great flexibility and allows e g the social and organisational implications of proposed changes to be investigated the inputs are not formally stated although a systems designer normally focuses on identifying the stages of a product life cycle and analysing their impact on the system s outputs the main emphasis of the paper is on the ioam and its use to represent the transformation of an organization s inputs into outputs the input output representation developed in the paper is used to examine manufacturing and logistics systems first the ioam is used to represent a manufacturing system as one tier of a logistics chain and its performance secondly the ioam representations may be derived for a multi tier system to represent its production economic and environmental performance

costing an international public good the case of the baltic sea abstract the paper discusses an economically efficient and internationally equitable provision of a specific public good the good in question the baltic sea satisfies a number of needs but economic values implied may be different in various countries polluting and using the sea the level of eutrophication has been identified as a key characteristic of the baltic sea relevant for its value the chander tulkens model of cost sharing is used to determine a hypothetical allocation of abatement costs across the countries around the sea the application of the model is based on estimates of national abatement costs as well as national willingness to pay for reduced eutrophication estimating willingness to pay in a collection of countries some of which undergo a transition from centrally planned systems has been the main challenge of this study the results were derived from a coordinated series of contingent valuation surveys in lithuania poland and sweden combined with benefit transfer studies to cover the rest of the region predictions of cost sharing schemes obtained from the chander tulkens model are confronted with actual data on abatement expenditures and international assistance several recommendations on how to optimize the baltic wide programmes conclude the paper
