managing the protection of innovations in knowledge intensive business services abstract how do knowledge intensive business services kibs protect their inventions from imitation by rival firms when choosing among various protection mechanisms data from the 2003 statistics canada innovation survey on services are used to investigate this issue by looking into complementarities substitution and independence among eight protection mechanisms a multivariate probit mvp model is estimated to take into account the fact that kibs simultaneously consider many alternative intellectual property ip protection methods when they attempt to protect their innovations results show that patents registration of design patterns trademarks secrecy and lead time advantages over competitors constitute legal and informal methods that are used jointly these complementarities suggest that ip protection mechanisms that are interdependent and reinforce each other to protect innovations from imitation by rival firms constitute a pattern on which firms rely to protect their innovations from imitation a second pattern is based on the fact that kibs rely on patents and complexity of designs as substitutes and tend to use registration of design patterns and complexity of designs as substitutes in protecting their innovations from imitation a third emerging pattern concerns protection mechanisms that are independent from each other and exhibit no synergy and do not reinforce each other to protect innovations from imitation by other firms

sacrifice and stigma reducing free riding in cults communes and other collectives this paper presents an economic analysis of religious behavior that accounts for the continuing success of groups with strange requirements and seemingly inefficient prohibitions the analysis does not presuppose any special motives for religious activity rather religion is modeled as a club good that displays positive returns to participatory crowding the analysis demonstrates that efficient religions with perfectly rational members may benefit from stigma self sacrifice and bizarre behavioral restrictions the model also addresses sacrifice in nonreligious social clubs fraternities communes political parties work groups and families

complementarity and external linkages the strategies of the large firms in biotechnology in biotechnology large firms enter into different kinds of linkages with universities and small medium sized research intensive firms we test the hypothesis that the strategies of external linkage of the large firms with other parties are complementary to one another we show that if any two strategies are complementary i e undertaking more of one strategy raises the marginal value of the other then they are positively correlated using data for a sample large us european and japanese chemical and pharmaceutical producers we find that the strategies above are positively correlated even after controlling for firm specific characteristics

testing for complementarity glyphosate tolerant soybeans and conservation tillage many decisions in agriculture are made over combinations of inputs and or practices that may be complements the presence of complementarity among producer decisions can have deep implications for market outcomes and for the effectiveness of policies intended to influence them identifying complementarity relations however is a challenging pursuit drawing on recent methodological advances in this paper we propose a new test for complementarity between glyphosate tolerant soybeans and conservation tillage that overcomes limitations of previous studies specifically we develop a structural discrete choice framework of joint soybean tillage adoption that explicitly models both complementarity and unobserved heterogeneity the model is estimated with a large dataset of farm level choices that spans the 1998 2011 period and contains repeated observations for many of the sampled individuals we find that glyphosate tolerant soybeans and conservation tillage are indeed complementary practices a conclusion supported by several robustness checks in addition our estimation shows that farm operation scale promotes the adoption of both conservation tillage and glyphosate tolerant seed and that all of higher fuel prices more droughty conditions and soil erodibility increase use of conservation tillage we also apply our results to simulate annual adoption rates for conservation tillage in a scenario without glyphosate tolerant soybeans available as a choice we find that the adoption of conservation tillage has been about ten percent higher due to the advent of glyphosate tolerant soybeans

innovation complementarity and environmental productivity effects reality or delusion evidence from the eu abstract innovation is a key element behind the achievement of desired environmental and economic performances regarding co2 mitigation strategies would require cuts in emissions of around 80 90 with respect to 1990 by 2050 in the eu we investigate whether complementarity namely integration between the adoption of environmental innovation measures and other technological and organizational innovations is a factor that has supported reduction in co2 emissions per value added that is environmental productivity we merge new eu innovation and wiod data to assess the innovation effects on sector co2 performances at a wide eu level we find that jointly adopting different innovations is not a widespread factor behind increases in environmental productivity nevertheless even though complementarity is not a low hanging fruit a case where innovation complementarity arises is for manufacturing sectors that integrate eco innovations with product innovations one example of this integrated action is a strategy that pursues energy efficiency with product value enhancement we believe that the lack of integrated innovation adoption behind environmental productivity performance is a signal of the current weaknesses economies face in tackling climate change and green economy challenges incremental rather than more radical strategies have predominated so far the latter have been confined to industrial niches in terms of the number of involved firms this is probably insufficient when we look at long term economic and environmental goals

complementarities in organizational design and the diffusion of information technologies an empirical analysis we use a specially designed survey on french firms located in haute savoie to provide empirical evidence suggesting that information and communication technologies adoption is not only influenced by the traditional factors of technology diffusion but also by complementarity effects between strategies organization and information technologies the data collected permitted several advances firstly we could study authentic ict while the recent literature has mainly focused on computer capital stocks or automation tools secondly we constructed measures of the determinants put forward by the models of technology diffusion thirdly we studied three kinds of practices organizational and strategic practices technological choices

animal health inputs endogenous risk general infrastructure technology adoption and industrialized animal agriculture abstract this paper develops a microeconomic model of concentrated animal feeding operations that admits roles for all of animal health inputs genetic profile choices and the pertaining economic infrastructure the basic model emphasizes how time on feed feed density and biosecurity choices interact as well as how these choices respond to i input prices and ii attributes regarding animal productivity parameters that might be influenced by policy choices such as animal welfare strictures and restraints on use of medication we show that ostensibly substituting inputs in protecting against animal health risks may in fact be complements and that the model s production choices come as a complementary package we then extend the model to endogenize the choice of animal genetics a finding is that innovations in general infrastructure encourage herd owners to choose more feed efficient but less hardy animals higher feed conversion efficiency then induces the use of denser feed rations accelerated finishing and greater levels of biosecurity actions at farm perimeters our theory provides a coherent framework for explaining associations among inputs and outcomes that are linked with confined animal agriculture it also explains how animal protein supply chain technology adoption and performance can differ according to a region s state of infrastructure why responses to a change in infrastructure may be large and why public sector efforts to reduce production risk may beget private sector effort to do so

social status and economic performance a survey abstract this survey combines ideas and results from sociology and economics recognizing that economic decisions are often shaped by social concerns and influences based on the sociological literature we define social status and describe its measurement we then describe the role of social status in economic analysis of saving and consumption wages and economic growth we review recent work on status determination in equilibrium including evolutionary models we conclude with some remarks on the need for further interaction between sociology and economics

a formalization and test of the religious economies model the religious economies argument maintains that religious pluralism promotes religious participation although this theory has been much debated by sociologists of religion evaluation has been hindered by the lack of a formal model this paper offers a formalization that builds on the product differentiation framework from industrial organization economics the model suggests a new measure of religious competition and a new empirical test one religious market may be regarded as more competitive than another religious market if the set of denominations present in the first contains the set of denominations present in the second given this partial order on the set of religious markets the model predicts that more competitive markets will have higher religious participation this prediction is examined for two data sets previously considered in the literature new york towns in 1865 and u s counties in 1990 although the analysis highlights an important theoretical ambiguity regarding the strategic interdependence of denominational effort choices and reports a negative empirical finding that more competitive u s counties tend to have lower religious participation the paper proceeds constructively attempting to identify viable directions for future research within the religious economies paradigm

vanity and congestion a study of reciprocal externalities this paper models a private goods oligopoly market characterized by negative and reciprocal externalities although firms compete in prices and products are undifferentiated in equilibrium the pr

an economic theory of church strictness this paper introduces spatial location models into the economics of religion we offer a new explanation for the observed tendency of state monopoly churches to locate toward the low tension end of the strictness continuum obtained through the conjunction of benevolent preferences denominations care about the aggregate utility of members and asymmetric costs of going to a more or less strict church than one prefers we derive implications regarding the relationship between religious strictness and membership religious market interactions and asymmetric costs of membership highlight new explanations for some well established stylised facts opening the way to new empirical comparisons with more traditional explanations

testing for complementarities in reduced form regressions a note abstract in many cases it is important to know whether choice variables for a decision maker are mutual complements but a structural model cannot be estimated a unified framework for testing for complementarity through reduced form regressions is provided

modeling undesirable factors in efficiency evaluation abstract data envelopment analysis dea measures the relative efficiency of decision making units dmus with multiple performance factors which are grouped into outputs and inputs once the efficient frontier is determined inefficient dmus can improve their performance to reach the efficient frontier by either increasing their current output levels or decreasing their current input levels however both desirable good and undesirable bad factors may be present for example if inefficiency exists in production processes where final products are manufactured with a production of wastes and pollutants the outputs of wastes and pollutants are undesirable and should be reduced to improve the performance using the classification invariance property we show that the standard dea model can be used to improve the performance via increasing the desirable outputs and decreasing the undesirable outputs the method can also be applied to situations when some inputs need to be increased to improve the performance the linearity and convexity of dea are preserved through our proposal

multilateral productivity comparisons when some outputs are undesirable a nonparametric approach multilateral productivity comparisons of firms producing multiple outputs some of which are undesirable are obtained by making two modifications to the standard farrell approach to efficiency measurement the restriction that production technology satisfy strong disposability of outputs is relaxed to allow for the fact that undesirable outputs may be freely disposable and the efficiency measures are modified to allow for an asymmetric treatment of desirable and undesirable outputs performance measures that satisfy these requirements are calculated as solutions to programming problems the methodology is applied to a sample of mills producing paper and pollutants

dynamic models of religious conformity and conversion theory and calibrations abstract this paper develops overlapping generations models to explain and simulate changes in the proportion of secular and religious people the church is modeled as generating an externality associated with conformity enhancing education observed changes in the number of nonbelievers are explained by different birth rates among secular and religious parents and the relative proportion of young nonconformists calibrations for the conformity rates among secular and religious people show that the observed long run increase in the difference between percentage of secular people in europe and the united states can be attributed to lower conformity rates prevailing in europe

complementarities between obstacles to innovation evidence from france abstract this paper investigates obstacles to innovation faced by french manufacturing firms using cis2 data we distinguish between obstacles in postponed projects and obstacles in abandoned projects first we highlight the most important barriers to innovation faced by firms and find that lack of skilled personnel is one of these second based on descriptive analysis correspondence analysis and multivariate probit models we explore factors explaining the perception of obstacles and study complementarities between those obstacles we show that while adopting a package of policies increases the pace of innovation a more targeted choice among policies is needed to encourage firms to persevere in their innovative efforts

price competition when consumer behavior is characterized by conformity or vanity it has long been recognized that the pleasure of consuming a good may be affected by the consumption choice of other consumers in some cases social pressures may lead to conformity in some others individuals may feel the need of exclusiveness under the form of vanity such externalities have proven to be important in several markets however the market implication of these externalities are still unclear to investigate them we propose to combine the consumption externality model and the spatial duopoly model when conformity is present but not too strong both firms remain in business but price competition is fiercer and results in lower prices the market share of the large firm increases with the population size as the population keeps rising the large firm may serve the entire market and set a price that has the nature of a limit price when conformity is strong enough different equilibria may exist in most of these equilibria a single firm captures the whole market at the other extreme when vanity is at work price competition is relaxed

how network externalities can exacerbate intergroup inequality the authors describe a common but largely unrecognized mechanism that produces and exacerbates intergroup inequality the diffusion of valuable practices with positive network externalities through social networks whose members differentially possess characteristics associated with adoption the authors examine two cases the first to explore the mechanism s implications and the second to demonstrate its utility in analyzing empirical data in the first the diffusion of internet use network effects increase adoption s benefits to associates of prior adopters an agent based model demonstrates positive monotonic relationships given externalities between homophily bias and intergroup inequality in equilibrium adoption rates in the second rural urban migration in thailand network effects reduce risk to persons whose networks include prior migrants analysis of longitudinal individual level migration data indicates that network homophily interacts with network externalities to induce divergence of

are employee selection and incentive contracts complements or substitutes there is a debate in the literature as to whether employee selection is a substitute or complement to incentive contracting we argue that incentive contracts and selection can be both complements and substitutes conditional on the contracting difficulty faced by the firm we examine these control choices in a setting where contracting difficulties arise due to the firm s choice of strategy and from the volatility created by the firm s external environment we select a firm s commitment to organizational learning ol as our strategic choice variable as this provides a useful proxy for identifying settings where explicit incentive contracting is difficult the results show that as firms become increasingly committed to ol incentive contracts and employee selection operate as complements however with a high commitment to ol and an increasing level of external volatility contracting on performance measures will become less effective in this context our results indicate that there is a substitution effect toward employee selection

in search of complementarity in innovation strategy internal r d and external knowledge acquisition empirical research on complementarity between organizational design decisions has traditionally focused on the question of existence of complementarity in this paper we take a broader approach to the issue combining a productivity and an adoption approach while including a search for contextual variables in the firms strategy that affects complementarity analysis of contextual variables is not only interesting per se but also improves the productivity test for the existence of complementarity we use our empirical methodology to analyze complementarity between innovation activities internal research and development r d and external knowledge acquisition our results suggest that internal r d and external knowledge acquisition are complementary innovation activities but that the degree of complementarity is sensitive to other elements of the firms strategic environment we identify reliance on basic r dthe importance of universities and research centers as an information source for the innovation processas an important contextual variable affecting complementarity between internal and external innovation activities

introduction to the economics of religion after a very long hiatus economists have begun again to study the relationship between economics and religion this article seeks to summarize and evaluate the principal themes and empirical findings that have appeared in some 200 recent papers on the economics of religion although some of the research concerns the economic consequences of religiosity most applies standard economic theory to the study of individual religious activity the characteristics of religious groups and the impact of regulation and competition on religious markets

which countries have state religions among 188 countries 72 had no state religion in 2000 1970 and 1900 58 had a state religion throughout and 58 had 1 or 2 transitions we use a hotelling spatial competition model to analyze the likelihood that the religion market would be monopolized similar forces influence a government s decision to establish a state religion consistent with the model the probability of state religion in 1970 and 2000 is increasing with the adherence rate to the main religion has a nonlinear relation with population and has little relation with per capita gdp the probability of state religion decreases sharply under communism but lagged communism has only a weak effect with costly adjustment for institutions the probability of state religion in 1970 or 2000 depends substantially on the status in 1900 this persistence is much stronger for countries with no major regime change than for countries with such a change

an anatomy of cartel contracts we study cartel contracts using data on 18 contract clauses of 109 legal finnish manufacturing cartels one third of the clauses relate to raising profits the others deal with instability through incentive compatibility cartel organization or external threats cartels use three main approaches to raise profits price market allocation and specialization these appear to be substitutes choosing one has implications on how cartels deal with instability simplifying we find that large cartels agree on prices cartels in homogenous goods industries allocate markets and small cartels avoid competition through specialization

veblen effects in a theory of conspicuous consumption the authors examine conditions under which veblen effects arise from the desire to achieve social status by signaling wealth through conspicuous consumption while veblen effects cannot ordinarily arise when preferences satisfy a single crossing property they may emerge when this property fails in that case budget brands are priced at marginal cost while luxury brands though not intrinsically superior are sold at higher prices to consumers seeking to advertise wealth luxury brands earn strictly positive profits under conditions that would with standard formulations of preferences yield marginal cost pricing the authors explore factors that induce veblen effects and they investigate policy implications copyright 1996 by american economic association

is environmental innovation embedded within high performance organisational changes the role of human resource management and complementarity in green business strategies abstract this paper investigates whether firms joint implementation of organisational innovation and training may foster their adoption of environmental innovation ei and if this correlation falls within porter hypothesis ph framework we study the relationship of complementarity between strategies of high performance work practices hpwp and human resource management hrm when ei adoption is the firms objective using an original dataset on 555 italian industrial firms regarding ei hpwp and hrm coherent with the last cis2006 2008 survey results show that sector specificity matter the only case in which strict complementarity is observed in organisational change concerns co 2 abatement a relatively complex type of ei but this is true only when the sample is restricted to more polluting and regulated sectors this evidence is coherent with the porter hypothesis complementarity related adoption of ei is an element of organisational change in firms that are subject to more stringent environmental regulations nevertheless the fact that strict complementarity is not a diffuse factor behind the adoption of all environmental innovation indeed does not come as a surprise at this stage in the development of green strategies the share of eco firms is still limited even in advanced countries that are seeking tools for a new competitiveness the full integration of eis within the internal capabilities and firm s own assets is far from being reached even in advanced and competitive industrial settings

complementarities in innovation policy this paper develops a framework for testing discrete complementarities in innovation policy using european data on obstacles to innovation we propose a discrete test of supermodularity in innovation policy leading to a number of inequality constraints we apply our test to two types of innovation decisions to innovate or not and if so by how much we find that the evidence regarding the existence of complementarity in innovation policies depends on the phase of innovation that is targeted getting firms innovative or increasing their innovation intensity as well as on the particular pair of policies that is being considered the two phases of the innovation process i e the probability of becoming an innovator and the intensity of innovation are subject to different constraints interestingly there seems to be a need to adopt a package of policies to make firms innovate while a more targeted choice among policies is necessary to make them more innovative

three way complementarities performance pay human resource analytics and information technology we test for three way complementarities among information technology it performance pay and human resource hr analytics practices we develop a principal agent model examining how these practices work together as an incentive system that produces a larger productivity premium when the practices are implemented in concert rather than separately we assess our model by combining fine grained data on human capital management hcm software adoption over 11 years with detailed survey data on incentive systems and hr analytics practices for 189 firms we find that the adoption of hcm software is greatest in firms that have also adopted performance pay and hr analytics practices furthermore hcm adoption is associated with a large productivity premium when it is implemented as a system of organizational incentives but has less benefit when adopted in isolation the system of three way complements produces disproportionately greater benefits than pairwise interactions highlighting the importance of including all three complements productivity increases significantly when the hcm systems go live but not when they are purchased which can be years earlier this helps rule out reverse causality as an explanation for our findings this paper was accepted by sandra slaughter information systems
