the control of technology alliances an empirical analysis of the biotechnology industry we examine the determinants of control rights in biotechnology alliances through three case studies and a quantitative analysis aghion and tirole 1994 argue that control rights will be assigned so as to maximize the value of the final output as long as the r d firm has sufficient financial resources consistent with this framework the allocation of control rights to the r d firm increases with the firm s financial resources the empirical evidence regarding the relationship between control rights and the stage of the project at the time the alliance is signed is more ambiguous

creative destruction and productive preemptive acquisitions we develop a model of entrepreneurial innovation for entry and sale into oligopolies suitable for welfare analysis we show that the expected consumer welfare can be higher under commercialization by sale than under commercialization by entry despite increased market power in the product market the reason is that when the quality of the invention is sufficiently high preemptive bidding competition among incumbents drives the acquisition price above the entry value entrepreneurs who sell their inventions will then have a stronger incentive to develop high quality inventions than entrepreneurs who aim at entering the product market incumbents are hurt by this creative destruction process ignited by the entrepreneurs and thus have an incentive to undertake research to block entrepreneurs research activities we show that incumbents own research effort can reduce but not eliminate the entrepreneurs incentives to innovate for entry or sale

multidimensional mechanism design for auctions with externalities abstract in an auction with externalities a buyer s type is multidimensional and specifies the payoff he would get for each of the n 1 possible outcomes the seller keeps the object or buyer i i 1 n gets the object we provide a characterization of multidimensional incentive compatible mechanisms similar to that for one dimensional mechanisms although reservation utilities are endogenous and type dependent the participation constraint is binding for only one critical type a main difficulty in a multidimensional setting is the integrability condition we present a geometric characterization for discontinuous conservative vector fields in auctions where the buyers submit scalar bids and the seller transfers the object to one of the buyers for sure a second price auction maximizes revenue with two buyers this auction remains optimal even if the seller can set a reservation price journal of economic literature classification numbers c7 c72

how not to sell nuclear weapons we consider situations where a sale affects the ensuing interaction between potential buyers these situations are modeled by assuming that an agent who does not acquire the object for sale incurs an identity dependent externality we construct a revenue maximizing auction for the seller we observe that 1 outside options and participation constraints are endogenous 2 the seller extracts surplus also from agents who do not obtain the auctioned object 3 the seller is better off by not selling at all while obtaining some payments if externalities are much larger than valuations

quality improvements and the incentive to leapfrog abstract in a model of an uncovered market of vertically differentiated products incentives of non identical duopolists to improve the technological maximum quality are analyzed it is assumed that initially firms offer products with different qualities and that the r d cost function changes exogenously this induces a reconsideration of firms quality decisions both firms have the same r d costs for improving the maximum quality quality changes within the existing quality range are assumed to incur only fixed adjustment costs it is shown that the firm which initially is in the low quality position always has a higher incentive to improve industry s quality than its rival if adjustments costs are sufficiently high persistence of dominance may occur for a low degree of initial differentiation low adjustment costs and r d cost functions with a high slope

the effects of foreign strategic investors on business models in china s commercial banks does ownership structure matter abstractintroducing foreign strategic investors fsis is a vital step in the ownership reforms of china s banking industry using china s data from 1995 to 2014 we employ propensity score matching and difference in differences approaches to investigate the effects of fsis on the business models of chinese banks including income structure and funding structure we find that fsis significantly influence income structure the bank s non interest income nii share significantly rises after introducing fsis the higher ownership shares of fsis are associated with the higher nii share and the nii share has been increased when fsis assign directors or senior managers to chinese banks we also report that the effects of fsis on income structure are weaker in state owned banks than those in other banks and ownership concentration weakens the links between fsis and income structure finally this article shows that fsis have no significant influence on funding structure these findings will be informative and

disruption costs learning by doing and technology adoption abstract we study technology adoption in a dynamic model of price competition adoption involves disruption costs and learning by doing because of disruption costs the adopting firm begins in a market disadvantage which may persist if its rival captures the customers that the adopting firm needs to learn the technology the prospect of future rents by the rival results in i a failure to adopt socially efficient technologies ii an equilibrium preference for technologies that are learned faster but have lower social value and iii more technologies being adopted if more firms enter the market

splitting up value a critical review of residual income theories this paper deals with the notion of residual income which may be defined as the surplus profit that residues after a capital charge opportunity cost has been covered while the origins of the notion trace back to the 19th century in depth theoretical investigations and widespread real life applications are relatively recent and concern an interdisciplinary field connecting management accounting corporate finance and financial mathematics peasnell 1981 1982 peccati 1987 1989 1991 stewart 1991 ohlson 1995 arnold and davies 2000 young and o byrne 2001 martin petty and rich 2003 this paper presents both a historical outline of its birth and development and an overview of the main recent contributions regarding capital budgeting decisions production and sales decisions implementation of optimal portfolios forecasts of asset prices and calculation of intrinsic values a most recent theory the systemic value added approach also named lost capital paradigm provides a dierent denition of residual income consistent with arbitrage theory en folded in keynes s 1936 notion of user cost and forerun by pressacco and stucchi 1997 the theory has been formally introduced in magni 2000a b c 2001a b 2003 where its properties are thoroughly investigated as well as its relations with the standard theory two different lost capital metrics have been considered for value based management purposes by drukarczyk and schueler 2000 and young and o byrne 2001 this work illustrates the main properties of the two theories and their relations and provides a minimal guide to construction of performance metrics in the two approaches

the appraisal of industrial investments a new method and a case study abstract a general method of investment projects evaluation proposed by the second author is outlined it consists in decomposing in period quotas myers adjusted present value the analysis of these quotas provides satisfactory insight into the profitability of the project per se and its profitability through an adequate funding policy a case from real life concerning a large scale industrial investment is briefly discussed and some advantages of the method are highlighted

does sticky information affect the locus of innovation evidence from the japanese convenience store industry abstract scholars have long discussed the locus of innovation and its determinants there is empirical evidence that innovations can be developed by those holding any of a number of functional relationships to them such as manufacturers users or materials suppliers past studies have considered two factors important in predicting the functional locus of innovation one is expected profit of a player involved in the innovation and the other is stickiness of innovation related information although some studies have shown empirically the link between an innovator s expected profits and the locus of innovation no research has yet been conducted to test the hypothesized relationship between stickiness of innovation related information and the locus of innovation in the study reported upon here i explore relationships between these two variables via a study of 24 innovations for the japanese convenience store industry my study shows empirically that stickiness of innovation related information does have the hypothesized relationship to the functional locus of innovation i discuss implications of these findings and some directions for future research

competition or predation consumer coordination strategic pricing and price floors in network markets although network effects can make predation more likely to succeed we find that the leading anti predation rules may lower or raise efficiency and consumer welfare in network markets we find that a the extensive debates about the correct measure of cost on which to base price floors are unlikely to be productive b the ordover willig rule that is widely thought to be correct in theory but difficult to apply in practice is in fact incorrect in theory and c efficient price floors would have to depend on consumer expectations and coordination processes that are unlikely to be observable in practice

a model of the evolution of duopoly does the asymmetry between firms tend to increase or decrease this paper is an attempt to identify some of the factors that affect the evolution of market structure in a model of dynamic competition between two firms the stochastic evolution of the state of competition depends on the respective effort rates of the firms the question is whether the current leader works harder than the laggard does the gap between firms tend to increase or decrease we show that several effects are at work the state tends to evolve in the direction where joint payoffs are greater since joint payoffs are related to joint product market profits less joint effort costs there are two classes of effect the joint profit effect and various joint cost effects the latter result in part from the pattern of profits and in part from endpoint effects that give relief from efforts asymptotic expansions illuminate these influences moreover we show by numerical simulation that there is another kind of joint cost effect the pattern of joint effort costs can influence the pattern of evolution of market structure and the evolution of the pattern of market structure can influence the pattern of efforts in a mutually self reinforcing manner in particular there may be equilibria in which this last effect means that the laggard works harder than the leader even though all the other effects work in favour of the leader

entry and competitive dynamics in the mobile telecommunications market abstract we propose an extension of the gans stern gans j s stern s 2003 the product market and the market for ideas commercialization strategies for technology entrepreneurs research policy 32 2 333 350 framework that includes entry by existing firms an incumbent firm possessing complementary assets and strong appropriability is in a formidable position teece d j 1986 profiting from technological innovation implications for integration collaboration licensing and public policy research policy 15 6 285 305 however a de alio entrant can leverage complementary assets to enter along a new technological trajectory and then develop appropriability we illustrate how several mobile telecommunications firms ericsson nokia and samsung pursued this strategy to catch up with the market leader motorola we also identify several shortcomings in motorola s approach it was too inward looking in developing technologies but ironically not inward looking enough in exploiting its most valuable patents

when do auctions ensure the welfare maximizing allocation of scarce inputs we determine when an unfettered auction will ensure the welfare maximizing allocation of a scarce input that enhances product quality and may reduce production costs a supplier values the input for this use value and for its foreclosure value because once the input is acquired it is unavailable to rivals an unfettered auction often ensures the welfare maximizing allocation of an input increment however it can fail to do so when the input would increase relatively rapidly the competitive position of a rival with a moderate competitive disadvantage bidder handicapping that ensures auctions generate welfare maximizing input allocations differ from standard handicapping policies

investment financing and the role of roa and wacc in value creation abstract evaluating an industrial opportunity often means to engage in financial modeling which results in estimation of a large amount of economic and accounting data which are then gathered in an economically rational framework the pro forma financial statements while the standard net present value npv condenses all the available pieces of information into a single metric we make full use of the crucial information supplied in the pro forma financial statements and give a more detailed account of how economic value is created in particular we construct a general model allowing for varying interest rates which decomposes the project into investment side and financing side and quantifies the value created by either side an equity debt decomposition is also accomplished which enables to appreciate the role of debt in adding or subtracting value to equityholders further the major role of accounting rates of return as value drivers is highlighted and new relative measures of worth are introduced the project roa and the project wacc which aggregate information deriving from the period rates of return to achieve these results we make use of the average internal rate of return airr approach recently introduced which rests on capital weighted arithmetic means and sets a direct relation between holding period rates and npv

financial management in inventory problems risk averse vs risk neutral policies abstract in this work we discuss the effect of risk measure selection in the determination of inventory policies we consider an inventory system characterized by the loss function of luciano et al 2003 var as a risk measure for multi period static inventory models international journal of production economics 81 82 375 384 we derive the optimization problems faced by risk neutral quadratic utility mean absolute and cvar decision makers results show that while the global nature of the optimal policy is assured for risk coherent and risk neutral decision makers the convexity of the quadratic utility problem depends on the stochastic properties of demand we investigate the economic and stochastic determinants of the different policies this allows us to establish the conditions under which each type of decision maker is indifferent to imprecision in the distribution families finally we discuss the numerical impact of the choice of the risk measure by means of a multi item inventory the introduction of an approach based on savage scores allows us to offer a quantitative measurement of the similarity discrepancy of policies reflecting different risk attitudes

when do stronger patents increase continual innovation under continual innovation greater patent strength expands innovating firms profit against imitation but also shifts profit from current to past innovators we show how the impact of patents on innovation as determined by these two opposing effects varies with industry characteristics when the discount factor is sufficiently high the negative profit division effect is negligible and innovation monotonically increases in patent strength otherwise innovation has an inverted u relationship with patent strength and stronger patents are more likely to increase innovation when the discount factor or the fixed innovation cost is higher we also show how the impact of patents on innovation may change with firms innovation capability and with the intensity of competition from imitators

choosing the competition and patent licensing this article examines licensing as a means of choosing the competitors which a patentee monopolist will face in the period after the patent expires the queue of entrants consists of two firms which differ in their relative strengths as competitors for example by size or level of marginal cost by structuring the industry to be composed of weak competitors the incumbent is able to prolong its dominant position in the industry after the patent expires examples are presented in which the evidence suggests that choosing the competition was an important motivation of the licensor s behavior

does deposit insurance increase banking system stability an empirical investigation based on evidence of 61 countries in 1980 97 the authors find that explicit deposit insurance tends to be detrimental to bank stability the more so where bank interest rates are deregulated and the institutional environment is weak the adverse impact of deposit insurance on bank stability tends to be stronger the more extensive is the coverage offered to depositors and where the scheme is funded and run by the government rather than the private sector

innovation and the persistence of monopoly abstract the auction framework enables us to highlight a crucial feature of many r d races the losing firm can recoup part but not the entirety of its r d investments this feature is shown to account for the marked differences in results obtained by gilbert and newbery and by reinganum when the firm investing the largest amount wins with certainty we establish the existence of a unique equilibrium neither firm employs a pure strategy and the incumbent wins more often than the challenger

is it a car or a truck managerial beliefs the choice of product architecture and the emergence of the minivan market segment new markets segments are a common setting for studies in technology strategy these studies generally assume that new segments already exist or have formed following the introduction of a product innovation by an entering firm thus theory on the role of established firms in the emergence of new market segments is underdeveloped this study informs current research by explaining the product innovation decisions of established firms during the emergence of a new market segment the results of a case study on the development and commercialization of the minivan at chrysler ford and general motors between 1970 and 1985 indicate that existing theories based on managerial cognition firm capabilities economic incentives and organizational structure are insufficient to explain the decisions this article develops theory based on the interrelationship of these four mechanisms

revisiting foundations in lot sizing connections between harris crowther monahan and clark abstract while many review articles exist on deterministic lot sizing models used in the context of price and quantity discounts buyer vendor coordination supply chain management and joint economic lot sizing problems they do not convey the impact of important findings which date back to at least 2002 or in hindsight to 1984 as a result many recent articles still model the financial implications of lot sizing decisions without having the assurance that these models would help the firm s involved in maximising the net present value npv this paper therefore reviews these findings while adding also its own contributions as to convey the general importance to lot sizing theory we show that the underlying principles used in the four key articles that have led to a division in modelling approaches are in fact all in line with npv and argue that therefore there should not be these discrepancies that currently persist in the literature we establish the connections between these four strands of the literature using the solution to a simple variation of harris eoq model deriving thereby results from boyaci and gallego 2002 and beullens and janssens 2011 but showing their general applicability to any type of supply chain structure the breath of implications to deterministic lot sizing theory is illustrated using practical examples we present a stochastic version of the model of crowther 1964 which is arguably the least understood and applied model but on the other hand the most important one in realising how these modelling strands can be unified

dynamic inducements in r d investment market signals and network locations this research shows that alliance networks shape how firms respond to uncertainty reducing information generated outside a network product awards signal the potential commercial success of the awa

global sensitivity analysis in inventory management abstract this paper deals with the sensitivity analysis sa of inventory management models when uncertainty in the input parameters is given full consideration we make use of sobol function and variance decomposition method for determining the most influential parameters on the model output we first illustrate the method by means of an analytical example we provide the expression of the global importance of demand holding costs order costs of the harris economic order quantity eoq formula we then present the global sa of the inventory management model developed by luciano and peccati 1999 capital structure and inventory management the temporary sale problem international journal of production economics 59 169 178 for the economic order quantity estimation in the context of the temporary sale problem we show that by performing global sa in parallel to the modeling process an analyst derives insights not only on the eoq structure when its expression is not analytically known but also on the relevance of modeling choices as the inclusion of financing policies and special orders

deposit insurance bank exit and spillover effects abstract this study resolves a puzzle in the banking literature why do an increasing number of countries adopt a deposit insurance scheme dis while prior studies have shown that it increases the likelihood of banking crises using a dataset of 64 countries over the period 1970 2009 our study shows that the adoption of a dis is associated with a 2 0 4 7 percentage points higher likelihood of banking crises the direct effect while it is associated with a 10 1 11 1 percentage points lower likelihood of non banking financial crises the spillover effect since the spillover effect is larger than the direct effect a dis actually increases overall financial stability additionally we analyze the mechanisms through which a dis affects financial crises first we highlight the existence of the implicit guarantee and examine its interaction with an explicit dis second we investigate the substitution effect between banking crises and non banking crises

an inventory control model with stochastic review interval and special sale offer abstract periodic review inventory models are widely used in practice especially for inventory systems in which many different items are purchased from the same supplier however most of periodic review models have assumed a fixed length of the review periods in practice it is possible that the review periods are of a random stochastic length this paper presents an inventory control model in the case of random review intervals and special sale offer from the supplier the replenishment interval is assumed to obey from two different distributions namely exponential and uniform distributions also shortages are allowed in the term of partial backordering for this model its convexity condition is discussed and closed form solutions are proposed

aggregate return on investment for investments under uncertainty abstract this paper deals with capital budgeting decisions under uncertainty we present an aggregate return on investment aroi obtained as the ratio of total undiscounted cash flow to total invested capital and show that it is a genuine rate of return which compared with the risk adjusted cost of capital correctly signals wealth creation for choosing between two mutually exclusive projects we derive an incremental aroi and an incremental risk adjusted cost of capital by means of which two unequal risk projects can be correctly compared iterating the incremental procedure we show that the aroi approach correctly ranks any bundle of different risk competing projects relations with other criteria such as modified internal rate of return average irr cash multiple and profitability index are provided theoretically the aroi approach constitutes a link between arbitrage choice theory and corporate investment theory and shows that explicit discounting is not necessary for measuring economic profitability practically the aroi is a user friendly easy to compute rate of return derived from the same set of data required by the net present value npv also it does not incur the difficulties met by the internal rate of return irr in particular it is unique and it is based on economically significant capital values i e market driven values as such the aroi significantly expresses the efficiency of the project s invested capital

bank reforms foreign ownership and financial stability abstract numerous studies have focused on foreign ownership of banks but instead of linkages to financial stability they typically analyzed other issues and used country level data this article fills the gap in the literature by applying the gmm techniques on dynamic panels using bank level data for asian countries to investigate the impact of foreign ownership on financial stability as well as whether the relation between foreign ownership and stability changes under different conditions of bank reforms in the host country specifically we reach five conclusions first the existence of the home field advantage hypothesis is supported nevertheless when considering the effects of bank reforms the global advantage hypothesis holds second an inverse u shaped relation between foreign ownership and stability is supported third a higher degree of credit control liberalization mitigates the negative effect of foreign ownership on stability fourth liberalization of interest rate control and banking supervision do enhance stability fifth and finally we confirm a significantly negative relation between an explicit deposit and stability

persistence of innovation in dutch manufacturing is it spurious this paper studies the persistence of innovation and the dynamics of innovation output in dutch manufacturing using firm data from three waves of the community innovation surveys cis pertaining to the periods 1994 1996 1996 1998 and 1998 2000 we estimate by maximum likelihood a dynamic panel data type 2 tobit model accounting for individual effects and handling the initial conditions problem we find that there is no evidence of true persistence in achieving technological product or process innovations while past shares of innovative sales condition albeit to a small extent current shares of innovative sales

deposit insurance coverage ownership and banks risk taking in emerging markets abstract we ask how deposit insurance systems and ownership of banks affect the degree of market discipline on banks risk taking market discipline is determined by the extent of explicit deposit insurance as well as by the credibility of non insurance of groups of depositors and other creditors furthermore market discipline depends on the ownership structure of banks and the responsiveness of bank managers to market incentives an expected u shaped relationship between explicit deposit insurance coverage and banks risk taking is influenced by country specific institutional factors including bank ownership we analyze specifically how government ownership foreign ownership and shareholder rights affect the disciplinary effect of partial deposit insurance systems in a cross section analysis of industrial and emerging market economies as well as in emerging markets alone the coverage that maximizes market discipline depends on country specific characteristics of bank governance this risk minimizing deposit insurance coverage is compared to the actual coverage in a group of countries in emerging markets in eastern europe and asia

regulation innovation and the introduction of new telecommunications services i examine the effects of fcc regulation on the innovation and introduction of advanced telecommunications services in the united states an interim of lighter regulation provides an experiment to test the regulatory regime s impact the econometric model comprises an arrival process for service innovation followed by a duration process for regulatory delay the number of services the firms created during the interim is 60 99 higher than the model predicts they would have created if the stricter regulation had still been in place overall firms would have introduced 62 more services to consumers during the study period if the regulation had not been in place

evaluation of capital costs in a multi level inventory system by means of the annuity stream principle abstract in this paper some results obtained from applying the annuity stream principle for evaluating capital tied up in inventory and work in progress and presented this principle departs from the cashflows associated with the production inventory processes considered in contrast to traditional procedures by which the inventory value is determined from physical stock evaluated at costs incurred to date in many situations it appears that the traditional procedure will underestimate the amount of capital tied up in production in this paper the two principles are applied to a multi level inventory system and the capital cost expressions and optimal order quantities are compared

the discounted r q inventory model the shrewd accountant s heuristic abstract the discounted continuous review r q inventory model with continuous and stochastic demand is investigated new optimality conditions are derived clarifying the difference to the average cost case also graphically supported by depreciation theory applied to the value of a setup the results suggest an insightful and very precise approximation the shrewd accountant s heuristic based on a new average cost model it deepens and extends the work of hadley 1964 three examples are worked out in detail and the model is generalized to poisson demand and to stochastic lead times

resale markets and the assignment of property rights the consumption of an indivisible good causes identity dependent externalities to non consumers we analyse resale markets where the current owner designs the trading procedure but cannot commit to future actions we ask the following questions 1 doer the identity of the initial owner matter for the determination of the final consumer 2 is the outcome always efficient the major conclusion of our paper is that the irrelevance of the initial structure of property rights arises in resale processes even if there are transaction costs that hinder efficiency this result complements the coasian view where the irrelevance of the assignment of property rights is a consequence of efficiency

a new pragmatic approach to capital investment appraisal the financial appraisal profile fap model abstract evidence is produced to support the claim that management have not fully accepted the advice of academics in the use of sophisticated capital investment appraisal methods with managers continuing to use the non dcf methods alongside the irr and npv the concern that some managers may even abandon formal financial and project risk assessment altogether has lead to the development of a new profile approach the financial appraisal profile fap model is described in detail and illustrated through the use of an illustrative case study

invention and innovation under alternative market structures the case of natural resources this paper examines the interactions between market structure and resource allocation over time when there is endogenous technical progress the structures considered are a planned economy pure monopoly and competition with patent rights in an efficient allocation the date of invention coincides with the date of innovation the date at which technology is used this is also true with a pure monopoly but monopoly retards technical progress relative to the efficient level competition for patents rights to a new technology results in excessively rapid technical progress if the resource endowment of the economy is sufficiently large also competition may lead to sleeping patents where invention strictly precedes the date of innovation

average rates of return working capital and npv consistency in project appraisal a sensitivity analysis approach abstract in project appraisal under uncertainty the economic reliability of a measure of financial efficiency such as a rate of return depends on its strong npv consistency meaning that the performance metric i supplies the same recommendation in accept reject decisions as the npv ii ranks competing projects in the same way as the npv iii has the same sensitivity to perturbations in the input data as the npv in real life projects financial efficiency is greatly affected by the management of the working capital using a sensitivity analysis approach and taking into explicit account the role of working capital we show that the average return on investment roi is not strongly npv consistent in accept reject decisions if the working capital is uncertain and changes under changes in revenues and costs also it is not strongly npv consistent in project ranking we also show that the internal rate of return irr is not strongly npv consistent and economic analysis may even turn out to be impossible owing to possible nonexistence and multiplicity caused by perturbations in the input data as well as to possible shifts in the financial meaning of irr under changes in the project s value drivers we introduce the straight line rate of return slrr based on the notion of average rate of change which overcomes all the problems encountered by average roi and irr it always exists is unique strongly npv consistent for both accept reject decisions and project ranking and has an unambiguous financial nature

price cap regulation and technical change abstract existing analyses of the implications of price cap regulation for the development of cost reducing technologies assume that all r d is done by the regulated industry this is unrealistic we present a simple model of non cooperative r d by a regulated firm and a single external developer under a price cap regime of the sort characterised by cabral and riordan in equilibrium the external developer exerts less r d than is socially optimal the regulated firm may exert more or less a tightening of the regulatory regime impacts the r d incentives of both players though in different ways the optimal regulatory adjustment parameter may be bigger or smaller than that suggested by existing studies despite the scope for duplication of results research by an outsider necessarily enhances welfare

differential importance and comparative statics an application to inventory management abstract in this work we deal with the problem of establishing which parameters impact an inventory policy the most a new sensitivity measure is introduced by relating the differential importance d and the comparative statics cs techniques we discuss the properties of the new indicator and show that it shares the additivity property we provide the expression of for optimization models numerical results are offered for the sensitivity analysis of a recently introduced inventory management model

the importance of assumptions in investment evaluation abstract this work illustrates a new method for estimating the importance of assumptions in investment evaluation the most diffused sensitivity analysis schemes present limitations when used to assess the importance of individual parameters and cannot be employed to estimate the importance of groups of assumptions however such problems can be solved by making use of the differential importance measure dim we set forth the framework for the application of dim at the parameter level of investment valuation models we study the relationship between dim and investment marginal behavior we analyze the link between importance of a parameter and risk associated with it we discuss general results for a sample valuation model the numerical application to the valuation of an energy sector investment project follows we rank the factors based on their importance and determine the project risk profile we discuss the importance of groups of assumptions results will show that assumptions relating to revenues are the most influential ones followed by discounting and operating cost assumptions we discuss numerically the relationship between importance and risk analyzing the effect of variable costs hedging through the comparison of the project risk profile in the presence and in the absence of such a hedging

strategic behaviour of incumbent firms in the uk abstract the main purpose of this paper is to examine the incidence of strategic behaviour in the uk by means of a questionnaire study performed across three broad manufacturing industries food electrical engineering and chemicals of the strategies which have received substantial theoretical attention r d and advertising appear widely used patenting pricing and excess capacity much less so vertical instruments such as purchasing policy also stand out as important but possibly only a minority of firms in our sample actively pursue strategic instruments

an economic order quantity model with partial backordering and a special sale price abstract a constant unit purchase cost is one of the main assumptions in the classic economic order quantity model in practice suppliers sometimes offer special sale prices to stimulate sales or decrease inventories of certain items in this paper we develop an eoq model with a special sale price and partial backordering we prove the convexity of the cost reduction function if a special order is placed at the special sale price a solution method is proposed and numerical examples are presented

an eoq model for perishable product with special sale and shortage abstract in this paper for the first time an inventory control model to determine the optimal order and shortage quantities of a perishable item when the supplier offers a special sale is developed four possible cases based on decision that the purchaser might make about the first replenishment policy using regular economic order quantity model at reduced price or regular price if he did not take the special order and coincidence of special period length with positive or negative inventory level of the last regular period length during the special period are investigated moreover several useful theorems are suggested through which one can find closed form solution directly when there are integer operators involved in an objective function at the end in order to illustrate the proposed theorems and the solution method some numerical examples are solved and a sensitivity analysis is reported too

preemptive patenting and the persistence of monopoly this article takes a different tack and inquires whether institutions such as the patent system create opportunities for firms with monopoly power to maintain their monopoly power the results apply to other situations such as brand identification spatial location and capacity expansion which share the characteristic that early or preemptive actions may lower the returns to potential competitors

ordering and inventory policies for step changes in the unit item cost a discounted cash flow approach this paper considers the problem of determining the optimal ordering quantities of a purchased item where there are step changes in price either up or down other costs incurred include ordering costs associated with each replenishment and holding costs related to capital tied up in inventory and physical stock holding the net present value npv principle is applied explicit expressions for the development of the optimal order quantities over time are presented it is shown that three cases may be distinguished i when the price change is very small ii when an essential price increase occurs and iii when there is an essential price decrease although the optimal last order quantity before a price increase is similar in magnitude to what has been presented in other articles applying average cost approaches in certain respects this paper offers novel results contradictory to those suggested by other authors analysis shows that the average cost model solutions are first order approximations in the discount rate numerical evaluations of a range of price increases and times to the price increase suggest that with certain important caveats the average cost formulae are likely to be acceptable for most practical situations for the infinite horizon situation

differences in the rates of return to r d for european and us young leading r d firms this paper examines the sources of europe s lagging business r d performance relative to the us particularly the role played by missing young leading innovators in high technology intensive sectors in europe it investigates through econometric analysis differences in the rates of return to r d of european and us large r d firms it finds that while in the us young firms succeed in realizing significantly higher rates of return to r d as compared to their older counterparts including in high tech sectors european firms fail to generate significant rates of return even if they are yollies and even if they are in high tech sectors these findings can at least partly explain why europe has less r d intensive young leading innovators in high technology intensive sectors

note comments on the optimality in optimal and system myopic policies for multi echelon production inventory assembly systems schwarz and schrage s model assumes that for optimal policies in a multi echelon production inventory system the lot size of a stage must not be larger than that of a predecessor stage as lots move from the initial stage to the final stage examples in this note illustrate that set up costs and inventory holding costs may be such that optimal inventory policies exist when smaller lot sizes are produced intermittently at a stage with an overlap to feed the continuous production of a larger lot size at the next stage also an example shows that in contrast with another assumption in their model optimality does not always require that the lot size at each stage be an integer multiple of the lot size at the successor stage

holding costs under push or pull conditions the impact of the anchor point holding costs are traditionally determined from the investment in physical stock during a cycle an alternative approach instead derives holding costs from net present value npv functions it is known that applying both frameworks to the same system can lead to different holding cost valuations but little explanation has been offered by introducing the anchor point in a model this paper shows for four different systems that traditional holding cost models implicitly assume pull conditions while current npv approaches model push conditions this explains in part the differences between the methods it is shown that the anchor point concept allows the construction of npv models under pull conditions giving results in better correspondence with traditional models the traditional framework is restricted to pull conditions and important considerations could be easily overlooked leading to wrong valuations of holding costs npv seems superior as such considerations are automatically incorporated the application to multi echelon inventory systems provides interesting insights on the roles of echelon stocks and lead times and offers potential for future research

how to license intangible property we examine the optimal licensing strategy of a research lab selling to firms who are product market competitors we consider an independent lab as well as a research joint venture we show that 1 demands are interdependent and hence the standard price mechanism is not the profit maximizing licensing strategy 2 the seller s incentives to develop the innovation may be excessive 3 the seller s incentives to disseminate the innovation typically are too low 4 larger ventures are less likely to develop the innovation and more likely to restrict its dissemination in those cases where development occurs and 5 a downstream firm that is not a member of the research venture is worse off as a result of the innovation

production experiences and market structure in r d competition abstract in the rd and ii the likelihood of persistent leadership increases with the value of being the winner and the value of being a loser but decreases with expected waiting time of r d innovation and the flow of monopoly profits however destructive innovations may still occur even when production experiences are allowed to play an important role in the r d competition

cycles optimization the equivalent annuity and the npv approaches abstract the paper discusses the use of a generalized version of the equivalent annuity principle which takes into account interest rate fluctuations over time when dealing with applications over a sequence of cycles e g plant replacement ones the equivalent annuity is usually defined with reference to each single cycle or to the whole sequence first we study the correspondence between net present values and equivalent annuities as defined above in optimization problems we show that only the second definition is appropriate for optimization whenever the length of the cycle is a choice variable however also the second is not necessarily correct when the horizon is finite then we discuss the corresponding problems of optimality both with an infinite and a finite sequence of cycles applications to a simple plant replacement problem are illustrated they show how different the optimal decisions can be from the equivalent annuity ones

costing partial order cycles in the temporary sale price problem the selection of a special order quantity in response to a temporary price reduction is usually derived by comparing the benefits of a special order in terms of a lower purchase price with the additional holding cost if the offer is rejected the analysis is usually carried out over a finite planning horizon under various cost allocation specifications thus neglecting the longer term effects of these offers in contrasting the different solutions this paper shows i that the basic differences among the various earlier formulations centres around the evaluation of the cost of a partial inventory cycle within the average cost avc approach ii that the net present value npv approach eliminates the partial order cycle problem by evaluating cash flows always at the time of occurrence thus obviating the need for considering partial order cycles and iii that the various avc specifications presented in this paper yield excellent approximations to the theoretically correct but harder to use npv formulation numerical examples highlight the main features of the paper

the impact of international information disclosure requirements on market discipline abstractfinancial regulators are challenged with finding the most efficient and effective ways to monitor banks given an expanding and complex international financial system market discipline has grown in importance as a way to discourage banks from taking on unnecessary risk one of the main drivers of market discipline is information disclosure while the literature on market discipline is expansive there are no known studies on the impact of individual information disclosure requirements on market discipline our study investigates which specific disclosure requirements influence financial investors to discipline banks and which do not we find that information disclosure requirements primarily reduce or have no impact on market discipline practices

second mover advantages in the strategic adoption of new technology under uncertainty abstract this paper introduces technological uncertainty into a timing game of new technology adoption it is shown that the timing neither necessarily involves first mover advantages in precommitment equilibria reinganum review of economic studies xlviii 1981 395 405 nor rent equalization due to the threat of preemption fudenberg and tirole review of economic studies lii 1985 383 401 rather there may be second mover advantages because of informational spillovers furthermore the model predicts that the equilibrium payoffs will typically be discontinuous and non monotonic in the probability that the new technology is profitable a welfare analysis reveals several market failures and suggests that policy intervention should adequately depend on the nature of uncertainty and the rate of technological progress

monopoly incentives for cost reducing r d abstract it is shown in this paper that there exist cost innovations for which a monopolist has a higher incentive to invest than a social planner this unveils the limits of the claim based on arrow 1959 that a monopoly always has a lower incentive to innovate than a social planner and therefore than is socially desirable in contrast to previous results the comparison of incentives may also depend upon the demand function finally for a restricted domain of analysis a rule for comparing the monopoly and the social planner incentives is derived

and the winner is acquired entrepreneurship as a contest yielding radical innovations new entrants to a market tend to be superior to incumbents in originating radical innovations we provide a new explanation for this phenomenon based on markets for technology it applies in industries where successful entrepreneurial firms or their technologies are acquired by incumbents that then commercialize the innovation to this end we analyze an innovation game between one incumbent and a large number of entrants in the first stage firms compete to develop innovations of high quality they do so by choosing at equal cost the success probability of their rd the bigger the number of entrants the more radical the most radical project generally entrants tend to choose more radical r d approaches and generate the highest value innovation in case of success we illustrate our theoretical findings by a qualitative empirical study of the electronic design automation industry and derive implications for research and management

reformulating tax shield valuation a note standard financial theory in the absence of agency costs and personal taxes implies that each dollar of debt contributes to the value of the firm in proportion to the firm s tax rate to derive this result incremental debt is assumed permanent this paper shows that when the firm acts to maintain a constant market value leverage ratio the marginal value of debt financing is much lower than the corporate tax rate since hamada s 2 unlevering procedure for observed equity betas was derived under the assumption of permanent debt we derive an unlevering procedure consistent with the assumption of a constant leverage ratio implicit in the modigliani miller 4 hypothesis regarding the effect of leverage changes on firm value is that the firm maintains a constant level of debt the purpose of this paper is to examine the implications for tax shield valuation of maintaining a constant market value leverage ratio instead of a constant debt level assuming a constant leverage ratio instead of a constant debt level does not imply any change in the normative implications of capital structure theory however we show that when the firm s financing strategy is to maintain a constant market value leverage ratio the marginal value of a change in debt level resulting from a change in this leverage ratio is much lower than the corporate tax rate we also derive the relationship between the firm s equity beta and its unlevered beta under the assumption of a constant leverage ratio

analyzing literature based innovation output indicators the italian experience abstract this paper presents the results of a study on the product innovations introduced in the italian market in 1989 and reported in a selected number of trade journals the analysis of data collected by means of this literature based counting procedure confirms that r d oriented industries and large firms do not in italy have a marked competitive advantage in innovation the country appears to be instead characterized by a significant presence of consumer goods industries and small firms in innovation our data indicate a statistically significant association between trade competitiveness and strength in product innovation and show the comparatively higher capacity for product innovation of some of the industries in which italy achieves a positive performance in international trade moreover the presence of spillovers at the regional level from both private and public r d expenditures proves to be positively correlated with the development of product innovations finally small firms with fewer than 50 employees appear to be more innovative than is usually believed to be the case

some basic problems in inventory theory the financial perspective the analysis of the standard eoq problem from a financial perspective is proposed the case of mixed financing equity and debt is considered and the results are compared with those stemming from the average cost approach it is shown that no prediction about the result can be made we solve completely the problem of finding the best financing policy as the financial framework suggests to consider an infinity of inventory cycles we investigate the effects on the solution of a more realistic finite truncation of the chain we show that the finite chain solution is always smaller than the infinite chain one

intellectual property rights and the mode of technology transfer abstract transferring technology in an environment where patent protection is uncertain can pose significant risks to an innovating firm s ability to appropriate rents this paper incorporates asymmetric information in a screening game where the innovating firm has the choices of licensing a new product at arm s length to a foreign firm exporting it or licensing it to a subsidiary subsidiary production avoids the risk of imitation but involves higher costs for the innovating firm the gains to the southern country from the lack of intellectual property right protection may be offset by strategic behavior by northern firms who opt for technology transfer via subsidiary or monopoly production

ownership structure market discipline and banks risk taking incentives under deposit insurance the paper studies the effects of market discipline by creditors and ownership structure on banks risk taking in the presence of partial deposit insurance an agency cost model explains how the effects of creditor discipline and shareholder control arc interdependent the non monotonic effect of shareholder control and the role of leverage panel regressions on several hundred banks worldwide 1995 2005 confirm a negative individual risk effect of creditor discipline and the expected convex effect of shareholder control increased shareholder control significantly strengthens the negative effect of market discipline on asset risk but joint effects on overall default risk are limited c 2011 elsevier b v all rights reserved

capital structure and inventory management the temporary sale price problem the paper discusses the use of adjusted present value techniques in a problem of inventory management the temporary sale price problem in the presence of equity or debt financing while traditional net present value approaches produce results very similar to those of the average cost approach our consideration of the capital structure of the firm opens the way to theoretically and numerically different inventory policies
