competition cooperation and innovation organizational arrangements for regimes of rapid technological progress abstract discussions of the link between firm size and innovation are outmoded because the boundaries of the firm have become fuzzy in recent decades strategic alliances constellations of bilateral agreements among firms are increasingly necessary to support innovative activities such alliances can facilitate complex coordination beyond what the price system can accomplish while avoiding the dysfunctional properties sometimes associated with hierarchy antitrust law and competition policy need to recognize that these new organizational forms are often the functional antithesis of cartels though they may have certain structural similarities a more complete understanding of bilateral contracts and agreements ought to reveal when and how cooperation can support rather than impede innovation and competition

in love with the debit card but still married to cash abstractusing shopping diary survey data we show that changing payment patterns is a challenging task even when consumers have fallen in love with a new payment instrument they find it hard to divorce from their old payment instrument we find a discrepancy between how consumers prefer to pay and how they actually pay half of the consumers who prefer the debit card to cash don t use the debit card to pay a majority of their point of sale transactions our regression results show that the habit of paying cash plays a significant role explaining the presence of a gap

artificial adaptive agents in economic theory economic analysis has largely avoided questions about the way in which economic agents make choices when confronted by a perpetually novel and evolving world as a result there are outstanding questions of great interest to economics in areas ranging from technological innovation to strategic learning in games this is so despite the importance of the questions because standard tools and formal models are ill tuned for answering such questions however recent advances in computer based modeling techniques and in the subdiscipline of artificial intelligence called machine learning offer new possibilities artificial adaptive agents aaa can be defined and can be tested in a wide variety of artificial worlds that evolve over extended periods of time the resulting complex adaptive systems can be examined both computationally and analytically offering new ways of experimenting with and theorizing about adaptive economic agents many economic systems can be classified as complex adaptive systems such a system is complex in a special sense i it consists of a network of interacting agents processes elements ii it exhibits a dynamic aggregate behavior that emerges from the individual activities of the agents and iii its aggregate behavior can be described without a detailed knowledge of the behavior of the individual agents an agent in such a system is adaptive if it satisfies an additional pair of criteria the actions of the agent in its environment can be assigned a value performance utility payoff fitness or the like and the agent behaves so as to increase this value over time a complex adaptive system then is a complex system containing adaptive agents networked so that the environment of each adaptive agent includes other agents in the system complex adaptive systems usually operate far from a global optimum or attractor such systems exhibit many levels of aggregation organization and interaction each level having its own time scale and characteristic behavior any given level can usually be described in terms of local niches that can be exploited by particular adaptations the niches are various so it is rare that any given agent can exploit all of them as rare as finding a universal competitor in a tropical forest moreover niches are continually created by new adaptations it is because of this ongoing evolution of the niches and the perpetual novelty that results that the system operates far from any global attractor improvements are always possible and indeed occur regularly the everexpanding range of technologies and products in an economy or the everimproving strategies in a game like chess provide familiar examples adaptive systems may settle down temporarily at a local optimum where performance is good in a comparative sense but they are usually uninteresting if they remain at that optimum for an extended period a theory of complex adaptive systems based on aaa makes possible the development of well defined yet flexible models that exhibit emergent behavior such models can capture a wide range of economic phenomena precisely even though the development of a general mathematical theory of complex adaptive systems is still in its early stages the aaa models complement current theoretical directions they are

temporal aggregation in political budget cycles electoral cycles have been widely debated since the pioneering studies of the 1970s on monetary and fiscal policy 1 drazen sums up the evidence in terms of active fiscal policy and passive monetary policy while expansionary fiscal policy is the main impulse behind electoral cycles monetary policy has an accommodating role 2 recently there has been a flurry of empirical work on political budget cycles pbcs using cross country panels the most influential works concentrate on the budget surplus because it can capture both increases in expenditures and tax cuts before elections and is thus the most sensitive indicator of aggregate pbcs 3a drawback of these extant studies is their reliance on annual observations since elections take place between january and december annual data do not allow one to identify the election year precisely to get around this problem other schemes have been proposed for example by the rule of the semester the previous year is counted as the election year if elections take place before july 4 what are the consequences of temporal aggregation for the measurement of pbcs instead of being concentrated in the election year pre electoral effects may be spread out over the two years leading up to elections more important if the sign of policies is reversed after elections lower frequency data may mask pbcs because the effects in the election year cancel out as akhmedov and zhuravskaya point out in their country study of russia 5to illustrate the differences between using annual and quarterly data to identify the election year imagine that elections take place in june furthermore assume there is a pre electoral deterioration in the budget surplus surplus 1 during the four quarters running up to elections followed by an improvement surplus 1 the next four quarters in the calendar year in which elections take place the net effect on the budget surplus is zero elections are not always in june of course what happens if elections are evenly spread out over the year table 1 presents a simulation where y 0 is the calendar year of elections y 1 is the year before and y 1 is the year after for elections in the first quarter of the election year namely y 0 q 1 our textbook example of a pre electoral expansion in the deficit during the four quarters prior to elections followed by a contraction the next four quarters implies that the surplus equals 1 from y 1 q 2 to y 0 q 1 it equals 1 from y 0 q 2 to y 1 q 1 and it equals 0 otherwise when the budget surplus is at its average value normalized here at zero the same procedure is followed for elections in the other three quarters if we aggregate the effects by calendar year there is a serious underestimation of pbcs in the election year since pre electoral expansions are almost cancelled out by post electoral contractions leaving a net expansive effect that is only 25 percent of the total stimulus before elections the least affected by temporal aggregation are post electoral fiscal adjustments since 62 5 percent of the total effect is reflected the year after elections on the other hand if there were no post electoral fiscal adjustments the problem of temporal aggregation would be much less severe since 62 5 percent of the total expansive effect would be reflected the calendar year of elections and 37 5 percent the year before this paper tackles the issue of temporal aggregation in pbcs head on we build a cross country panel with annual and quarterly data from nineteen latin american countries and twenty member states of the organization for economic cooperation and development oecd over the 1980 2005 period 6 quarterly data allow us to identify the election year more precisely with annual data the election year is the calendar year in which elections take place with quarterly data the election year comprises the election quarter plus the three prior quarters we introduce two nonstandard features in our analysis

do fiscal rules dampen the political business cycle this paper develops and tests the theory that fiscal rules limit politicians ability to manipulate the budget for electoral gain using panel data from the american states i find evidence suggesting that stringent balanced budget rules dampen the political business cycle that is while spending rises before and falls after elections in states that can carry deficits into the next fiscal year this pattern does not exist in states with strict no carry rules neither binding gubernatorial term limits nor the partisan composition of government appear to significantly affect the magnitude of the political business cycle

political business cycles 40 years after nordhaus the aim of this article is to survey the huge literature that has emerged in the last four decades following nordhaus s rev econ stud 42 2 169 190 1975 publication on political business cycles pbcs i first propose some developments in history of thought to examine the context in which this ground breaking contribution saw the light of the day i also present a simplified version of nordhaus s model to highlight his key results i detail some early critiques of this model and the fields of investigations to which they gave birth i then focus on the institutional context and examine its influence on pbcs the actual research agenda finally i derive some paths for future research

voters as fiscal conservatives voters penalize federal and state spending growth this is the central result of my analysis of voting behavior in presidential senatorial and gubernatorial elections from 1950 1988 the composition of federal spending growth seems irrelevant the vote loss to the president s party from an extra dollar of defense or nondefense spending is the same however in gubernatorial elections expansion of state welfare spending exacts a disproportionate political price deficit financing of federal or state spending does not appear to matter politically i conclude by discussing the obvious question of why government budgets have grown in the face of this voter hostility

interorganizational alliances and the performance of firms a study of growth and innovation rates in a high technology industry this paper investigates the relationship between intercorporate technology alliances and firm performance it argues that alliances are access relationships and therefore that the advantages which a focal firm derives from a portfolio of strategic coalitions depend upon the resource profiles of its alliance partners in particular large firms and those that possess leading edge technological resources are posited to be the most valuable associates the paper also argues that alliances are both pathways for the exchange of resources and signals that convey social status and recognition particularly when one of the firms in an alliance is a young or small organization or more generally an organization of equivocal quality alliances can act as endorsements they build public confidence in the value of an organization s products and services and thereby facilitate the firm s efforts to attract customers and other corporate partners the findings from models of sales growth and innovation rates in a large sample of semiconductor producers confirm that organizations with large and innovative alliance partners perform better than otherwise comparable firms that lack such partners consistent with the status transfer arguments the findings also demonstrate that young and small firms benefit more from large and innovative strategic alliance partners than do old and large organizations copyright 2000 john wiley sons ltd

fiscal transparency political parties and debt in oecd countries abstract many believe and argue that fiscal or budgetary transparency has large positive effects on fiscal performance however the evidence linking transparency and fiscal policy outcomes is less compelling to analyze the effects of fiscal transparency on public debt accumulation we present a career concerns model with political parties this allows us to integrate as implications of a single model three hitherto separate results in the literature on deficit and debt accumulation that transparency decreases debt accumulation at least by reducing an electoral cycle in deficits that right wing governments at least for strategic reasons tend to have higher deficits than left wing governments and that increasing political polarization increases debt accumulation to test the predictions of the model we construct a replicable index of fiscal transparency on 19 country oecd data simultaneous estimates of debt and transparency strongly confirm that a higher degree of fiscal transparency is associated with lower public debt and deficits independent of controls for explanatory variables from other approaches

elections and the timing of devaluations this paper presents a rational political budget cycle model where devaluation acts as a tax on consumption due to a cash in advance constraint competent governments can signal their competency by reducing the rate of devaluation prior to elections when voters also ignore the degree to which governments are opportunistic i e the extent to which they are willing to distort the economy for electoral gain an incompetent opportunistic incumbent can reduce the rate of devaluation in the run up to an election the main theoretical implication in either setup that the rate of devaluation is significantly higher in the months following an election is consistent with evidence drawn from 26 countries in latin america d 2003 elsevier b v all rights reserved

separation of powers and political budget cycles political budget cycles pbcs arise when the electorate is imperfectly informed about the incumbent s competence and the incumbent has discretion over the budget focusing on the second condition we study how separation of powers affects pbcs in the composition of government spending we find that the details of the budget process namely the bargaining rules the status quo s location and the degree of compliance with the budget law are critical for the existence and the amplitudes of pbcs in particular when the status quo is determined by the previous budget and there is high compliance with the budget law separation of powers acts as a commitment device which solves the credibility problems that drive pbcs

equilibrium political budget cycles political business cycle theories generally rely on nominal rigidities and voter myopia this paper offers an equilibrium theory that preserves some basic insights from earlier models though with significant refinements the political budget cycle emphasized here is in fiscal policy rather than output and inflation it arises via a multidimensional signal process one can consider the welfare implications of proposals to mitigate the cycle and the effects of altering the electoral structure copyright 1990 by american economic association

incumbents use of pre entry alliances before expansion into new technical subfields of an industry industry incumbents frequently delay entry into emerging technical subfields fearing product cannibalization and uncertain investment and enter only after technical and market uncertainties have subsided we predict that many incumbents particularly stronger firms will participate in alliances with other firms before their standalone entry the alliances will be used to realize part of the value of specialized assets and to gain information about the emerging products and markets we support the predictions with evidence from the us market of the medical diagnostic imaging industry

innovation and cooperation implications for competition and antitrust n k robel laureate robert solow and his colleagues on mit s industrial productivity commission recently noted dertouzos lester and solow 1989 p 7 undeveloped cooperative relationships between individuals and between organizations stand out in our industry studies as obstacles to technological innovation and the improvement of industrial performance and later p 105 that interfirm cooperation in the u s has often though not always been inhibited by government antitrust regulation these striking conclusions warrant further exploration unfortunately industrial organization textbooks still discuss horizontal cooperation and competition almost exclusively in terms of standard cartel theory on the other hand vertical cooperation contracting is viewed differently and some textbooks provide treatments of supplier buyer relationships in which cooperation is viewed as enhancing efficiency both in the textbooks and in policy discussion among economists cooperation among competitors is highly suspect being perhaps the last bastion of what was once referred to as the inhospitality tradition in antitrust as a result very little literature addresses how cooperation among competitors can promote competition notwithstanding that cooperation among competitors may sometimes be essential if innovating firms are to compete in today s increasingly global markets imai and baba 1989 such cooperation is already important in japan and in europe 1

network location and learning the influence of network resources and firm capabilities on alliance formation this paper presents a dynamic firm level study of the role of network resources in determining alliance formation such resources inhere not so much within the firm but reside in the interfirm networks in which firms are placed data from extensive fieldwork show that by influencing the extent to which firms have access to information about potential partners such resources are an important catalyst for new alliances especially because alliances entail considerable hazards this study also assesses the importance of firms capabilities with alliance formation and material resources as determinants of their alliance decisions i test this dynamic framework and its hypotheses about the role of time varying network resources and firm capabilities with comprehensive longitudinal multi industry data on the formation of strategic alliances by a panel of firms between 1970 and 1989 the results confirm field observations that accumulated network resources arising from firm participation in the network of accumulated prior alliances are influential in firms decisions to enter into new alliances this study highlights the importance of network resources that firms derive from their embeddedness in networks for explaining their strategic behavior copyright 1999 john wiley sons ltd

learning from competing partners outcomes and durations of scale and link alliances in europe north america and asia this paper investigates the outcomes and durations of strategic alliances among competing firms using alliance outcomes as indicators of learning by partner firms we show that alliance outcomes vary systematically across link and scale alliances link alliances are interfirm partnerships to which partners contribute different capabilities while scale alliances are partnerships to which partners contribute similar capabilities we find that partners are more likely to reorganize or take over link alliances than scale alliances by contrast scale alliances are more likely to continue without material changes the two types of alliances are equally likely to shut down at similar ages these results support the view that link alliances lead to greater levels of learning and capability acquisition between the partners than do scale alliances copyright 2000 john wiley sons ltd

transparency political polarization and political budget cycles in oecd countries we investigate the effects of fiscal transparency and political polarization on the prevalence of electoral cycles in fiscal balance while some recent political economy literature on electoral cycles identifies such cycles mainly in weak and recent democracies in contrast we show conditioning on a new index of institutional fiscal transparency that electoral cycles in fiscal balance are a feature of many advanced industrialized economies using a sample of 19 oecd countries in the 1990s we identify a persistent pattern of electoral cycles in low er transparency countries while no such cycles can be observed in high er transparency countries furthermore we find in accordance with recent theory that electoral cycles are larger in politically more polarized countries

federalism and central bank independence the politics of german monetary policy 1957 92 two channels of political control allow elected politicians to influence monetary policy first political threats to the status structure or very existence of the central bank may force central bankers to comply with politically motivated demands on monetary policy second politicians may use their powers of appointment to ensure that central bank appointees share their electoral and party political goals this paper derives the monetary policy outcomes obtained as a function of the degree of central bank independence zero partial or full and central bankers types partisans or technocrats based on a case study of the 1957 and 1992 institutional changes to the german central banking system and a regression analysis covering the period in between i argue that the formal independence of the system is protected by its embeddedness in the institutions of german federalism and by the federalist components of its decentralized organizational structure the behavioral independence of the german central bank fluctuates over time with the party control of federalist veto points the bundesbank is staffed with nonpartisan technocrats who are partially insulated from political pressures

who surfs who manipulates the determinants of opportunistic election timing and electorally motivated economic intervention in this paper i develop a career concerns model of government policy choice within a dynamic optimal stopping framework to predict the degree of surfing opportunistic timing and manipulation politically motivated economic intervention under alternate institutional structures and voter characteristics among other results i find that the likelihood of opportunistic elections rises with exogenous economic performance with longer maximum term lengths with future electoral uncertainty and with economic volatility but diminishes in the value of office holding manipulation increases with the maximum term length and with the value of office holding but decreases with exogenous economic performance and with economic volatility the model suggests that single party governments should be highly opportunistic in calling elections and that countries that allow opportunistic election timing should experience less economically distortionary political intervention than their fixed timing counterparts

the institutional environment for infrastructure investment the empirical evidence that links political institutions to economic outcomes has grown dramatically in recent years however virtually all of this analysis is undertaken using data from the past three decades this paper extends this empirical framework by performing a two century long historical analysis of the determinants of infrastructure investment in a panel of over 100 countries the results demonstrate that political environments that limit the feasibility of policy change are an important determinant of investment in infrastructure copyright 2002 oxford university press

the duality of collaboration inducements and opportunities in the formation of interfirm linkages i argue that the linkage formation propensity of firms is explained by simultaneously examining both inducement and opportunity factors drawing upon resource based and social network theory literatures i identify three forms of accumulated capital technical commercial and social that can affect a firm s inducements and opportunities to form linkages firms possessing these capital stocks enjoy advantages in linkages formation however firms lacking these accumulated resources can still form linkages if they generate a radical technological breakthrough thus i identify paths to linkage formation for leading as well as peripheral firms i test these arguments with longitudinal data on technical collaborative linkages in the global chemicals industry copyright 2000 john wiley sons ltd

seeing the forest through the trees a meta analysis of political budget cycles despite a vast number of articles the political budget cycle literature contains many conflicting theories and empirical results i conduct the first ever meta analysis of this literature in order to establish whether a link between elections and government budgets exists using data on 1198 estimates across 88 studies published between 2000 and 2015 i find evidence of a statistically significant yet substantively small increase in government expenditures and public debt around elections and reductions in revenues and fiscal balance using meta regression analysis combined with bayesian model averaging i find support for some of the context conditional theories in the literature although the findings of political budget cycles are robust to publication bias as well as some of the methodological and study specific choices authors are forced to make they also shed light on how certain decisions may affect a study s findings this has implications for current and future research on political budget cycles

r d subsidies external collaborative breadth differential gains and the role of collaboration experience abstract external collaboration breadth is important for firms to acquire the knowledge needed to innovate in this paper we combine cross sectional and longitudinal data from the spanish panel of technological innovation survey pitec to examine the indirect impact of r d subsidies on firm external collaboration breadth we contribute to understanding of the indirect impacts of r d subsidies by first providing strong evidence of an economically significant average positive impact of r d subsidies on firm external collaboration breadth second our results advance understanding of the differential impacts of r d subsidies by revealing the vast heterogeneity of the impact at the firm level where approximately only half of treated firms experience a positive collaboration impact from r d subsidies while the remainder experience no impact or a negative effect finally we advance understanding of the characteristics explaining the differential impact of r d subsidies on external collaboration breadth by utilising the organisational learning literature to demonstrate the important role of firm collaboration experience

the performance of corporate alliances evidence from oil and gas drilling in the gulf of mexico abstract i use data on oil and gas drilling in the gulf of mexico to measure how a corporate alliance a group of firms that jointly develops an offshore tract performs relative to a solo firm i employ a regression discontinuity strategy based on bids in first price sealed bid auctions for the rights to develop leases by focusing on leases where one organizational form narrowly outbids the other i measure drilling outcomes while controlling for the endogenous matching of projects and organizational forms solo firm leases are less profitable than alliance leases because alliance members combine their information and expertise

networks and innovation in a modular system lessons from the microcomputer and stereo component industries in this paper we examine theoretically and through case studies the phenomenon of the modular system which we distinguish from a product conceived of as a prepackaged entity or appliance we argue that such systems offer benefits on both the demand side and the supply side supply side benefits include the potential for autonomous innovation which is driven by the division of labor and provides the opportunity for rapid trial and error learning demand side benefits include the ability to fine tune the product to consumer needs and therefore blanket the product space more completely both of our case studies suggest that innovation in a modular system can lead to vertical and horizontal disintegration as firms can often best appropriate the rents of innovation by opening their technology to an outside network of competing and cooperating firms we conclude by speculating on the increased importance of modular systems in the future since flexible manufacturing and rising incomes are likely to increase the driving requisites of modular systems low economies of scale in assembly and sophisticated consumer tastes

spatial proximity and firm survival in a declining industrial district the case of knitwear firms in baden wu rttemberg the literature on small firm networks in industrial districts postulates the importance of territorial proximity for business innovation and regional development but empirical research to test this proposition is sparse while there is some research on the extent of interfirm co operation little is known about the performance outcomes of co operation i develop competing hypotheses from institutional ecological and random action theories concerning the survival chances of firms located in geographic proximity and test them with data on the complete population of knitwear firms in baden wurttemberg germany for the period from 1960 to 1998 proportional hazard estimates show that location in clusters of firms in the same industry increased business failure rates and location in diversified clusters of firms operating in complementary industries reduced failure rates the empirical results are most consistent with the ecological model of localized competition in resource environments la documentation

survival of businesses using collaborative relationships to commercialize complex goods authors with many theoretical and managerial perspectives argue that businesses commercializing technologically complex goods benefit when they collaborate closely with other businesses collaboration is viewed as a means for businesses to overcome competency limitations and to achieve the close configuration of components required for complex goods we predict that collaborative relationships often assist businesses to produce complex goods but that the relationships might also cause problems for the collaborating businesses we find that firms using development oriented and marketing oriented collaborative relationships in the hospital software systems industry are less likely to shut down than businesses that follow independent approaches when the environment changes gradually but businesses using collaborative relationships are sometimes susceptible to being acquired by other firms following a sudden environmental shock businesses with collaborative relationships for activities central to the shock became more likely to shut down while businesses with collaborative relationships for activities outside the focus of the shock became more likely to survive the study critically evaluates and tests the widely stated but little tested argument that interfirm collaboration is usually beneficial the results address the issue of whether organizational choices affect comparative business performance

opportunistic political cycles test in a young democracy setting this paper tests the theory of opportunistic cycles in a decade old democracy russia finds strong evidence of cycles and provides an explanation for why previous literature often found weaker evidence using regional monthly panel data we find that 1 the budget cycle is sizable and short lived public spending shifts toward direct monetary transfers to voters 2 the magnitude of the cycle decreases with democracy government transparency media freedom voter awareness and over time and 3 preelectoral manipulation increases incumbents chances for reelection the short length of the cycle explains underestimation of its size by previous literature because of low frequency data used in previous studies

death of the lethargic effects of expansion into new technical subfields on performance in a firm s base business this paper finds that industry incumbents that do not expand into new technical subfields tend to fare poorly in their established businesses even if the market for the established products continues to exist firms that expand from their established businesses survive longer and achieve greater subsequent market share than competitors that do not expand by some measures however a failed attempt to expand into a new subfield may be even more harmful to a base business than nonexpansion the study employs conventional and accelerated event time regression models to analyze market share and survival the sample which includes 371 incumbents in four base subfields of the medical diagnostic imaging industry between 1953 and 1989 examines performance following the emergence of five new technical subfields of the industry

the underemphasized role of established firms as the sources of major innovations we argue that established firms including industry incumbents and diversifying entrants play vital all underemphasized roles as the sources of major innovations in many industries the study presents empirical evidence showing that established firms are often sources of major innovations in the telecommunications and medical sectors we conduct an exploratory investigation of how variation in the types of technical and market change influence whether industry incumbents diversifying entrants or nets companies are the sources of major innovations copyright 1996 by oxford university press

making rules credible divided government and political budget cycles political budget cycles pbcs can result from the credibility problems office motivated incumbents face under asymmetric information due to the temptation to manipulate fiscal policy to increase their electoral chances we analyze the role of rules that limit public debt because borrowing is a necessary condition for aggregate pbcs since the legislature must typically authorize new debt divided government can make these fiscal rules credible commitment is undermined by either unified government or imperfect compliance with the budget law which can help explain why pbcs are stronger in developing countries and in new democracies when divided government affects efficiency voters must trade off electoral distortions and government competence
