the cournot and bertrand outcomes as equilibria in a strategic metagame is fully variable in the short run so that if one firm is undercut by another the lower priced firm can expand output to serve all the demand it is this basic insight that we explore we present a general model in which the flexibility of production is endogenous and which embraces both the cournot and bertrand outcomes as possibilities this enables us to see which outcomes will emerge from firms strategic decisions rather than presupposing either in this paper the flexibility of production is determined by the factors of production that the firm precommits output is produced by two factors of production capital and labour there are two stages to the model in the first strategic stage the firm will precommit one both or neither of its factors of production in the second market stage a competitive equilibrium occurs the price clears the market given firms supply functions thus the firm s decision in the strategic stage determines the supply function that the firm has in the market stage there are three possible types of precommitment for the firm a total precommitment the firm precommits both inputs and hence capacity b strategic investment the firm precommits one factor of production capital leaving the other labour freely variable in the market stage c no precommitment the firm is free to vary the level of both factors of production in the market stage in the case of total precommitment the firm will have a

analzying trade offs between machine investment and utilization analyzing machine investment opportunities from a systems perspective requires an understanding of interdependencies between machine investment and utilization decisions machine investment decisions involve determining the number of machines to purchase and their types machine utilization decisions involve determining part allocations and production cycles interdependencies between these decisions result in trade offs between investment and operating costs this paper develops an analytical approach for studying machine investment opportunities in a broad systems context it begins with a discussion of the interdependencies between investment and utilization decisions the focus of this research and a review of existing literature related to machine investment decisions are then discussed next a mathematical model that quantifies these interdependencies is formulated the paper ends with a simple example that demonstrates the usefulness of the model and highlights the importance of using a systems app

costs and benefits of investment in electronic design abstract appraising any investment requires reliable quantification of the costs and benefits associated with the project this paper addresses the measurement of the value of investment in design in electronic industries it discusses a staged approach to the measurement of costs and benefits within the design activity itself and resulting from changes in downstream activities in manufacturing and test it considers the problems of estimating revenues resulting from strategic implications of investment in design and suggests a possible approach to evaluating those benefits difficult to quantity

flexibility and uncertainty the preserving of flexibility when faced with uncertainty is a neglected aspect of behaviour under risk yet it is an important factor in decisions to hold liquid assets or delay irreversible investment this paper formalizes the notion of flexibility in a sequential decision context and relates its value to the amount of information an agent expects to receive a rudimentary money demand model is developed embodying these ideas and the history of flexibility as an economic concept is traced choices are frequently made between alternatives that imply different degrees of future commitment between a short term investment that leaves future options open for example and a long term one that by its very nature forecloses those options the relative attractiveness of the two depends on their probability distributions of payoffs over time a basic consideration in this choice is the recognition that beliefs about the risks governing these payoffs may change current doubts may be partially resolved in the near future this prospect decreases the attractiveness of the longer term commitment in that one is able to respond less fully to new information and even if it does not directly affect the risks associated with shorter term choices enhances their appeal this paper formalizes the above remarks by establishing connections between the following two partial orderings the first is an ordering based on variability of beliefs one set of beliefs is more variable than another if more final risk is resolved at an intermediate stage the more one expects to learn by an intermediate period relative to what one knows today the more variation one is anticipating in beliefs about the final outcome the second is an ordering of current actions or positions based on flexibility one position is more flexible than another if it leaves available a larger set of future positions at any given level of cost these two orderings are incorporated in a simple sequential decision model to suggest the following behavioural principle the more variable are a decision maker s beliefs the more flexible is the position he will choose this principle potentially applies whenever i there will be opportunities to act after further information is received and ii current actions influence either the attractiveness or availability of different future actions

flexible manufacturing uncertain consumer tastes and strategic entry deterrence this paper investigates the strategic use of flexible manufacturing technology as an entry deterring mechanism it is shown that when consumers tastes fluctuate probabilistically an incumbent threatened with potential entry installs flexible manufacturing technology for a larger set of probabilities that consumers tastes will change than the perfectly protected monopolis t the differential probability sets represent the intent of the monopo ly incumbent strategically to use product design flexibility for deterr ing entry into the potential market and maintain its dominance under fluctuating consumer tastes this purely preemptive flexibility is shown to exist under reasonable assumptions on the firms payoff structure copyright 1993 by blackwell publishing ltd

production technologies and technical efficiency evidence from portuguese manufacturing industry this paper aims to test whether a given type of process innovation namely flexible production technologies fpts contributes to increased firm efficiency using one year firm data from the portuguese manufacturing industry and applying a parametric stochastic frontier approach individual technical efficiencies are obtained and their determinants simultaneously estimated using a single step procedure recently proposed by battese and coelli 1995 the results support the hypothesis that technological flexibility measured through the use of fpts is important in explaining differences in efficiency furthermore given the specifications of the stochastic frontier function the null hypothesis that portuguese firms are fully technically efficient is rejected

prices vs quantities the effects on technology choice abstract it is well known that price and quantity based regulation approaches provide different investment incentives but usually only the effect on the level of investment is studied in this paper we show that under uncertainty they also lead to the adoption of different technologies due to the disparate risks that a regulated firm is exposed to different regulatory instruments induce different technologies and this effect cannot be compensated by varying the design of the instruments furthermore price based instruments lead to the adoption of a socially suboptimal technology so that the inclusion of technology choice provides a bias in favor of a quantity based regulation compared with weitzman s weitzman m l 1974 prices vs quantities review of economic studies 41 477 491 criterion

flexible capacity strategy with multiple market periods under demand uncertainty and investment constraint abstract we establish a flexible capacity strategy model with multiple market periods under demand uncertainty and investment constraints in the model a firm makes its capacity decision under a financial budget constraint at the beginning of the planning horizon which embraces n market periods in each market period the firm goes through three decision making stages the safety production stage the additional production stage and the optimal sales stage we formulate the problem and obtain the optimal capacity the optimal safety production the optimal additional production and the optimal sales of each market period under different situations we find that there are two thresholds for the unit capacity cost when the capacity cost is very low the optimal capacity is determined by its financial budget when the capacity cost is very high the firm keeps its optimal capacity at its safety production level and when the cost is in between of the two thresholds the optimal capacity is determined by the capacity cost the number of market periods and the unit cost of additional production further we explore the endogenous safety production level we verify the conditions under which the firm has different optimal safety production levels finally we prove that the firm can benefit from the investment only when the designed planning horizon is longer than a threshold moreover we also derive the formulae for the above three thresholds

bequest motives and determinants of micro life insurance in sri lanka this paper emphasizes bequest motives by evaluating participation patterns in micro life insurance against insurance demand and supply side factors based on household survey data from sri lanka it presents evidence on the determinants of micro life insurance participation of low income households using probit and tobit models the results provide evidence that micro life insurance is positively correlated with measures of bequest motives such as the number of children or dependents besides better off households are less excluded from micro life insurance markets than their poorer counterparts the study finds a convincing need for the microinsurance sector to be more responsive to the needs of the poor with a key role in providing financial education to understand the need for microinsurance

product innovation a tool for competitive advantage abstract this paper assesses the overall contribution of product innovation to competitive advantage analyzes the conditions under which such a contribution is likely and discusses how this likelihood can be increased through company action it concludes that pioneering is not riskier than following and that successful pioneers enjoy substantial and lasting competitive advantages success depends on the innovation s relative advantage compatibility complexity and the strength of the accompanying marketing effort lead time allows pioneers to build up resources that contribute to sustainability but customer and technological changes may destroy the competitive value of these resources

flexibility and firm diversity with demand fluctuations abstract this paper examines how demand induced output fluctuations are distributed by competitive firms within industries it shows that competitive equilibria in fluctuation prone industries may support technologically diverse firms some firms are more flexible than others and absorb a disproportionate share of industrywide output fluctuations others are less flexible and have output levels more stable than the industry as a whole their coexistence in competitive equilibrium is due to a tradeoff between flexibility and static efficiency within the discrete set of available production technologies

optimal production strategy under demand fluctuations technology versus capacity abstract this paper provides a comparative analysis of five possible production strategies for two kinds of flexibility investment namely flexible technology and flexible capacity under demand fluctuations each strategy is underpinned by a set of operations decisions on technology level capacity amount production quantity and pricing by evaluating each strategy we show how market uncertainty production cost structure operations timing and investment costing environment affect a firm s strategic decisions the results show that there is no sequential effect of the two flexibility investments we also illustrate the different ways in which flexible technology and flexible capacity affect a firm s profit under demand fluctuations the results reveal that compared to no flexibility investment flexible technology investment earns the same or a higher profit for a firm whereas flexible capacity investment can be beneficial or harmful to a firm s profit moreover we prove that higher flexibility does not guarantee more profit depending on the situation the optimal strategy can be any one of the five possible strategies we also provide the optimality conditions for each strategy

price adjustment costs and the effect of endogenous technique on price stickiness abstract this paper analyzes a monopolistic firm s pricing and choice of technique decisions when it faces a random demand and must incur a fixed menu cost to adjust its price to demand shocks we show that price adjustment costs have the same effect as an increase in the variability of demand in that the firm will choose a technique yielding a flatter short term marginal cost curve making the production technique endogenous widens the range of demand shifts that will be accommodated with an unchanged price it allows for less price variation and more quantity variation when it is profitable to pay the menu cost and adjust the price

competitive incentives for manufacturing flexibility abstract a game theoretic model is used in this paper to analyze firms incentives to acquire product flexibility the degree of product flexibility is determined by the cost a firm must incur to produce a new product the model helps to identify characteristics of industries which are likely to encourage product flexibility strategies the model suggests that firms in industries where the ratio of price to variable cost is high are likely to expend more effort to increase product flexibility this hypothesis is then tested empirically

racial disparities in life insurance coverage we evaluate the extent to which there are racial disparities in life insurance coverage using multiple years of the survey of income and program participation between 2001 and 2010 we find that african americans hold significantly more life insurance after controlling for other factors especially employer sponsored and whole life insurance we demonstrate that our findings diverge from prior work because we examine all households instead of focusing exclusively on married and cohabitating households the findings on life insurance coverage and composition imply that earnings shocks due to mortality are not a contributing factor to racial disparities in wealth

the family as an incomplete annuities market families can self insure against uncertain dates of death through implicit or explicit agreements with respect to consumption and interfamily transfers interfamily transfers need have nothing to do with altruistic feelings they may simply reflect risk sharing behavior of completely selfish family members although family annuity markets are incomplete even small families can substitute by more than 70 percent for perfect market annuities given adverse selection and transaction costs family risk pooling may be preferred to public market annuities in the absence of public annuities these risk sharing arrangements provide powerful incentives for marriage and family formation

entrepreneurial strategy and the presence of small firms a model is presented hypothesizing that the level of small firm presence in any given industry emanates from the exogenous stock of entrepreneurial talent a stochastic element of managerial and entrepreneurial talent entry deterrence and the entrepreneurial strategy deployed by small firms using data newly released by the u s small business administration the hypothesis is tested for a sample of 247 four digit standard industrial classification industries spanning the entire spectrum of firm sizes we find that consistently for all the measures of small firm size and for all of the time periods used the existence of entry deterrence and reliance upon innovative strategy explains a significant proportion of the variation in the presence of small firms

dynamic optimal control of process product innovation with learning by doing abstract in this paper we present a dynamic optimal control model of process product innovation with learning by doing and extend the model of chenavaz 2012 to an even more general model in which the firm s cost functions of product and process innovation depend on both the innovation investments and the knowledge accumulations of product and process innovation furthermore in our paper the product price the investments of product and process innovation are decision variables the product quality production cost the change rates of knowledge accumulations of product and process innovation are state variables the main objective of this paper is to analyze the relationships between these variables and investigate the model s optimal conditions and characteristics further we solve the model with some numerical examples and sensitivity analysis is conducted to study the effect of changing the parameters and coefficients on the objective function value

intraconnectivity and interconnectivity when value creation may reduce profits this paper analyses firms decisions to provide connectivity to their customers we distinguish between intraconnectivity the ability of one firm s customers to connect to each other and interconnectivity the ability of one firm s customers to connect with another firm s customers the profitability implications of allowing connectivity are not a straightforward consequence of the consumer value of connectivity because connectivity affects not only the customer value but also the intensity of competition by creating or changing network externality we find that if sales are driven by brand switching rather than by category expansion a firm may find it optimal not to provide intraconnectivity even if providing it is not costly and may find it optimal to provide interconnectivity even at a cost exceeding the consumer value of connectivity on the other hand if category expansion is possible providing intraconnectivity may be profitable in this case either the equilibrium intraconnectivity provision may be asymmetric or both firms may find it individually optimal to provide intraconnectivity under certain conditions in the latter case the firms choice of intraconnectivity is a prisoner s dilemma game

inventory cost rate functions with nonlinear shortage costs this article considers five cost rate models for inventory control each summarizing the expected holding and shortage costs per period as a function of the inventory position all models have linear holding costs and shortage cost coefficients of dimension unit period unit and period the latter two coeficients may be the shadow costs of a fill rate and a ready rate service constraint respectively one of the cost rate models is a new suggestion intended to facilitate modeling of periodic review inventory systems if and only if conditions on the demand process are presented for which the cost rate is quasi convex in the inventory position the typical sufficient condition requires that the cumulative demand distribution be logconcave a condition that is met by most demand distributions commonly used in the inventory literature the results simplify optimization and extend the known optimality of s s and nq r policies to cost structures common in applications and to the presence of typical service constraints as a prerequisite for the study a series of new monotonicity results are derived for compound renewal processes

the mismatch between life insurance holdings and financial vulnerabilities evidence from the health and retirement study using data on older workers from the 1992 health and retirement survey along with an elaborate life cycle planning model the authors quantify the effect of each individual s death on the financial status of his or her survivors and the degree to which life insurance holdings moderate these consequences the average change in living standard that would result from a spouse s death is small both in absolute terms and relative to the decline that would occur without insurance however this average obscures a startling mismatch between insurance holdings and underlying vulnerabilities for many of the most vulnerable the amounts purchased are surprisingly small and for many of the least vulnerable the amounts are surprisingly large as a result uninsured vulnerabilities are quite widespread the magnitude of these vulnerabilities as well as the proclivity to address any given degree of vulnerability by purchasing life insurance vary systematically with individual and household characteristics

flexibility and the theory of the firm abstract the object of this paper is 1 to bring together and integrate the various concepts of flexibility found in the economic literature 2 to flesh out the meaning of various aspects of flexibility and their implications thereby bridging the gap between the existing highly abstract theories and the empirical facts and 3 in the process to give a rich and comprehensive enough description of an industry to stimulate further theoretical as well as empirical work the study tries to combine inductive and deductive reasoning using empirical observations based on indepth interviews with manufacturers in the metalworking industry in the united states and sweden

demand fluctuations and firm heterogeneity this paper reports evidence supporting the hypothesis that production flexibility is one of the forces that explain differences in the distribution of firm sizes across industries using a data set composed of annual observations on 163 four digit manufacturing industries over the period 1978 88 the authors find a negative relationship between market share and sales variability this empirical result suggests that large and small fir ms each have their own efficiency niches while large firms enjoy the advantage of static production efficiency the flexible production technologies of small firms enable them to respond better to changin g demand conditions copyright 1993 by blackwell publishing ltd

strategic aspects of flexible production technologies theory and evidence abstract in this paper we examine the innovative manufacturing technologies known as flexible manufacturing systems fms we begin with a description of these systems and the industries in which they are used we then review several theoretical models which analyze the decision process to invest in fms these models illustrate the importance of such market factors as product differentiation differences in cost and market size degree of competition and market dynamics in the second part of the paper we present some new empirical evidence using a database of almost 3 000 business units this empirical evidence is shown to be consistent with the theory

life insurance and household consumption abstract using life insurance holdings by age sex and marital status we infer how individuals value consumption in different demographic stages we estimate equivalence scales and bequest motives simultaneously within a fully specified model where agents face us demographics and save and purchase life insurance our findings indicate that individuals are very caring for dependents that economies of scale are large that children are very costly or yield very high marginal utility that wives with children produce lots of home goods and that females display habits from marriage while men do not these findings contrast sharply with standard equivalence scales

did lower unionization in the united states result in more flexible industries do unions really impede manufacturers output flexibility if so in what ways the authors propose a methodology for quantifying george stigler s concept of output flexibility and for decomposing the effects of unionization on average cost differences between union and non union plants using a recently compiled data set on u s three digit manufacturing industries from 1973 to 1996 they adapt this methodology to simulate the effects of unionization on flexibility and average costs for average size plants simulation results indicate that higher unionization was associated with higher average costs and lower flexibility than low unionization higher average costs appear to have been primarily due to higher fixed costs such as higher benefits

human capital risk contract enforcement and the macroeconomy we use data from the survey of consumer finance and survey of income program participation to show that young households with children are under insured against the risk that an adult member of the household dies we develop a tractable macroeconomic model with human capital risk age dependent returns to human capital investment and endogenous borrowing constraints due to the limited pledgeability of human capital limited contract enforcement we show analytically that consistent with the life insurance data in equilibrium young households are borrowing constrained and under insured against human capital risk a calibrated version of the model can quantitatively account for the life cycle variation of life insurance holdings financial wealth earnings and consumption inequality observed in the us data our analysis implies that a reform that makes consumer bankruptcy more costly like the bankruptcy abuse prevention and consumer protection act of 2005 leads to a substantial increase in the volume of both credit and insurance

are life insurance holdings related to financial vulnerabilities using the 1995 survey of consumer finances and an elaborate life cycle model we quantify the potential financial impact of each individual s death on his or her survivors and measure the degree to which life insurance moderates these consequences life insurance is essentially uncorrelated with financial vulnerability at every stage of the life cycle as a result the impact of insurance among at risk households is modest and substantial uninsured vulnerabilities are widespread particularly among younger couples we also identify a systematic gender bias for any given level of financial vulnerability couples provide significantly more protection for wives than for husbands jel d10 g22

reduce shortage with self reservation policy for a manufacturer paying both fixed and variable stockout expenditure this study considers a single item make to stock system with continuous time production and inventory controls to meet bulk demand with an exponential inter arrival time a key issue in this system is the non convex shortage cost consisting of fixed and variable expenditures when the demand is not fully satisfied we propose a self reservation policy by building a markov decision process to minimize the overall cost we find that the optimal production control is still a base stock policy but the structure of the optimal self reservation policy is very complicated however if the effective outstanding variable shortage cost is sufficiently large the optimal self reservation policy has an easy form of reserve all or nothing our numerical examples indicate the optimal policy may reduce the total average cost by 47 on average

cross sectional estimation in marketing direct versus reverse regression empirical results in marketing research are often derived from linear additive models estimated on cross sectional data an underlying assumption of these model specifications is that each exogenous variable contributes an additive effect to the endogenous variable measuring these additive effects is problematic if some components of the endogenous variable are not observable to the researcher reliance on observable correlates to capture those aspects of the endogenous variable might require reverse regression to ensure unbiasedness of the estimated effects in contrast to direct regression used exclusively in marketing research reverse regression first estimates the effect of the endogenous variable on those correlates and then derives unbiased estimates of the additive effect of other exogenous variables specified in the basic model this paper discusses the reverse regression approach relying on recently published analytic results a statistically powerful and analytically simple test is developed which allows the marketing researcher to assess a priori whether direct or reverse regression will provide unbiased parameter estimates an empirical illustration focuses on the measurement of potential market share rewards for pioneering businesses contained in the pims data base other areas in marketing where the issue of direct versus reverse regression is pertinent are mentioned

cost flexibility and price dispersion this paper examines the relationship between a firm s cost flexibility and product price dispersion we show that a mean preserving increase in demand variability need not lead to an increase in the value of flexibility or in the optimal level of flexibility this is contrary to results in the literature which are achieved by assuming a quadratic cost curve in a pioneering paper stigler 1939 considered a firm s choice of plant flexibility he argued that if firms face exogenous demand fluctuations then it can be worthwhile to select a more flexible plant one which permits higher profit in a wide range of possible demand states at the cost of lower profit in other demand states stigler suggested that the desirability of a more flexible plant increases as price variability increases marschak and nelson 1962 explored this conjecture they showed that an increase in the variance of price causes expected profit from a more flexible plant to rise relative to expected profit from a less flexible plant more recently mills 1984 considered long run equilibrium in a competitive industry subject to fluctuating demand when firms can select a level of flexibility he showed that the optimal level of flexibility increases as the variance of demand increases the results of marschak and nelson and mills however are based on the strong assumption that the cost function is quadratic an assumption which is known to be restrictive in the analysis of decision making under uncertainty in this paper we generalize the analysis of cost flexibility in two ways first we adopt the rothschild stiglitz 1970 definition of increased price variability and show that the results of marschak and nelson and of mills continue to hold for a quadratic cost function second we relax the assumption that cost is a quadratic function of output and show that the results in the existing literature are crucially dependent on this assumption after formulating the model we consider the effect of an increase in price dispersion on the value of flexibility defined as willingness to pay then we examine the effect of increased price variability on the optimal level of flexibility finally we consider the impact of an increase in demand variability on the equilibrium in a competitive industry in all cases we find that the results in the literature continue to hold for a general mean preserving

capabilities as real options strategy research consists of a balance between positive and normative theory normative theories suggest particular heuristics or cognitive representations to find appropriate solutions heuristics permit faster solutions to real time problems they also suffer from the potential of negative transfer to inappropriate applications the theory of real options provides the appropriate heuristic framing of competencies and exploratory search a real options approach marries the theory of financial options to foundational ideas in strategy organizational theory and complex systems we join these approaches to identify three pairs of concepts scarce factor and the underlying asset in option theory inertia and irreversibility and the ruggedness of landscape and option values strategic theories of resources largely define a core competence as unique and nonimmutable in doing so this definition has wrongly forgotten barney s initial insight into scarce factor markets as determining the valuation of a competitive asset financial theory of real options derives its heuristics of investing in exploratory search by inferring future value of today s investments from market prices we apply the three conceptual pairs to the evaluation of capabilities as real options through a formal descriptive model the valuation of core capabilities is derived from observing the price dynamics of correlated strategic factors in the market because of inertia managers cannot easily adjust the wrong set of organizational capabilities to the emergence of market opportunities however firms that have made investments in capabilities appropriate to these opportunities are able to respond from this description we define core competence as the choice of capabilities that permits the firm to make the best response to market opportunities the heuristic framing of capabilities as real options guides the normative evaluation of the balance between exploitation and exploration

managing flexible capacity in a make to order environment flexible capacity has been shown to be very effective to hedge against forecast errors at the investment stage in a make to order environment this flexibility can also be used to hedge against variability in customer orders in the short term for that purpose production levels must be adjusted each period to match current demands to give priority to the higher margin product or to satisfy the closest customer however this will result in swings in production inducing larger order variability at upstream suppliers and significantly higher component inventory levels at the manufacturer through a stylized two plant two product capacitated manufacturing setting we show that the performance of the system depends heavily on the allocation mechanism used to assign products to the available capacity although managers would be inclined to give priority to higher margin products or to satisfy customers from their closest production site these practices lead to greater swings in production result in higher operational costs and may reduce profits

the economic effects of social security toward a reconciliation of theory and measurement abstract in this paper we argue that actuarial valuation of social security benefit streams is theoretically inconsistent with the assumption of pure life cycle motives instead we show that the simple discounted value of future benefits ignoring the possibility of death is often a good approximation to the relevant concept of value this observation motivates a re examination of existing empirical evidence concerning the economic effects of social security we focus our attention on studies of distributional equity and personal saving behavior in both cases we argue that the use of simple rather than actuarial discounting of survival contingent income streams produces results that differ dramatically from previous findings specifically estimates based on actuarial valuation may overstate the importance of redistribution between and within generations and may understate the depressive effect of social security on personal wealth accumulation by a factor of three or more

investment and market power abstract this paper argues that the degree of market power within an industry is an important determinant of interindustry differences in investment behavior a neoclassical investment model is analyzed to show that market power is positively associated with capital stock flexibility the intuition for the result is that firms adjust their stocks and investment plans quickly in response to new conditions so as to capture the rents asssociated with their market power

to own or not to own your life insurance policy abstract life insurance proceeds are generally subject to the estate tax an exception is when the policy is owned by the beneficiaries and the insured gives up ownership and control including the ability to change beneficiaries should the insured strategically own the policy contract and potentially subject proceeds to estate and inheritance taxes or relinquish control with the beneficiaries owning the policy and escape such transfer taxes this paper addresses how the estate tax influences the choice of life insurance ownership using samples of estate tax returns the empirical evidence suggests that those facing high estate tax rates are more likely to forgo ownership and have proceeds excluded from their estates and provides further evidence on the incentive effect of taxes and in support of the strategic bequest motive

the strategic perils of delayed differentiation the value of delayed differentiation also known as postponement for a monopolist has been extensively studied in the operations literature we analyze the case of imperfectly competitive markets with demand uncertainty wherein the choice of supply chain configuration i e early or delayed differentiation is endogenous to the competing firms we characterize firms choices in equilibrium and analyze the effects of these choices on quantities sold profits consumer surplus and welfare we demonstrate that purely strategic considerations not previously identified in the literature play a pivotal role in determining the value of delayed differentiation in the face of either entry threats or competition these strategic effects can significantly diminish the value of delayed differentiation in fact under plausible conditions these effects dominate the traditional risk pooling benefits associated with delayed differentiation in which case early differentiation is the dominant strategy for firms even under cost parity with delayed differentiation we extend the main model to study the effects of alternate market structures asymmetric markets and inventory holdback our results in particular that for a broad range of parameter values early differentiation is a dominant strategy even under cost parity with delayed differentiation are robust to these relaxations

strategic choice of flexible production technologies and welfare implications addendum et corrigendum in a recent article roller and tombak 1990 analyze the strategic choice of modern flexible production technologies they develop a two stage game in which firms choose between a flexible technology and a dedicated technology in the first stage and subsequently choose output this note corrects an error in one of the graphs in that paper provides an interpretation of the new graph and extends the analysis by allowing for mixed strategies and complementary products copyright 1992 by blackwell publishing ltd

the choice of technology and capital structure under rate regulation this paper examines a regulated firm s choice of technology it presents a model in which regulatory opportunism induces the firm to adopt a technology that gives rise to cost functions with higher variable costs and lower fixed costs than is socially optimal this distortion arises because the regulated price is positively correlated with marginal costs consequently a technology with low marginal costs implies a low regulated price and hence is unattractive to the firm debt financing is shown to alleviate this distortion because it induces regulators to increase the regulated price to prevent the firm from financial distress thereby reducing the cost to the firm of adopting technologies with low marginal costs when regulators restrict the firm s ability to issue debt the firm may have an incentive to goldplate i e waste resources this incentive disappears when the firm can use its most preferred mode of financing

competition and investment in flexible technologies this paper examines the implications of market structure on investment in flexible manufacturing systems fms we analyze a two stage game in which firms choose between a flexible and a less flexible technology in the first stage then choose production quantities in the second stage in equilibrium a large proportion of fms firms is associated with more concentrated markets our model predicts that a larger market and or a more differentiated product results in a higher proportion of fms firms being sustained these predictions are empirically supported using cross section industry level data from both the us and japan

annuities and individual welfare advancing annuity demand theory we present suffcient conditions for the optimality of full annuitization under market completeness that are substantially less restrictive than those used by yaari 1965 we examine demand with market incompleteness finding that positive annuitization remains optimal widely but complete annuitization does not how uninsured medical expenses affect demand for illiquid annuities depends critically on the timing of the risk a new set of calculations with optimal consumption trajectories very different from available annuity income streams still shows a preference for considerable annuitization suggesting that limited annuity purchases are plausibly due to psychological or behavioral biases

imitation costs and patents an empirical study it has long been recognised that the costs of imitating new products have an important effect on the incentives for innovation in a market economy as arrow i962 and others have pointed out if firms can imitate an innovation at a cost that is substantially below the cost to the innovator of developing the innovation there may be little or no incentive for the innovator to carry out the innovation in their discussions of the innovation process economists frequently have called attention to the major role played by the costs of imitation but there has been little or no attempt to measure these costs to test various hypotheses concerning the factors influencing them or to estimate their effects in this paper we report some findings of what seems to be the first study of this topic in addition we present data regarding the effects of patents on imitation costs and on the rate of innovation

strategic technology choice and capacity investment under demand uncertainty this paper studies the impact of competition on a firm s choice of technology product flexible or product dedicated and capacity investment decisions specifically we model two firms competing with each other in two markets characterized by price dependent and uncertain demand the firms make three decisions in the following sequence choice of technology technology game capacity investment capacity game and production quantities production game the technology and capacity games occur while the demand curve is still uncertain and the production game is postponed until after the demand curve is revealed we develop best response functions for each firm in the technology game and compare how a monopolist and a duopolist respond to a given flexibility premium we show that the firms may respond to competition by adopting a technology which is the same as or different from what the competitor adopts we conclude that contrary to popular belief flexibility is not always the best response to competition flexible and dedicated technologies may coexist in equilibrium we demonstrate that as the difference between the two market sizes increases a duopolist is willing to pay less for flexible technology whereas the decision of a monopolist is not affected further we find that a firm that invests in flexibility benefits from a low correlation between demands for two products but the extent of this benefit differs depending on the competitor s technology choice our results indicate that higher demand substitution may or may not promote the adoption of flexibility under competition whereas it always facilitates the adoption of flexibility without competition finally we show that contrary to intuition as the competitor s cost of capacity increases the premium a flexible firm is willing to pay for flexibility decreases

dedicated vs product flexible production technology strategic capacity investment choice this paper studies the optimal investment strategies of an incumbent and a potential entrant that can both choose between a product flexible and dedicated technology in a two product market characterized by uncertain demand the product flexible production technology has certain advantages especially when the economic environment is uncertain on the other hand the dedicated production technology allows a firm to commit to production quantities this gives strategic advantages which can outweigh the value of flexibility it turns out that both firms prefer for some scenarios the dedicated production technology however we find that in a game with sequential technology choices both firms investing dedicated will not be an equilibrium especially when the economic environment is more uncertain the incumbent overinvests in product flexible capacity to force the entrant to choose the dedicated technology then the incumbent is the only firm with the product flexible production technology which results in a high payoff

flexibility in the face of demand fluctuations employment capacity utilization and industry structure abstract this paper contributes to the theory of industry structure with fluctuating demand which was applied to us output and employment data by mills and schumann american economic review 1985 75 758 767 the paper extends the theoretical model and applies it to a unique set of german panel data of individual firms explaining fluctuations in employment and capacity utilization this contributes to the generally underinvestigated demand side of employment behavior

managerial efficiency and the schumpeterian link between size market structure and innovation revisited this research uses a unique survey on innovation conducted in belgian high tech industries to investigate a the effects of managerial efficiency on the firm s innovative activity and b the effects of controlling explicitly for managerial efficiency on the schumpeterian like relationship that firm size and market concentration are both conducive to innovation the key findings are managerial efficiency is an important determinant of the firm s innovation performance only when one controls for managerial variables considered as success factors for innovation the schumpeterian effect of the impact of the firm s market share emerges for a wide range of measures of performance which confirms rothwell s suggestion 18 that small firms have a advantage in the management of their innovation

flexibility choices and oligopolistic competition in an evolutionary environment we study the problem of the endogenous choice of technology when the level of demand is uncertain firms can choose either a flexible technology which allows them to vary the cost structure or a rigid technology which in periods of high demand is more efficient firms tend to adopt the ex ante more rewarding technology we develop a full dynamic model with given number of firms as well as with entry and exit and with perfect foresight as well as with myopic firms we show that firms with different technologies can coexist in the market in a permanent way and characterise the parameter configurations leading to such results

dynamic capacity management with general upgrading this paper studies a capacity management problem with upgrading a firm needs to procure multiple classes of capacities and then allocate the capacities to satisfy multiple classes of customers that arrive over time a general upgrading rule is considered i e unmet demand can be satisfied using multistep upgrade no replenishment is allowed and the firm has to make the allocation decisions without observing future demand we first characterize the structure of the optimal allocation policy which consists of parallel allocation and then sequential rationing specifically the firm first uses capacity to satisfy the same class demand as much as possible then considers possible upgrading decisions in a sequential manner we also propose a heuristic based on certainty equivalence control to solve the problem numerical analysis shows that the heuristic is fast and delivers close to optimal profit for the firm finally we conduct extensive numerical studies to derive insights into the problem it is foun

inefficient diversification in multi market oligopoly with diseconomies of scope this paper considers the incentives of oligopolistic firms to diversify into technologically related markets when there are diseconomies of scope there is a rent extraction incentive for firms to adopt flexible technologies which enable them to enter technologically related markets thereby increasing competition however this strategic motive leads to inefficiency in production owing to diseconomies of scope this paper shows that the welfare gain arising from increased competition is offset by the inefficiency in production which may lead to lower welfare than in the case of pure monopoly this is a counter example to the contention that the diversification increases social welfare

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

strategic commitment versus postponement in a two tier supply chain abstract in this paper the trade off between strategic commitment and operational flexibility is examined as it arises in a supply chain when a supplier offers competing buyers opportunities to make early purchase commitments for a product with a short life cycle traditionally the use of incentives for early purchase commitments for short life cycle products has been justified on the basis of a supplier s production lead times or capacity constraints an alternative explanation has been proposed by offering early purchasing opportunities a supplier can influence the form of competition in the downstream market using a single period model it has been shown that below a threshold level of demand uncertainty the supplier can benefit from providing adequate pricing incentives to entice downstream buyers to commit to purchase quantities before demand information is revealed moreover such early purchasing opportunities can benefit the supplier as well as the buyers even in the absence of production lead times or capacity constraints

economic analysis of social security survivors insurance this paper develops a heterogeneous agents model to analyze the effects of social security survivors insurance the model features a negative mortality income gradient asymmetric information of individual mortality rates and a warm glow bequest motive that varies by age and family structure the model matches lifecycle changes in life insurance coverage and generates advantageous selection in the insurance market for male agents reducing survivors benefits for dependent children generates welfare losses while reducing survivors benefits for aged spouses produces welfare gains the opposing welfare results are explained by differences in the timing of benefits and in the funding cost

economics of efficiency measurement by the dea approach three aspects of efficiency measurement by data envelopment analysis are discussed here analytically these aspects comprise output specific input allocations by each firm flexibility in the production process and the role of learning by doing in efficiency improvement

positive prices in capm some equilibrium prices in capm may be negative because of nonmonotonicity of preferences we identify several sets of sufficient conditions for prices to be positive the central conditions impose bounds on the investors risk aversion these bounds do not need to hold globally but only in a relevant range of portfolios or combinations of mean and standard deviation the relevant range is specified on the basis of exogenous parameters and variables and it must contain any endogenously determined equilibrium the bounds on risk aversion ensure that the preferences for assets are sufficiently well behaved within the relevant range the two period mean variance capital asset pricing model capm has the peculiar property that preferences may not be monotone the expected return to an investor s portfolio increases as he holds more and more shares of the assets but so does the variance of return it may be that at some point the additional expected return gained from adding more shares to the portfolio is not sufficient to compensate for the increase in variance if so then the induced preferences for assets are not monotone nonmonotonicity of preferences in the mean variance model is analyzed in nielsen 1987 because portfolio preferences are not necessarily monotone equilibrium asset prices may be negative or zero in fact it is possible that the value of the market portfolio of risky assets is negative this is demonstrated in nielsen 1985 1990a and in two examples in the present paper when the capm is used as a model of the prices of stocks which in reality have limited liability it is of course disturbing that it may predict negative prices it can be seen as a symptom of the fact that mean variance preferences are not always a good approximation to reality this paper analyzes various conditions on the exogenous parameters which ensure that the preferences are sufficiently realistic to yield positive prices the exogenous parameters in question are the expectations variances and covariances of total returns the initial allocations of the assets endowments and the investors utility functions for mean and variance of return the analysis applies to the classical version of the capm with a riskless asset as developed by sharpe 1964 lintner 1965 and mossin 1966 as well as the capm with risky assets only which was introduced by black 1972 and has been much used in empirical work under the name the zero beta or two factor capm

investments in flexible production capacity abstract we examine the technology and capacity choice problem of a multi output firm facing stochastic demands in a continuous time framework the firm can install output specific capital or at greater cost flexible capital that can be used to produce different outputs investment is irreversible the firm must choose a technology and decide how much capital to install knowing it can add more later as demand evolves we formulate the capacity choice problem as a singular stochastic control problem show that the value of the firm equals the value of its installed capital plus the value of its options to add capacity in the future and derive an optimal investment rule that maximizes the firm s market value we also address the analogous problem for a multi input firm that faces stochastically evolving factor costs and can install input specific or flexible capital

technological competition uncertainty and oligopoly abstract in an oligopoly context the present technological choice of a firm which expects to receive private revelant information just prior to the uncertain market stage has both a flexibility value and a strategic commitment value in contrast to some common wisdom ideas we provide a natural two stage competition framework in which an increase in uncertainty always raises the commitment value of the technological choice of the firm and may decrease its flexibility value when the increased uncertainty takes the form of more variable beliefs the first result tends to reinforce therefore the findings of the strategic commitment literature under certainty

the effect of succession taxes on family firm investment evidence from a natural experiment this paper provides causal evidence on the impact of succession taxes on firm investment decisions and transfer of control using a 2002 policy change in greece that substantially reduced the tax on intrafamily transfers of businesses i show that succession taxes lead to a more than 40 decline in investment around family successions slow sales growth and a depletion of cash reserves furthermore succession taxes strongly affect the decision to sell or retain the firm within the family i conclude by discussing implications of my findings for firms in the united states and europe

new evidence on the money s worth of individual annuities this paper presents new information on the expected present discounted value of payouts on individual life annuities the annuity we examine is the single premium immediate life annuity an insurance product that pays out a nominal level sum as long as the covered person lives in exchange for an initial lump sum premium this annuity offers protection against the risk of someone outliving his saving given uncertainty about longevity for reasonable estimates of behavioral parameters we calculate that individual annuities are currently priced so that retirees without bequest motives should find these policies of substantial value in configuring their portfolios to smooth retirement consumption we also find that the expected present discounted value of payouts relative to the initial cost of the annuity has increased over the last decade these findings bear on the policy debate regarding the role of individual choice and self reliance in retirement planning this abstract was borrowed from another version of this item

economic implications of 3d printing market structure models in light of additive manufacturing revisited abstract additive manufacturing am colloquially known as 3d printing is currently being promoted as the spark of a new industrial revolution the technology allows one to make customized products without incurring any cost penalties in manufacturing as neither tools nor molds are required moreover am enables the production of complex and integrated functional designs in a one step process thereby also potentially reducing the need for assembly work in this article we discuss the impact of am technology at both firm and industry level our intention is to discern how market structures will be affected from an operations management perspective based on an analysis of established economic models we first identify the economic and technological characteristics of am and distill four key principles relevant to manufacturers at firm level we then critically assess the effects of am at industry level by analyzing the validity of earlier assumptions in the models when these four principles apply in so doing we derive a set of seven propositions which provide impetus for future research in particular we propose that in a monopoly the adoption of am allows a firm to increase profits by capturing consumer surplus when flexibly producing customized products meanwhile in competitive markets competition is spurred as am may lower barriers to market entry and offers the ability to serve multiple markets at once this should ultimately result in lower prices for consumers

component commonality with service level requirements this paper extends recent results of baker et al baker k r m j magazine h l w nuttle 1986 the effect of commonality on safety stocks in a simple inventory model management sci 32 982 988 in understanding the impact of component commonality on stocking levels under service level constraints a model is formulated for an arbitrary number of products with general joint demand distribution the results obtained are not all intuitive while utilizing commonality is beneficial nothing general can be said about the resulting change in the components stock levels when the cost structure is of a particular simple form though some interesting general patterns do emerge we also discuss the case of using a service level measure where rationing of common components might be required and characterize the implied rationing rule

time to build option value and investment decisions abstract investment decisions and outlays are often made sequentially for example the rate at which construction proceeds is usually flexible and can be adjusted with the arrival of new information traditional discounted cash flow methods which treat the pattern of investment as fixed ignore this flexibility and understate the value of the project this paper uses contingent claims analysis to derive optimal decision rules and to value such investments we determine the effects of time to build opportunity cost and uncertainty on the investment decision for reasonable parameter values we show how a simple npv rule can lead to gross errors

prices vs quantities technology choice uncertainty and welfare technological improvements have proven essential in mitigating environmental problems such as climate change depletion of the ozone layer and acid rain while it is well known that price and quantity based regulatory instruments provide different investment levels the effects on the choice between different technologies have received scant attention this paper expands on the prices versus quantities literature by investigating firms technology choice in the face of demand and supply side uncertainty i show that the regulator can not design tradable emissions permits and an emissions tax such that the two regimes are equivalent even in terms of expected values moreover a tax encourages the most flexible abatement technology if and only if stochastic costs and the equilibrium permit price have sufficiently strong positive covariance compared with the variance in consumer demand for the good produced finally the firms technology choices are socially optimal under tradable emissions permits but not under an emissions tax

strategic choice of flexible production technologies and welfare implications this paper examines the market conditions under which firms would choose a more flexible production technology with respect to product design the authors use a two stage game in which firms choose between flexible and less flexible production technologies in the first stage and subsequently choose output they find that consumers would benefit from the introductions of flexible production technologies in their model the authors also find that the production technology game is a prisoner s dilemma when firms invest in flexible manufacturing systems they derive the conditions under which the resulting equilibria are efficient copyright 1990 by blackwell publishing ltd

technology investment under flexible capacity strategy with demand uncertainty abstract this paper investigates technology investment under flexible capacity strategy with demand uncertainty technology investment enables a firm to reduce its total production cost while flexible capacity strategy aims to reduce a firm s production waste by postponing production until demand is known adopting a general technology investment cost we examine how technology investment cost structure affects a firm s technology investment decisions we derive the conditions under which the firm will benefit from technology investment we show that the firm can increase its expected profit through technology investment only when the unit technology investment cost that varies inversely with the basic technology level is below a threshold however even though the technology investment cost is zero the benefit from the increase in technology level is limited furthermore we analytically determine the optimal technology levels and establish their relationships under different technology investment cost structures our findings will help firms evaluate various technology investment options and choose the most proper one
