risk limiting economic dispatch for electricity markets with flexible ramping products the expected increase in the penetration of renewables in the approaching decade urges the electricity market to introduce new products in particular flexible ramping products to accommodate the renewables variability and intermittency a risk limiting economic dispatch scheme provides the means to optimize the dispatch and provision of these products in this paper we adopt the extended loss of load probability as the definition of risk we first assess how the new products distort the optimal economic dispatch by comparing to the case without such products specifically using parametric analysis we establish the relationship between the minimal generation cost and the two key parameters of the new products the up and down flexible ramping requirements such relationship yields a novel routine to efficiently solve the non convex risk limiting economic dispatch problem both theoretical analysis and simulation results suggest that our approach may substantially reduce the cost for incorporating the new products we believe our approach can assist the isos with utilizing the ramping capacities in the system at the minimal cost

innovation organizational capabilities and the born global firm we investigate born global firms as early adopters of internationalization that is companies that expand into foreign markets and exhibit international business prowess and superior performance from or near their founding our explication highlights the critical role of innovative culture as well as knowledge and capabilities in this unique breed of international entrepreneurial firm case studies are analyzed to better understand the early internationalization phenomenon and reveal key orientations and strategies that engender international success among these innovative firms case findings are then validated in a survey based study despite the scarce resources typical of young firms our findings reveal that born global firms leverage a distinctive mix of orientations and strategies that allow them to succeed in diverse international markets findings have important implications for the internationalization of contemporary firms

does entry size matter the impact of the life cycle and technology on firm survival a wave of empirical studies has recently emerged showing that smaller scale entry is confronted with a lower likelihood of survival than their larger counterparts the purpose of this paper is to examine whether the relationship between size of a firm when entering an industry and the likelihood of survival holds under different technological conditions and across the different stages of the industry life cycle the empirical evidence suggests that the relationship between firm size and the likelihood of survival is shaped by technology and the stage of the industry life cycle while the likelihood of survival confronting small entrants is generally less than that confronting their larger counterparts the relationship does not hold for mature stages of the product life cycle or in technologically intensive products in mature industries that are still technologically intensive entry may be less about radical innovation and possibly more about filling strategic niches thus negating the impact of entry size on the likelihood of survival

seeking commonalities or avoiding differences re conceptualizing distance and its effects on internationalization decisions past research established distance s key influence on internationalization however theoretical issues methodological challenges and inconsistent results hinder scholarship on why distance plays such an influential role to address these problems we draw from cognitive research on similarity comparisons to re conceptualize distance and test a model of internationalization decisions analyzing the verbal protocols of executives considering a series of internationalization opportunities we demonstrate that over and above objective distance indicators considerations that reduce distance commonalities and considerations that augment distance differences have distinct effects on decisions of where when and how to internationalize as such our study contributes new insights for understanding the nature and effects of distance across different dimensions of distance and internationalization decisions moreover internationalization theories have come to emphasize different theoretical rationales for explaining the influential role of distance on different decisions by integrating these rationales together with the notion that distance reducing commonalities and distance augmenting differences have distinct implications for internationalization decisions we introduce the notion that it is not only the addition of distance considerations that matters but also the directionality of such changes doing so our study points to new theoretical and methodological insights to help address prior criticisms and advance future research

an examination of the influence of industry structure on eight alternative measures of new venture performance for high potential independent new ventures abstract this study examined the influence of the structure of new ventures entered industries on eight alternative measures of new venture performance for 199 high potential independent new ventures each of the 199 entrepreneurial ventures had undertaken an initial public offering ipo within the first 6 years of the venture s founding date and were free of corporate sponsorship or prior corporate parentage specifically this research examined the influence of 1 stage of the life cycle 2 industry concentration 3 entry barriers and 4 product differentiation on eight alternative measures of new venture performance the eight measures of new venture performance examined in this research consisted of 1 change in sales 2 sales level 3 net profit 4 earnings before interest and taxes 5 return on sales 6 return on assets 7 return on invested capital and 8 return on equity most prior research examining the influence of industry structure on new venture performance has 1 utilized only one or two measures of new venture performance as indicators of the venture s overall effectiveness and efficiency 2 often failed to provide theoretical justification for the measure s of new venture performance or industry structure examined and 3 utilized data derived from questionnaires and or the pims data base of corporate sponsored new ventures in addition prior industry structure studies examining independent new ventures have often utilized relatively small sample sizes this study sought to advance the progress in the field of entrepreneurship with regard to understanding the influence of the structure of new ventures entered industries on new venture performance by 1 examining eight alternative measures of new venture performance 2 providing theoretical justification for the measures of new venture performance and industry structure examined and 3 utilizing the largest nonquestionnaire data base of independent new ventures developed to date this research found that the stage of the life cycle of the venture s entered industry was the most important determinant of new venture performance among the four industry structural elements examined stage of the life cycle had a statistically significant relationship at a 0 05 level with the majority of the new venture performance measures examined in this research in addition ventures entering industries in the introductory stage of the life cycle achieved the highest levels of venture performance particularly when compared with those ventures that entered industries in the mature stage of the life cycle however this study did not find a statistically significant relationship between stage of the life cycle and change in sales this suggests that there is a trade off between profitability and sales growth and that new ventures that undertake an ipo have a stronger focus on achieving profitable operations rather than sales growth during the initial years after their ipo this may be due to pressures placed on the new ventures to achieve profitability by the external credit market conversely this research found that 1 industry concentration 2 entry barriers and 3 product differentiation did not have statistically significant relationships at a 0 10 level with any of the eight alternative measures of new venture performance examined in this research however this research did find that over 90 of the new ventures entered industries characterized by 1 a low degree of industry concentration and 2 a high degree of product differentiation the relative absence of new venture entry into industries characterized by 1 high degrees of concentration and 2 low degrees of product differentiation provides support for prior theory which suggests that successful entry into such industry environments may be substantially more difficult in sum the results of this research suggest that high potential independent new ventures that undertake an ipo should enter industries in the introductory stage of the life cycle in addition the results of this research suggest that industries characterized by 1 relatively low degrees of industry concentration and 2 highly heterogenous products may be necessary but not sufficient conditions for successful entry by high potential independent new ventures seeking to raise equity capital through an ipo

the psychic distance paradox companies tend to begin their internationalization process in countries that are psychically close researchers describe the sequence of entry that firms follow and the mode of entry they choose they suggest that psychically close countries are more easily understood than distant ones and offer more familiar operating environments although not prescriptive an unstated conclusion can be drawn linking sequence of entry to performance evidence from thirty two canadian retail companies shows that only seven 22 were functioning successfully in the united states the psychic distance paradox is that operations in psychically close countries are not necessarily easy to manage because assumptions of similarity can prevent executives from learning about critical differences moreover empirical evidence from 271 ceos confirms greater cultural differences between canada and the u s than assumed previously modifications are suggested to improve the psychic distance concept

entrepreneurial proclivity capability upgrading and performance advantage of newness among international new ventures in spite of a notable interest surrounding the learning advantages of newness lan centered on the emergent international entrepreneurship literature we have only limited understanding of how young international new ventures invs acquire learning advantages and avoid the liabilities of newness and foreignness in order to achieve lan related performance from early internationalization in this article two related but conceptually distinct capability upgrading constructs knowledge capability upgrading and network capability upgrading are identified to serve as mediating mechanisms that link entrepreneurial proclivity and lan related performance our findings from a sample of 436 young invs from china provide supporting evidence for the mediating effect of capability upgrading particularly among relatively larger new ventures and those operating with cost price advantages in the international marketplace this study fills a gap in the under researched area of literature surrounding invs from emerging economies and demonstrates how young international venturing firms can leverage the entrepreneurial dynamics of learning to achieve growth opportunities from early internationalization

scheduling and pricing for expected ramp capability in real time power markets higher variable renewable generation penetrations are occurring throughout the world on different power systems these resources increase the variability and uncertainty on the system which must be accommodated by an increase in the flexibility of the system resources in order to maintain reliability many scheduling strategies have been discussed and introduced to ensure that this flexibility is available at multiple timescales to meet variability that is the expected changes in system conditions two recent strategies have been introduced time coupled multi period market clearing models and the incorporation of ramp capability constraints to appropriately evaluate these methods it is important to assess both efficiency and reliability but it is also important to assess the incentive structure to ensure that resources asked to perform in different ways have the proper incentives to follow these directions which is a step often ignored in simulation studies we find that there are advantages and disadvantages to both approaches we also find that look ahead horizon length in multi period market models can impact incentives this paper proposes scheduling and pricing methods that ensure expected ramps are met reliably efficiently and with associated prices based on true marginal costs that incentivize resources to do as directed by the market case studies show improvements of the new method

the dynamic value of mne political embeddedness the case of the chinese automobile industry this paper examines the complex relationship between the embeddedness of multinational enterprises mnes in host country political networks and their long run competitive positions in host emerging markets we report the findings of a longitudinal study of the chinese automobile sector from the early 1980s to the mid 2000s using data from 142 interviews over 11 years and a wide range of secondary sources we explore the process through which the value of political embeddedness changed over time in the face of profound and rapid changes in host country business environments on the basis of this longitudinal study the paper unravels the underlying mechanisms that lead to the declining and even negative value of deep political embeddedness by mnes in a politically stable emerging economy

firm and industry effects within strategic management an empirical examination this study brings out the complementarities between resource based and industrial organization schools within strategic management through an empirical examination of firm and industry effects a variance component analysis of 264 single business companies from 69 industries using 5 and 15 year periods suggests that firm effects are more important than industry effects on firm performance but not on core strategies such as technology and marketing the findings also point to the need to study core strategies at lower levels of aggregation to understand the sources of competitive advantage 1998 john wiley sons ltd

causes of the difficulties in internationalization we study the causes of the difficulties faced by firms when they internationalize in search of new markets we build on the resource based theory to argue that the difficulties in internationalization can be separated into three main sets based on their relationship to advantage loss of advantage provided by resources transferred abroad creation of a disadvantage by resources transferred abroad and lack of complementary resources required to operate abroad in each set we further distinguish difficulties that are specific to a firm from those that are common to a set of firms we argue that only a few of the resulting types of difficulties of internationalization are exclusive to the cross border expansion and propose solutions that address the root cause of each type

assessing environmental economic and reliability impacts of flexible ramp products in miso s electricity market abstract increased variability and uncertainty of net electrical load due to high penetration of wind and solar power augments the need for dispatching conventional generators with sufficient ramping capability rc needed to balance demand with supply having sufficient rc reduces the need of last minute dispatch schedule modifications which cause cost reliability and environmental outcomes that reduce the benefits of renewables the midcontinent independent system operator miso has modified its unit commitment and economic dispatch algorithms to account for the economic value of provisioning adequate rc levels this paper explores the outcomes of this modified market clearing process by simulating 10 minute operations of a scaled miso test system for three representative months under low and high wind penetration scenarios changes in system performance are quantified by comparing system costs scarcity events pricing energy prices generation fuel mix wind power curtailment and co 2 emissions between the conventional market clearing algorithm and one with flexible rc products results indicate that adding rc products lowers co 2 emissions and system costs facilitates wind integration and improves reliability these benefits are robust to changes in the market clearing algorithm parameters such as over under generation penalties and reserve scarcity prices

input subsidies cash constraints and timing of input supply is low input use by poor smallholder farmers caused by time inconsistent behavior or by limited ability to buy inputs are input subsidies the best solution to stimulate input demand or are there smarter solutions these issues are investigated by combining survey data stated preference questions and randomized experiments in malawi the demand for fertilizer at harvest time and at planting time farm gate shadow prices for fertilizer and the gap between the willingness to accept wta and willingness to pay wtp prices for a standard input package were investigated significant effects of timing and of cash constraints were found suggesting the possibility that smarter designs exist such as distribution of smaller packages from harvest time to planting time

dynamic capabilities what are they this paper focuses on dynamic capabilities and more generally the resource based view of the firm we argue that dynamic capabilities are a set of specific and identifiable processes such as product development strategic decision making and alliancing they are neither vague nor tautological although dynamic capabilities are idiosyncratic in their details and path dependent in their emergence they have significant commonalities across firms popularly termed best practice this suggests that they are more homogeneous fungible equifinal and substitutable than is usually assumed in moderately dynamic markets dynamic capabilities resemble the traditional conception of routines they are detailed analytic stable processes with predictable outcomes in contrast in high velocity markets they are simple highly experiential and fragile processes with unpredictable outcomes finally well known learning mechanisms guide the evolution of dynamic capabilities in moderately dynamic markets the evolutionary emphasis is on variation in high velocity markets it is on selection at the level of rbv we conclude that traditional rbv misidentifies the locus of long term competitive advantage in dynamic markets overemphasizes the strategic logic of leverage and reaches a boundary condition in high velocity markets copyright 2000 john wiley sons ltd

true and spurious duration dependence the identifiability of the proportional hazard model lancaster and nickell 1980 have argued that in the proportional hazard model the effects of time dependence true duration dependence and unobserved sample heterogeneity spurious duration dependence cannot be distinguished we show that both effects can be distinguished if the model allows for observed explanatory variables in the hazard we also discuss the application of our result to practical situations

effects of social capital and power on surviving transformational change the case of initial public offerings we examined how social capital and the power of venture capitalists and founderceos affect ipo firm survival using data from 218 u s initial public offerings conducted in 1992 we found that average management team tenure and an ipo deal s network embeddedness decreased the likelihood of failure during a firm s first five years as a public entity founder ceo presence at the time of an ipo interacted with ceo ownership to decrease the likelihood of failure and ceo ownership and venture capitalist ownership concentration also decreased that likelihood evolutionary perspectives on organizations are often accompanied by the presumption that organizations face an increased risk of failure early in their lives owing to liabilities of newness aldrich 1999 stinchcombe 1965 as organizational goals and patterns of activity become routinized over time increased reliability in performance and accountability for actions taken enhance a firm s survival chances hannan freeman 1984 this process however also generates strong inertial pressures that not only discourage organizational change but also because of the potential for disruption to existing internal and external routines make change hazardous research findings suggest that even in older better established firms significant transformational events during their life cycles can effectively reset the clock and reintroduce risks associated with the liability of newness as firms struggle to adapt strategies internal operational and administrative processes and or external ties and relationships amburgey kelly barnett 1993 thus transformational change in organizational operations decreases efficiency and increases failure rates at least in the short term as resources and attention are diverted from normal routinized operating functions to processes involving adaptation and reorientation haveman 1992

which ties matter when the contingent effects of interorganizational partnerships on ipo success this paper investigates the contingent value of interorganizational relationships at the time of a young firm s initial public offering ipo we compare the signaling value to young firms of having ties with two types of interorganizational partnerships endorsement relationships such as those with venture capital firms and investment banks and strategic alliance partnerships we propose that under different equity market conditions potential investors in an issuing firm attend to different types of uncertainty attention to these different types of uncertainty affects investors perceptions of the relative value of a young firm s different kinds of endorsements and partnerships and hence ipo success results from a sample of young biotechnology firms show that ties to prominent venture capital firms are particularly beneficial to ipo success during cold markets while ties to prominent investment banks are particularly beneficial to ipo success during hot markets a firm s strategic alliances with major pharmaceutical health care firms did not have such contingent effects implications for understanding the contingent value of interorganizational ties are discussed copyright 2003 john wiley sons ltd

economic and environmental implications of different approaches to hedge against wind production uncertainty in two settlement electricity markets a pjm case study abstract this paper examines the economic and environmental outcomes of four two settlement electricity market clearing designs the first design corresponds to a deterministic market clearing dmc similar to the mechanism currently used in organized wholesale electricity markets in the united states the other three designs account for the day ahead da wind power production uncertainty into the da market mechanisms either implicitly or explicitly an augmented deterministic market clearing admc design introduces da ramp capability products these products ensure adequate and ramp feasible electricity generation capacity commitments in the da stage to cope with the real time realization of wind power generation a hybrid deterministic market clearing hdmc design augments admc by explicitly integrating a characterization of wind power production uncertainty into the residual unit commitment ruc process which is run after the da market is closed using stochastic programming the last design referred to as stochastic market clearing smc uses stochastic optimization to explicitly account for wind power production uncertainty in the da market clearing mechanisms i e da unit commitment and economic dispatch the four market clearing designs are assessed by simulating the electricity market operations of a test system and comparing their results in terms of operating costs prices costs and revenues of different types of producers consumer s payments integration of wind power and air emissions the test system has 12 of the capacity of pjm s fossil fired power generation fleet and uses data on coincident demand and wind power production from the bonneville power administration bpa system during years 2010 2014 the simulations are performed hourly for a whole year results show that smc is superior as its costs reductions are more than two times the improvements attained by admc and hdmc also smc results in electricity prices that are better aligned with operation costs cuts the spread between the day ahead and real time prices by 40 reduces out of market short term revenue sufficiency payments by 58 reduces co2 emissions by 3 52 and decreases power plants cycling hdmc is a distant second best market design relative to dmc it achieves a reduction in total costs that is less than half the reduction achieved by smc a reduction in out of market payments that is 80 of the reduction attained by smc and an increase in wind power integration that is

timing is everything curvilinear effects of age at entry on new firm growth and survival and the moderating effect of ipo performance abstract theory suggests that an earlier age at international entry results in improved growth but also decreased survival chances empirical studies tell a different story providing mixed and equivocal results that challenge the tenets of extant theory to begin to bridge the gap between theory and results we develop theoretical explanations for curvilinear inverted u shaped relationships between age at entry and both firm growth and firm survival as well as the moderating impact of resource providing initial public offering ipo on the resource intensive internationalization process our findings support the inverted u shaped relationships and that ipo performance steepens the growth curve and flattens the survival curve taken together our study enhances understanding of the effects of age at entry bridges the ipo and international entrepreneurship literatures and offers avenues for extending the micro foundations of the development of capabilities for new foreign market entry in doing so we advance knowledge about the conditions under which earlier or later internationalization leads some firms to thrive while others fail

the born global firm an entrepreneurial and capabilities perspective on early and rapid internationalization our 2004 journal of international business studies article innovation organizational capabilities and the born global firm provided a framework for the phenomenon of early and rapid internationalization among young entrepreneurial firms this work can be characterized as an integration of marketing entrepreneurial and capability based thinking around exporting positioned as the born global exporter the article also reported findings from a national study of start up firms that expanded abroad early in their evolution in the present commentary we reflect on the contributions of the 2004 article review the scholarship on the topic over the past decade and offer suggestions for future inquiry while the incidence of early internationalization by firms was a novel concept two decades ago today such firms are found in abundance in many countries yet many unresolved research questions remain including the crucial topic of what happens to born global firms as they grow and mature over time similarly the issue of why some firms internationalize early others late in their evolution and still others choose to remain local is a fundamental question for international business scholarship

the uppsala internationalization process model revisited from liability of foreignness to liability of outsidership the uppsala internationalization process model is revisited in the light of changes in business practices and theoretical advances that have been made since 1977 now the business environment is viewed as a web of relationships a network rather than as a neoclassical market with many independent suppliers and customers outsidership in relation to the relevant network more than psychic distance is the root of uncertainty the change mechanisms in the revised model are essentially the same as those in the original version although we add trust building and knowledge creation the latter to recognize the fact that new knowledge is developed in relationships
