the management of multinational r d a neglected topic in international business research despite the growing involvement of multinational firms in foreign based r d during the past fifteen years little research has been done on why and how firms internationalize their r d and what effects it might have on firm competitiveness the present paper calls attention to this neglect and seeks to advance the management of multinational r d as an area of study for international business scholars to this end the paper first examines the key contributing factors to increased foreign r d investments among multinationals it then reviews the research literature to find out what we presently know about the management of multinational r d finally a research agenda is proposed to provide a foundation and stimulus for future investigations seven research directions are recommended with an emphasis on interdisciplinary inquiry and a focus on issues that have both theoretical and practical significance

bi level game approaches for coordination of generation and transmission expansion planning within a market environment the main purpose of this paper is to develop methodologies for simultaneous generation and transmission expansion planning problem of power networks while investigating interactions between these two important sections in the proposed methodologies a transmission operator to operating under different incentives decides about investment in transmission network while anticipating the outcome of a purely competitive electricity market where several rival generation firms complete with each other to determine operating level of their generators amount of their sales and amount of their investment in generation capacity the proposed methodologies rely on bi level programming models whose upper level model represent the problem of investment in transmission by to and the lower level problems represent market outcomes obtained from clearing the market these bi level models are reduced to mixed integer linear and nonlinear programming using the duality theory and karush kuhn tucker kkt optimality conditions the results of the proposed models are analyzed and compared using two illustrative examples

a three level static milp model for generation and transmission expansion planning we present a three level equilibrium model for the expansion of an electric network the lower level model represents the equilibrium of a pool based market the intermediate level represents the nash equilibrium in generation capacity expansion taking into account the outcomes on the spot market and the upper level model represents the anticipation of transmission expansion planning to the investment in generation capacity and the pool based market equilibrium the demand has been considered as exogenous and locational marginal prices are obtained as endogenous variables of the model the three level model is formulated as a mixed integer linear programming milp problem the model is applied to a realistic power system in chile to illustrate the methodology and proper conclusions are reached

impact of forecast errors on expansion planning of power systems with a renewables target abstract this paper analyzes the impact of production forecast errors on the expansion planning of a power system and investigates the influence of market design to facilitate the integration of renewable generation for this purpose we propose a programming modeling framework to determine the generation and transmission expansion plan that minimizes system wide investment and operating costs while ensuring a given share of renewable generation in the electricity supply unlike existing ones this framework includes both a day ahead and a balancing market so as to capture the impact of both production forecasts and the associated prediction errors within this framework we consider two paradigmatic market designs that essentially differ in whether the day ahead generation schedule and the subsequent balancing re dispatch are co optimized or not the main features and results of the model set ups are discussed using an illustrative four node example and a more realistic 24 node case study

financial repression and firm self financing of investment empirical evidence from brazil analysis of 86 brazilian manufacturing firms operating during a period marked by some degree of financial repression demonstrates that investment spending influences the liquid asset holdings of firms this self finance motive is weaker than the transactions motive but in general remains statistically significant across a variety of model specifications small firms are more likely than large firms to finance investment spending through accumulation of liquid assets contrary to the complementarity hypothesis however there is some evidence that firms treat liquid assets and capital as substitutes specification tests comparing the shaw hypothesis with the mckinnon hypothesis weakly favour the complementarity model

sequential coordination of transmission expansion planning with strategic generation investments this paper proposes mathematical models for sequential coordination of transmission expansion planning with strategic generation investments the proactive and reactive coordinations are modeled and studied the interaction between transmission company transco and strategic generation companies gencos is modeled using the sequential move game this is while the interaction between the strategic gencos is modeled as a simultaneous move game in the proactive coordination the transco expands its future transmission capacities taking into account the strategic investments by gencos in the reactive coordination strategic gencos move first and expand their future generation capacities and then transco expands the transmission capacity the proactive coordination is modeled as a mixed integer bilevel linear program miblp and the reactive coordination is modeled as a mixed integer linear program milp the miblp has binary variables in both upper and lower levels the moore bard algorithm is parallelized and used to solve the miblp the mathematical models and the parallelized moore bard algorithm are tested on 3 bus and 6 bus example systems and the modified ieee rts96 also the ieee 118 bus test system is studied using a heuristic version of the moore bard algorithm

a principal agent approach to transmission expansion part i regulatory framework different regulatory frameworks have implemented competitive mechanisms to increase efficiency in transmission a natural monopoly conflicts of interest and hidden costs make necessary to define methods to obtain an appropriate valuation of new transmission assets this paper is the first one of a two paper series and presents the fundamentals of transmission project valuation and cost allocation we show the fundamentals of non cooperative game theory different concepts of game equilibria nash stackelberg and berge and solutions to the bilateral negotiation problem nash bargaining solution kalai smorodinsky and rubinstein in addition the design of mechanisms the information revelation principles and incentive compatibility issues are described we propose a model composed of three elements valuation of a transmission project based on a linear contract a principal agent model to determine the optimal effort of an agent developing the transmission project and the optimal bilateral negotiation of right of way costs we define a method to evaluate the offers to build a transmission line project as a function of the number of agents bidding for it the value of the project is a function of both the incentives and the valuation of the right of way costs in part two of this series we present two case studies the ieee 24 bus rts and the sistema interconectado central sic in chile where we apply the methodology to a real network

financial liberalization in india and a new test of the complementarity hypothesis abstract this article reappraises the financial repression hypothesis for india in light of the partial liberalization of the financial sector in the early 1990s using for the first time state of the art multivariate cointegration and vector error correction models vecm from this more robust testing procedure we find that for the indian economy over the sample period 1951 99 money and capital are complementary suggesting that higher real interest rates will further raise the demand for money and lead to higher levels of investment furthermore testing for a structural break in the early 1990s to coincide with the liberalization of the financial sector in india suggests that these reforms have not significantly changed the complementary relationship between money and capital the policy implication is that further financial liberalization maybe required in india to enhance investment and economic growth

what is the value of the option to defer an investment in transmission expansion planning an estimation using real options abstract in deregulated markets transmission expansion planning tep is usually performed by a central network planner seeking to maximize social welfare in doing that the network planner commonly follows a traditional project valuation considering a discounted cash flow dcf methodology although incorporating uncertainty and reliability considerations accordingly once the optimal transmission expansion plan is determined the network planner frequently auctions the needed investments obligating the investor to execute the expansion in the fixed inflexible terms defined in the bidding process a key problem is that dcf does not take into account the responses of the planner when uncertainties are resolved because dcf evaluates the project with the information available today in tep managerial flexibility may be valuable because optimal decisions may change over time with the release of new information transmission investors may want to defer or expand according to such information the aim of this article is to estimate the value of adding some flexibility in tep through real options in particular by means of using a real option approach with binomial trees we study the benefits for a social network planner of having the option to defer some transmission investments our results suggest that incorporating flexibility in tep may increase social welfare

the relation between real cash balances and physical inputs in south korea s manufacturing sector abstract this study investigates the role of real cash balances and primary inputs in the production process of an average firm in a newly industrializing country south korea for 1968 1983 it is hypothesized that real balances and capital in the modern sector of industrializing countries are substitutes akin to those of the developed countries whereas in the traditional sector the two inputs are complements similar to those of the less developed countries using the translog cost function approach the hypothesis is verified for south korea the results also shed some light on the korean miracle of growth along with implications for income redistribution

global connectedness and local innovation in industrial clusters in today s knowledge economy clusters are a key driver of a country s competitiveness yet a cluster s technological base is now more than ever influenced by constituent firms actions to tap into distant knowledge sources drawing on a social network perspective and distinguishing between horizontal versus vertical organization based linkages we explore the effects of a cluster s connectedness to foreign locations on its innovation performance we show that improvements in horizontal and vertical connectedness both stimulate a cluster s innovation performance but that their relative effects vary across cluster types innovation in knowledge intensive clusters disproportionately benefits from enhancements in their constituent firms horizontal connectedness to foreign knowledge hotspots innovation in labor intensive clusters mostly gains from stronger vertical connections by their firms to central value chain players abroad we discuss the implications of our findings for research on global knowledge sourcing and cluster upgrading

the economic value of transmission lines and the implications for planning models abstract many connections between economic efficiency regulation the environment and energy markets are evident in the planning for transmission upgrades in an electricity network transmission owners have to make decisions about investing in new assets while facing uncertainty in the generation plans regulatory and environmental constraints and current system endowments in this paper we demonstrate an analytical method for determining the economic value of individual transmission lines in a meshed network by calculating the total welfare effects for the system while many regulators believe that traditional congestion rents provide the correct incentives for investing in transmission upgrades we show that the uncertainty in system conditions breaks down this paradigm the analysis uses an existing security constrained optimal power flow scopf model and a test network to demonstrate how the method can be used to determine the welfare effects of changing the capacity of selected transmission lines the results show that a substantial portion of the economic benefits for an individual line may come from maintaining system reliability when equipment failures occur furthermore these benefits can change dramatically when inherently intermittent sources of renewable generation are added to a network and the changes in benefits are not captured effectively by changes in the expected congestion rents

assessing market structures in resource markets an empirical analysis of the market for metallurgical coal using various equilibrium models abstract the prevalent market structures found in many resource markets consist of high concentration on the supply side and low demand elasticity market results are therefore frequently assumed to be an outcome of strategic interaction between producers common models to investigate the market outcomes and underlying market structures are games representing competitive markets strategic cournot competition and stackelberg structures that take into account a dominant player acting first followed by one or more players we add to the literature by expanding the application of mathematical models and applying an equilibrium problem with equilibrium constraints epec which is used to model multi leader follower games to a spatial market using our model we investigate the prevalent market setting in the international market for metallurgical coal between 2008 and 2010 whose market characteristics provide arguments for a wide variety of market structures using different statistical measures to compare model results with actual market outcomes we find that two previously neglected settings perform best first a setting in which the four largest metallurgical coal exporting firms compete against each other as stackelberg leaders while the remainders act as cournot followers second a setting with bhpb acting as sole stackelberg leader

transmission switching in expansion planning transmission switching ts is introduced to add flexibility to the transmission and generation capacity expansion planning problem ts could improve the performance of the capacity expansion planning model and reduce the total planning cost the capacity expansion planning problem is decomposed into a master problem and two subproblems the master problem utilizes the candidate set for additional generating unit and transmission capacity investments to find the optimal plan throughout the planning horizon the subproblems use the optimal plan apply transmission switching to relieve any transmission flow violations and calculate the optimal dispatch of generating units the transmission network contingencies are also considered in the subproblems the case studies exhibit the effectiveness of the proposed expansion planning approach

financial market development and trade openness evidence from emerging economies international trade is said to be the engine of economic growth despite an enormous effort to explain this phenomenon the relationship between financial market development and trade openness and integration into the world economy is still an enigma this article investigates the relationship between financial market development and trade openness to do this we develop a long run and short run model a bounds testing approach to cointegration for 18 emerging economies over the period 1980 to 2011 estimates from all models show that financial market development including both the stock market and the banking sector has significant effect on trade openness in both short run and long run phenomena in the majority of countries despite many similarities among emerging economies additional evidence suggests that the link between either stock market development or banking sector development with trade openness works via each country s specific structure

impact of network payment schemes on transmission expansion planning with variable renewable generation abstract a large number of studies have dealt with the transmission expansion planning tep problem however few investigations have focused on analyzing the impacts of network payment schemes on network configuration and the benefits losses distribution among the participants in electricity markets in this paper we propose a multi annual transmission expansion planning model considering four different network payment schemes to finance the construction of new transmission lines seeking to reduce the total system costs wind and solar power generation are included in the model taking into account their variability the proposed models are reformulated as mixed integer linear programming milp problems we use seven performance metrics related with congestion nodal prices and generator benefits among others to evaluate the effect of each payment scheme a realistic case study based on the main power system in chile is analyzed to illustrate the proposed models it is shown that integrating line cost recovering equations into the tep model may result into a more realistic and less congested power network also total system cost is highly related with transmission tariff discrimination in that way tariffs with high location dependence perform better in the case studied the chilean power system

the structural reshaping of globalization implications for strategic sectors profiting from innovation and the multinational enterprise the rapid reshaping of the global economic order requires fundamental shifts in international business scholarship and management practice new forms of protectionist policies new types of internationalization motives and new tools of techno nationalism may lead to what we call bifurcated governance at the macro level and value chain decoupling at the micro level as a result innovation networks will require novel reconfigurations we examine the emerging constraints on multinational enterprises imposed by a bifurcated world order we also discuss how the dynamic capabilities framework can guide scholars and managers alike to achieve new forms of evolutionary fitness

network expansion by a proactive transmission system operator a case study abstract complex planning procedures often amplify the difference in investment time between generation and transmission in this work we consider a transmission project in italy and relying on a recently proposed methodology we compare costs and benefits of anticipating the planning process before the connection of new power plants becomes certain whereas the system faces lower congestion costs if the network is reinforced immediately anticipation constitutes a sunk cost in case generation is not built for realistic load and generation scenarios anticipation costs as well as differences in investment times our results indicate that anticipation is the most efficient choice for a relatively low connection probability analyses of this sort are particularly relevant in light of the increasing complexity of public engagement processes and of the remarkable growth in renewable generation

foreign direct investment in industrial research in the pharmaceutical and electronics industries results from a survey of multinational firms abstract this paper examines motives location characteristics inter temporal characteristics and modes of entry for foreign direct investment fdi in research and development r d the paper is based on a detailed empirical survey of laboratory sites established by 32 large multinational companies domiciled in 5 countries findings indicate that fdi in r d has risen considerably over the last 40 years and that firms invest in r d sites abroad in order to augment their knowledge base or in order to exploit it the former motive leads to establishment of facilities primarily close to universities while the latter type leads to establishment of facilities close to existing manufacturing facilities and markets the paper also finds that greenfield investments are the dominant mode of entry and that firms establish multiple r d sites in their home countries before investing in such sites abroad

mnes as border crossing multi location enterprises the role of discontinuities in geographic space spurred by the classic work of dunning mne location has become the focus of a growing body of research in the field in this paper we argue that international business ib research examining the spatial dimension has serious weaknesses stemming from its traditional assumption of the country as the location unit of analysis while border crossing remains the key research context of ib placing it within a general spatial framework that recognizes both international and subnational spatial heterogeneity opens up vast new vistas for research analyzing mnes as border crossing multi location enterprises allows the researcher to distinguish between discrete border effects and continuous distance effects and undertake a more fine grained analysis of location within such analysis national borders may appear as qualitative discontinuities in space that is points at which spatial heterogeneity changes abruptly however subnational spatial heterogeneity is often the characteristic that drives firm strategy as mnes decide to locate in particular agglomerations and not at random locations within a country the complex firms that ib scholars study typically include multiple units within the same country so that a complete analysis requires considering both subnational distance effects as well as international border effects

internal funds and corporate investment in india abstract several economists have argued that capital markets in less developed countries are fragmented fragmented capital markets retard the efficient allocation of resources and force business firms to rely on internal sources of funds using firm level data the authors examine the importance of the accelerator internal funds and depreciation for investment by manufacturing firms in india the results indicate that internal funds and depreciation have significant explanatory power in a sales accelerator model of investment and that there exists heterogeneity among firms in the link between internal funds and investment in particular internal funds are relatively more important for large firms and firms that produce luxury goods

the financial repression liberalization debate taking stock looking for a synthesis financial repression and liberalization became the object of fierce debates between academics and policy makers since the early 1970s as of the late 1980s financial liberalization became also part of the structural adjustment programs sponsored by the international monetary fund and the world bank however the literature on financial repression and liberalization remains controversial on its theoretical conclusions and policy implications given its importance for both the theory and policy of economic development and growth this paper looks for a possible synthesis after reviewing the theoretical contributions and empirical studies under the headings of the mckinnon shaw and new structuralists models the survey concludes that a new synthesis might be found in the post keynesian attempt to take an institutional perspective within a globalised financial and economic environment

internal embeddedness geographic distance and global knowledge sourcing by overseas subsidiaries we investigate determinants of global knowledge sourcing of overseas r d subsidiaries shedding light on vertical cross border embeddedness within firms drawing on the paradox of embeddedness perspective which assumes that embeddedness may facilitate or hinder knowledge transfer we examine the extent to which different types of internal vertical embeddedness administrative versus knowledge facilitate global knowledge sourcing we find that vertical administrative embeddedness inhibits global knowledge sourcing while vertical knowledge embeddedness promotes it we also find differing moderating effects of geographic distance between headquarters and its subsidiaries on the association between vertical embeddedness and global knowledge sourcing

is knowledge power knowledge flows subsidiary power and rent seeking within mncs in recent years as multinational corporation mnc subsidiaries have become more closely linked to international networks their knowledge intensity has risen and some of their r d has gained a more creative role simultaneously and often connectedly many subsidiaries have acquired considerable strategic independence in all aspects of their operations and therefore are able to exercise considerable intra firm bargaining power to influence the distribution of the firm s resources in this context we suggest that intra mnc knowledge flows are a key determinant of subsidiary bargaining power we argue that subsidiary managers can exploit such power to pursue their own ends such rent seeking behavior is implicit in much of the literature on managerialism but our analysis suggests that such behavior can now occur in headquarters subsidiary and subsidiary subsidiary relations thus subsidiary strategic independence designed to enhance the competitiveness of outputs market knowledge and inputs asset seeking and learning can be corroded when the pursuit of subsidiary objectives encourages rent seeking empirical analysis of a sample of high technology subsidiaries in the uk provides strong support for the theory we examine several avenues whereby the incentives of units within the mnc can be aligned

impact of intermittent non conventional renewable generation in the costs of the chilean main power system abstract chile has recently approved a law aiming a target for electricity generation with non conventional renewable energy ncre of 20 by year 2025 it is anticipated that most of this ncre generation will be provided by intermittent energy sources wind and solar photovoltaic pv the economic consequences of intermittent ncre penetration in the chilean central interconnected system sic are assessed the ncre penetration is simulated with a 10 year horizon 2017 2027 considering four scenarios of ncre penetration 10 15 20 and 30 of total generation the authors model the hydro thermal operation of the power system and analyze spot prices total operation costs and capacity factors results show that the average spot price in the sic when having an optimal minimum cost generation mix is 89 7 us mwh as intermittent ncre penetration increases some thermal base load units capacity factors change producing an increase in the generation cost additional transmission capacity is also needed elevating the total cost the average incremental cost of integrating intermittent ncre generation is 65 8 us mwh when increasing ncre penetration from 10 to 30 the effect of fossil fuel price fluctuation is also addressed two policy guidance elements are presented intermittency should be reduced by diversifying the renewable portfolio and penetration costs of intermittent ncre generation have to be incorporated into their investment or operation costs

monetization financial liberalization and economic development barter sector in 1954 55 the monetized sector contributed 69 to the net national product of india the share of the monetized sector increased to 78 6 of the net national product by 1974 75 during this period the explicit objective of monetary policy in india was to help accelerate the pace of economic development in an environment of reasonable price stability there are several versions of the financial liberalization hypothesis but the one put forward by ronald mckinnon is chosen here because of its succinctness and easy amenability to empirical verification 2 mckinnon s theory in essence deals with the effect of financial liberalization on the accumulation of capital through a policy of high real interest rates this formulation has been made operational by estimating the response of real demand for money balances and private investment to alternative rates of return under the implicit assumption that these are the only two alternative forms of assets held by the private sector 3 all this is predicated on the assumption that the effective limitation on the rate of real capital formation is the supply of real savings and not the inadequate willingness to invest most underdeveloped countries have a significant barter sector a reduction in the share of the barter sector can help to further accelerate the accumulation of capital in a barter system a good share of the factors of production is tied up in distribution away from production to achieve the double coincidence required in such a system with the

balancing subsidiary influence in the federative mnc a business network view the contest for intra organisational power in the multinational corporation mnc has gradually become a prominent issue on the research agenda as long as 25 years ago hedlund 1980 investigated the strategic roles of subsidiaries in mncs and doz and prahalad 1981 raised the issue of how difficult it is for headquarters to remain in control of its subsidiaries and to influence their strategies over time since then several researchers have suggested that mncs can be considered to be dispersed structures of power in which the top management s authority does not necessarily result in hierarchical power being the ultimate control mechanism hedlund 1986 forsgren 1989 ghoshal and bartlett 1990 doz and prahalad 1993 ferner and edwards 1995 kristensen and zeitlin 2001 morgan and whitley 2003 birkinshaw and hood 1998 examined the evolution of capabilities at the subsidiary level and recognised that in most corporations there is an internal competition for charter that implies a process of change in subsidiary roles birkinshaw and hood 1998 782 case research has also indicated that changes in the charters of divisions or subsidiaries in mncs constitute a strong feature of horizontal or vertical competition in the corporate marketplace galunic and eisenhardt 1996 birkinshaw and fry 1998 the tension between the headquarters and overseas laboratories caused by the laboratories desire for autonomy and influence is an example of such a competition asaka wa 2001

how much does subnational region matter to foreign subsidiary performance evidence from fortune global 500 corporations investment in china what explains the heterogeneity of foreign subsidiary performance previous studies have emphasized the importance of industry corporate parent and home country effects on the variation of foreign subsidiary performance building on recent international business and economic geography research this study examines the extent to which subnational region effects can also explain such performance variation we empirically decompose the variance of the performance of fortune global 500 corporations subsidiaries in china during 1998 2006 results show that not only are subnational region effects statistically significant in explaining the variation of subsidiary performance but their interactions with industry corporate parent and home country effects are also significant and economically important we further show that subnational region effects tend to be stronger in the period prior to china s wto accession and in the country s less developed subnational regions our findings highlight the importance of considering both the direct and indirect roles of subnational region in shaping firms strategy and performance in international business research

transmission expansion in an oligopoly considering generation investment equilibrium abstract transmission expansion planning tep is a sophisticated decision making problem especially in an oligopolistic electricity market in which a number of strategic price maker producers compete together a transmission system planner who is in charge of making tep decisions requires considering the future generation investment actions however in such an oligopolistic market each producer makes its own strategic generation investment decisions this motivates the transmission system planner to consider the generation investment decision making problem of all producers within its tep model the strategic generation investment problem of each producer can be represented by a complementarity bi level model the joint consideration of all bi level models one per producer characterizes the generation investment equilibrium that identifies the future evolution of generation investment in the market this paper proposes a tri level tep decision making model to be solved by the transmission system planner whose objective is to maximize the social welfare of the market minus the expansion costs and whose constraints are the transmission expansion limits as well as the generation investment equilibrium problem this model is then recast as a mixed integer linear programming problem and solved numerical results from an illustrative example and a case study based on the ieee 14 bus test system demonstrate the usefulness of the proposed approach

review of grid tie micro generation systems without energy storage towards a new approach to sustainable hybrid energy systems linked to energy efficiency abstract this paper reviews the literature on the subject albeit approaching hybrid micro generation power systems from a systems thinking st and cybernetics standpoint viewing them as dynamically complex adaptive systems cas coupled with and supplying to a set of homes termed a sustainable block in a rural setting here homeostatic regulation hr and control play a vital role in reaching efficient equilibrium towards reconciling power supply and demand response management unlike most of the work reviewed in the literature the focus here is on supervisory control of grid connected micro generation systems without energy storage aiming towards building energy efficiency thriftiness and sustainability in energy consumption building on homeostatic control hc principles first introduced by f c schweppe in 1979 the paper explores the concepts of sustainability and sustainable hybrid energy systems shes applied to micro generation focusing on operational aspects rather than on socio economic environmental or regulatory ones a concrete theoretical model for building a shes is presented for a proposed grid connected renewable microgrid the model seeks to reconcile power supply and demand towards efficient equilibrium homeostasis proposing reward based criteria for controlling renewable electricity supply and consumption in rural communities in chile discussion and recommendations are also offered stating that energy sustainability es is essentially a systems issue and one where es is first and foremost a structural organizational and operational property which is in the very nature of the system itself it is built into it rather than explained by exogenous factors

an analysis of the demand for cash balances by the manufacturing firms in a developing economy abstract using cross section data this paper presents the results of an evaluation of the role of cash balances as a factor input in india s manufacturing industries by using a three factor translog cost function for each of the major industries along with duality theory it was possible to estimate the allen partial elasticities of substitution and the own price elasticities of demand for each factor input three significant conclusions are drawn a cash balances and labor are predominantly substitutes and cash balances and capital are by and large complementary implications of this for choice of techniques is analyzed b the interest elasticity of demand for cash varies with industry from 0 0013 to 0 4756 c separability tests indicate that omitting cash balances from the production function would involve a misspecification of the latter

the demand for liquid assets a firm level analysis analysts have exerted considerable effort attempting to demonstrate that the firm demand for liquid assets or money conforms to microeconomic theory the theory itself is splintered along three lines of inquiry a keynesian version stressing the transaction and asset motives 28 33 35 an essentially quantity theory approach 19 6 and an approach which incorporates money into the firm s production function 22 31 7 29 the empirical work used to test these theoretical approaches has a common element a measure of the firm s scale is included usually sales or business receipts and generally a common flaw the use of aggregated data most studies have used industry level data because it is more readily available this forces the analyst to assume that firms within an industry are homogeneous while firms across industries are heterogeneous the authors can then use the typical firm as the unit of analysis the typical firm is a hypothetical construct whose characteristics are statistical means of all firms aggregated within the industrial category while this is a useful assumption the aggregation may hide the influence of the distribution of firms within the industry these distributional impacts may be significant if there are substantial economies of scale or if firm size influences such things as cash management practices and access to financial markets katsimbris and miller 15 have warned that the size distribution of firms within an industry may alter money demand the greater the inequality in sales the lower the industry s demand for money they find no support for the assumption of identical structural specification across industries these observations have been echoed by hunter 12 and by other work of katsimbris and miller 13 14 under such circumstances the use of industry average data may yield misleading conclusions on the firm demand for money any study of firm behavior in this area should at the very least control for industry some time ago vogel and maddala 33 called for empirical studies using firm level data a call which has gone largely unanswered this study attempts to fill this void by using a comprehensive set of firm level data over a five year period but we also attempt to answer several other questions does the presence of foreign ownership alter the firm s demand for liquid assets

economic criteria for planning transmission investment in restructured electricity markets from an economic perspective a common criterion for assessing the merits of a transmission investment is its impacts on social welfare the underlying assumption in using this criterion is that side payments may be used to distribute the social gains among all market players in reality however since the impacts of an electricity transmission project on different players may vary such side payments are rather difficult to implement this paper focuses on different economic criteria that should be considered when planning electricity transmission investments we propose an electricity transmission investment assessment methodology that is capable of evaluating the economic impacts on the various effected stakeholders and account for strategic responses that could enhance or impede the investment s objectives we formulate transmission planning as an optimization problem under alternative conflicting objectives and investigate the policy implications of divergent expansion plans resulting from the planner s level of anticipation of strategic responses we find that optimal transmission expansion plans may be very sensitive to supply and demand parameters we also show that the transmission investments have significant distributional impact creating acute conflicts of interests among market participants we use a 32 bus representation of the main chilean grid to illustrate our results

linear complementarity models of nash cournot competition in bilateral and poolco power markets two cournot models of imperfect competition among electricity producers are formulated as mixed linear complementarity problems lcps and a simple example is presented to illustrate their application the two models simulate bilateral markets the models include a congestion pricing scheme for transmission but other transmission pricing approaches can also be represented in this framework the two models differ from each other in that one has no arbitrage between nodes of the network while in the other model arbitragers erase any noncost based differences in price the latter bilateral model turns out to be equivalent to a cournot model of a poolco the models differ from other cournot market models in that they include both of kirchhoff s laws via a dc approximation can include arbitragers possess unique solutions and are readily solved by efficient lcp algorithms the key assumption that permits their formulation as lcps is that each producer naively assumes that its output will not affect transmission prices

a transmission planning framework considering future generation expansions in electricity markets this paper proposes a transmission planning framework in a market environment in which only the generation sector is deregulated the proposed framework is based on modeling generation companies gencos strategic behavior and anticipating their expansion patterns from the viewpoint of a transmission system planner the transmission expansion planning problem in this paper is modeled as a four level optimization problem a solution method based on agent based systems and search based optimization techniques is proposed to determine the optimal transmission expansion plan

building a bric stock market opening and investment finance in india since liberalization portfolio equity inflows have been a feature of india s improved growth performance in recent years this study examines a possible connection through the equity financing of capital formation by manufacturing firms emphasis is placed on the funding preferences of owner controlled enterprises with the empirical results connecting equity issues to the management of gearing and the availability of internal funds this context suggests strongly that equity and debt are complementary choices although two channels of influence macroeconomic and allocative combine to encourage investment spending with pro cyclical implications

evaluating interconnector investments in the north european electricity system considering fluctuating wind power penetration with increasing amounts of power generation from intermittent sources like wind transmission planning has not only to account for the expected load curve but also for the stochasticity of volatile power infeeds moreover investments in power generation are no longer centrally planned in deregulated power markets but rather decided on competitive grounds by individual power companies this poses particular challenges when it comes to evaluating the benefits of increased interconnection capacities in large scale systems like the european transmission system within this article an approach is presented which allows assessing the benefits of interconnector investments in the presence of stochastic power infeed and endogenous power plant investments this model uses typical days and hours as well as recombining trees to represent both load and infeed fluctuations an application is presented covering 30 european countries and simultaneously optimizing generation investments and dispatch as well as utilization of transmission lines the model is used to evaluate the benefits of further line extensions between the european mainland and northern european countries we compute welfare gains and the distribution of these gains within a business as usual scenario up to 2030

coordination of generation and transmission development through generation transmission charges a game theoretical approach transmission charges aim to recover the cost of transmission network investments and provide efficient locational signals to new generators in this paper we investigate the effect of these charges on the development of new generation capacities in the system generation expansion planning is decided by strategic generation planners sgps trying to maximize their profits while transmission line investments are planned by a central planner and regulatory body aimed at minimizing the overall operation and network investment costs of the system regulatory transmission charges rtcs are calculated according to the marginal responsibility of generation investment on transmission network investment costs an iterative algorithm is proposed to model the interaction taking place between the central planner and sgps the developed methodology is applied to a 2 node illustrative example and the ieee rts96 and effects of rtcs on investment decisions of sgps are analyzed
