the effectiveness of keynes tobin transaction taxes when heterogeneous agents can trade in different markets a behavioral finance approach abstract we develop a model in which boundedly rational agents apply technical and fundamental analysis to identify trading signals in two different speculative markets whether an agent trades and if so in which market with which strategy depends on profit considerations as it turns out an ongoing evolutionary competition between the trading strategies causes complex price dynamics which closely resembles the behavior of actual speculative prices moreover we find that if the agents have to pay a transaction tax in one market price variability decreases in this market but increases in the other market however the imposition of a uniform tax on all transactions stabilizes both markets our results suggest that if regulators of a market introduce a transaction tax other markets are likely to follow

efficient mechanisms for bilateral trading we consider bargaining problems between one buyer and one seller for a single object the seller s valuation and the buyer s valuation for the object are assumed to be independent random variables and each individual s valuation is unknown to the other we characterize the set of allocation mechanisms that are bayesian incentive compatible and individually rational and show the general impossibility of ex post efficient mechanisms without outside subsidies for a wide class of problems we show how to compute mechanisms that maximize expected total gains from trade and mechanisms that can maximize a broker s expected profit journal of economic literature classification number 026

economic shocks wealth and welfare the immediate effects of the asian crisis on the well being of indonesians are examined using the indonesia family life survey an on going longitudinal household survey there is tremendous diversity in the effect of the shock for some households it was devastating for others it brought new opportunities a wide array of mechanisms were adopted in response to the crisis households combined to more fully exploit benefits of scale economies in consumption labor supply increased even as real wages collapsed households reduced spending on semi durables while maintaining expenditures on foods rural households used wealth particularly gold to smooth consumption

do r d tax credits work evidence from a panel of countries 1979 1997 this paper examines the impact of fiscal incentives on the level of r d investment an econometric model of r d investment is estimated using a new panel of data on tax changes and r d spending in nine oecd countries over a 19 year period 1979 1997 we find evidence that tax incentives are effective in increasing r d intensity this is true even after allowing for permanent country specific characteristics world macro shocks and other policy influences we estimate that a 10 fall in the cost of r d stimulates just over a 1 rise in the level of r d in the short run and just under a 10 rise in r d in the long run

property rights and efficiency of voluntary bargaining under asymmetric information we show that in public good problems under asymmetric information the success of voluntary bargaining is closely related to the structure of property rights we characterize property rights structures and mediated bargaining procedures that either lead to an efficient voluntary resolution to public good problems or achieve the efficient outcome but slightly coerce the agents into participation in this respect we identify efficient property rights structures in this paper we show that in public good problems under asymmetric information the success of any voluntary bargaining procedure is closely related to the structure of property rights in the economy for clarity of exposition we focus our attention on the following example in a town inhabited by n residents a firm is considering whether to operate a factory that generates pollution as an inevitable by product a higher level of production generates a correspondingly higher level of pollution the firm s profits are increasing with the level of production and the welfare of the residents is decreasing with the level of pollution the firm s profitability and residents preferences are assumed to be private information the structure of property rights specifies the level of pollution that the firm is entitled to emit into the environment for every such economy we describe and prove the existence of efficient property rights structures we characterize property rights structures and voluntary mediated bargaining procedures that maximize the sum of residents utilities and the firm s profit and thus lead to an efficient resolution to the public good problem furthermore we show that these efficient property rights structures are robust to changes in the underlying environment this suggests that the combination of efficiency minded legislation that would set the initial structure of property rights appropriately and a mediator who would base his recommendations on an efficient decision mechanism could facilitate the achievement of the efficient outcome under some circumstances however we show that the mediated voluntary bargaining procedure has to be replaced by compulsory arbitration that coerces agents into agreement we provide results that show that when the efficient property rights structure is adopted the degree of coercion that is necessary to obtain the efficient outcome is small thus in contrast to rob 1989 and mailath and postlewaite 1 our results apply to any public good problem where the costs and benefits of providing the public good are monotonically increasing in the level of provision and where some additional restrictions to be specified later are imposed on the form of the utility and profit functions and on the information structure

simple contracts renegotiation under asymmetric information and the hold up problem abstract in this article it is demonstrated that voluntary bargaining over a collective decision under asymmetric information may well lead to ex post efficiency if the default decision is non trivial it is argued that the default decision may be interpreted as a simple contract that the parties have written ex ante this result is used in order to show that simple unconditional contracts which are renegotiated may allow the hold up problem to be solved even if the parties valuations are private information

a mechanism design approach to climate change agreements we take a mechanism design perspective to investigate how environmental agreements should account for multilateral externalities incentive compatibility and voluntary participation by sovereign countries the optimal mechanism involves a tradeoff between a free rider problem in the effort provision of participating countries and the necessity of inducing countries to ratify the agreement this mechanism can be approximated by a simple menu with attractive implementation and robustness properties limits on enforcement and commitment might nevertheless hinder the performance of this menu making the business as usual scenario more likely

pollution claim settlements under private information abstract the classical problem of resolving a nuisance dispute between a pollution generating firm and nearby residents is modelled here as a mechanism design problem we assume that the designer of the mechanism is the firm that it is uncertain about the actual losses suffered by residents and that the initial assignment of property rights is one where each resident is entitled to prevail we derive a profitmaximizing scheme under the individual rationality and incentive compatibility constraints and examine its properties it is shown that the outcomes it yields are sometimes inefficient moreover when many residents are affected by pollution and the degree of uncertainty with respect to the losses they suffer is large these inefficiencies become rampant

public goods with congestion abstract i consider the problem of the efficient provision of a congested limited capacity public good in a setting with asymmetric information i show in particular that when the capacity of the good is limited in a wide class of economies it is possible to construct an incentive compatible mechanism that always produces the good at the efficient level balances the budget and satisfies voluntary participation constraints this result is in contrast with the corresponding impossibility result for pure public goods due to mailath and postlewaite rev econ stud 57 1990 351 359 and rob j econ theory 47 1989 307 333

risk sharing networks and insurance against illness most risk sharing tests on developing country data are conducted at the level of the village generally the full risk sharing hypothesis is rejected this paper uses detailed data on all insurance networks within a village in tanzania networks are not clustered but largely overlapping we test whether full risk sharing occurs within these networks while village level full insurance cannot be rejected for food consumption we find evidence consistent with at least partial insurance of non food consumption via networks

stage dependent intellectual property rights inspired by the chinese experience we develop a schumpeterian growth model of distance to frontier in which economic growth in the developing country is driven by domestic innovation as well as imitation and transfer of foreign technologies through foreign direct investment we show that optimal intellectual property rights ipr protection is stage dependent at an early stage of development the country implements weak ipr protection to facilitate imitation at a later stage of development the country implements strong ipr protection to encourage domestic innovation therefore the growth maximizing and welfare maximizing levels of patent strength increase as the country evolves towards the world technology frontier and this dynamic pattern is consistent with the actual evolution of patent strength in china

measurement and mismeasurement of social indicators measurement of social indicators is not without its pitfalls however and drawing conclusions based on comparisons of national aggregates is fraught with difficulties especially when data sources are sketchy the paper in that issue make a compelling argument for investing in improving the quality and frequency of data collection efforts however even when good survey data do exist serious and often quite subtle issues of comparability and measurmenet still abound this abstract was borrowed from another version of this item

an incomplete contract perspective on public good provision abstract this paper surveys what can be learned from recent advances in the incomplete contract literature to understand how public goods are or should be provided the paper starts with a section on the full information case that presents and discusses the classical samuelson condition on the optimal provision of public goods the rest of the paper presents results under asymmetric information it is constituted of two main parts in the first one the social planner has complete contracting ability we discuss the basic setting and assumptions of this comprehensive contracting approach and study the trade offs it generates the second part of the paper is devoted to the study of contracting incompleteness such incompleteness can emerge from various sources which we present and discuss we then study the case of a politically chosen decision maker and the consequences of its inability to commit for more than one period and of the ability for individuals to form groups finally we address the problem of the choice between public and private forms of public good provision the concluding section summarizes the main policy lessons

property rights and the efficiency of bargaining we show that efficient bargaining is impossible for a wide class of economic settings and property rights these settings are characterized by i the existence of adverse efficient opt out types whose participation does not change the efficient allocation and who when they opt out are the worst type other agents can face and ii non existence of the marginal core and its multivaluedness with a positive probability we also examine the optimal allocation of property rights within a given class that satisfies i such as simple property rights liability rules and dual chooser rules we characterize property rights that minimize the expected subsidy required to implement efficiency with two agents simple property rights that are optimal in this way maximize the expected surplus at the status quo allocation but this no longer holds with more agents we also study second best budget balanced bargaining under a liability rule the optimal second best liability rule may differ from but is often close to the expectation of the victim s harm which would be optimal if there were no bargaining however liability rules that are close to a simple property right result in a lower expected surplus than the simple property right they are near

r d and internal finance a panel study of small firms in high tech industries since joseph schumpeter economists have argued that internal finance should be an important determinant of r d expenditures yet almost without exception previous empirical studies have not found evidence of such a relation using newly available data the authors investigate this puzzle with a panel of 179 small firms in high tech industries under each estimation strategy they employ the authors find an economically large and statistically significant relationship between r d investment and internal finance their results are consistent with the view that because of capital market imperfections the flow of internal finance is the principal determinant of the rate at which small high tech firms acquire technology through r d copyright 1994 by mit press

household consumption smoothing through ethnic ties evidence from cote d ivoire abstract this paper investigates the hypothesis that households in cote d ivoire take part in spatially diversified risk sharing arrangements with members of their own ethnic group empirical tests are presented using several estimation methods to deal with heteroscedasticity measurement error and extreme value problems to examine whether results are robust across estimation procedures the hypothesis of complete risk sharing within ethnic groups is rejected however there appears to be some partial insurance performed by individual households with other members of the same ethnic group particularly for the households residing in the regions least likely to have access to formal financial arrangements

adult mortality and consumption growth in the age of hiv aids the authors use a 13 year panel of individuals in tanzania to assess how adult mortality shocks affect both short and long run consumption growth of surviving household members using unique data which tracks individuals from 1991 to 2004 they examine consumption growth controlling for a set of initial community household and individual characteristics the effect is identified using the sample of households in 2004 which grew out of baseline households the authors find robust evidence that an affected household will see consumption drop 7 percent within the first five years after the adult death with high growth in the sample over this time period this creates a 19 percentage point growth gap with the average household there is some evidence of persistent effects of these shocks for up to 13 years but these effects are imprecisely estimated and not significantly different from zero the impact of female adult death is found to be particularly severe

household survey data from developing countries progress and prospects assessing the adequacy of household surveys from developing countries can only be done with reference to the purpose s the data are meant to serve we assume that the objective of data collection is to support analysis of a wide range of issues concerning household welfare and behavior especially the prevalence causes and effects of poverty in its multiple dimensions analyses that address these issues can be arrayed in two dimensions methodological complexity which ranges from simple crosstabulations to sophisticated econometric techniques and specificity of the contribution to knowledge which ranges from analysis that addresses a specific policy decision in a particular country to general contributions to knowledge on economic development or research methods a few examples illustrate this typology descriptive statistics on participation in a government program by consumption quintile region or year are methodologically simple and country policy specific compilation of such work across many countries to obtain stylized facts is also methodologically simple but contributes to general knowledge of development using a specific model of household behavior to estimate the impact of charging higher prices for publicly provided services in a particular country is methodologically complex yet countryand policy specific rigorous econometric tests of alternative models of household behavior are methodologically complex and contribute to general knowledge beyond application of the method to a particular data set we discuss the adequacy of household survey data with respect to seven criteria for some criteria the threshold for adequacy varies within the two dimensional methodologyspecificity space

income smoothing and consumption smoothing one way that risk averse households protect consumption levels is to borrow and use insurance mechanisms another way common in low income economies is to diversify economic activities and make conservative production and employment choices households thus tend toward limiting exposure only to shocks that can be handled with available credit and insurance typically both types of mechanisms are studied independently but much more can be learned by studying them together first we obtain a more complete picture of risks costs and insurance possibilities second it opens the way to considering biases in standard tests of credit and insurance

consumption insurance an evaluation of risk bearing systems in low income economies the hypothesis of full risk sharing can be taken to data from low income countries and evaluate formal and informal financial systems in many contexts idiosyncratic risks are high so credit insurance arrangements could be beneficial statistical tests reveal that households in southern india take advantage of these possibilities villages in cote d ivoire and countries in thailand do not do as well the paper includes an empirical description of the devices used to smooth consumption and a theoretical discussion of private information and incentives on ideal operating systems the full information and mechanism design frameworks provide benchmarks for policy analysis

the 2007 nobel memorial prize in mechanism design theory this paper provides an overview of mechanism design theory and explains the roles played by leonid hurwicz eric maskin and roger myerson in the development of this field

the nature and importance of economic competence this chapter takes on three tasks 1 to survey the study of economic competence as it appears in economic literature 2 to give a meaningful and operational definition of economic competence as one of the factors contributing to macroeconomic growth and 3 to suggest a methodology pursued in greater depth elsewhere to generalize and link economic competence as defined at the micro firm individual level to macroeconomic growth through simulation on the micro based macroeconomic model of the swedish economic system moses by introducing knowledge in the micro setting of firm organizational competence we arrive at a very different interpretation measured at the macro industry level from that of standard neoclassical theory

when bureaucrats meet entrepreneurs the design of effective public venture capital programmes recently public efforts to finance small high technology firms have proliferated we review the motivations for these efforts and make some preliminary observations about their design we explore the underlying challenges that the financing of young growth firms poses the ways that specialised financial intermediaries address them and the rationales for public efforts to finance these companies the final section makes a set of observations about the ways in which the structure of these efforts can most effectively complement private sector activity a frequent fault in programme design is the presumption that technological criteria can be divorced from business considerations when evaluating firms the federal government has played an active role in financing new firms particularly in high technology industries since the soviet union s launch of the sputnik satellite in recent years european and asian nations and many us states have adopted similar initiatives while these programmes precise structures have differed the efforts have been predicated on two shared assumptions i that the private sector provides insufficient capital to new firms and ii that the government either can identify investments which will ultimately yield high social and or private returns or can encourage financial intermediaries to do so in contrast to other government interventions designed to boost economic growth such as privatisation programmes these claims have received little scrutiny by economists the neglect of these questions is unfortunate while the sums of money involved are modest relative to public expenditures on defence procurement or retiree benefits these programmes are very substantial when compared to contemporaneous private investments in new firms government programmes in this arena have been divided between those efforts that directly fund entrepreneurial firms and those that encourage or subsidise the development of outside investors in this paper i will focus on public venture capital initiatives programmes that make equity or equity like investments in young firms or encourage other intermediaries to make such investments in some such programmes such as the advanced technology program and the small business innovation research programmes discussed below the funds are provided as a contract or outright grant while these efforts have proliferated a consensus as to how to structure these programmes remains elusive while the design of regulatory agencies has been extensively studied from a theoretical and empirical perspective little work has

consumption smoothing and hiv aids the case of two communities in south africa abstract hiv aids threatens to overstretch the already frail informal safety nets in countries heavily affected by the epidemic potentially making it difficult for households with hiv positive members to keep up appropriate consumption levels when experiencing shocks these households may in addition face exclusion from informal insurance networks because of widespread stigmatization surprisingly the resilience of informal networks to hiv related shocks and their uncertain worth for afflicted households in particular have not been empirically tested to date using 3 years of a novel panel data set from two poor south african communities experiencing hiv related illnesses and deaths we investigate the ability of households to insure their consumption we find little evidence that affected households show an extra propensity to consume out of income changes which indicates that these households can rely on informal insurance to the same degree as their nonaffected peers however on the basis of the

is consumption insured against illness evidence on vulnerability of households to health shocks in rural ethiopia abstract low and volatile incomes and absence of well developed financial markets make consumption smoothing an important issue in low income countries based on the theory of full insurance and using 2 years of panel data this study examines the impact of illness on the consumption of rural households and the capacity of existing risk sharing mechanisms in insuring consumption against health shocks in the rural areas of ethiopia the results show that illness has a statistically significant negative impact on the stability of consumption and the capacity of households or existing intra and interhousehold risk sharing arrangements in insuring consumption against illness varies across different consumption items the regression results show that the hypothesis of consumption insurance cannot be rejected in the case of total food consumption implying that basic items that come from own production and from external sources gifts are better insured and insensitive to the illness of the head however the

risk and insurance in village india comment the protection of poor households in high risk agrarian economies from shocks to their incomes has often been seen as a compelling motive for various forms of policy intervention including transfers of cash or food credit subsidies and public employment schemes for a survey see lipton and ravallion 1995 the desirability of such safety net policies clearly depends on how well pre existing risk sharing arrangements work while it is commonly thought that without effective policy intervention rural households are vulnerable to village wide shocks such as adverse prices or poor rains it is less clear to what extent risk sharing institutions within the village mitigate the effects of idiosyncratic income risk stemming for instance from ill health or localized crop damage 2 several recent papers have used household level data to implement tests of risk sharing that might inform such concerns 3 these tests are based on the proposition that with perfect risk sharing consumption at the household level should be insured against idiosyncratic risks and thus depend solely on the realization of the aggregate risk wilson 1968 diamond 1967 townsend 1994 tests this implication of perfect intra village risk sharing using longitudinal household data on consumptions and incomes for three villages in india he reports that the full insurance hypothesis provides a surprisingly good benchmark in that household consumptions co move and do not appear to be much influenced by contemporaneous own income our aim here is to examine the robustness of this potentially important finding we have two main concerns the first is that the specification townsend adopts potentially biases his test towards the null hypothesis of full insurance because it yields inconsistent estimates of the key test parameter under a plausible alternative we therefore estimate a different specification that generates consistent estimates under both the null and the alternative our second concern is that a particular form of measurement error in the consumption data townsend uses may have further biased his results toward the null hypothesis of full insurance to address this concern we use an instrumental variables procedure when we implement the test of consumption insurance with townsend s consumption data we also re estimate the test equations with a measure of consumption derived from the same underlying primary data by an alternate method finally townsend reports 1discussions with robert townsend stimulated our interest in this investigation the staff of the

partnership dissolution with interdependent values we study partnership dissolution when valuations are interdependent and only one party is informed in contrast with the case of private values cramton gibbons and klemperer 1987 in which efficient trade is feasible whenever initial shares are about equal there exists a wide class of situations in which full efficiency cannot be reached in these cases i the subsidy required to restore the first best is minimal when the entire ownership is allocated initially to one of the parties and ii ruling out external subsidies the second best welfare is maximized when one of the parties initially has full ownership

full insurance in the presence of aggregate uncertainty this paper tests implications of full consumption insurance the object is to determine how much mileage can be obtained from a model with complete markets with such features as private information or liquidity constraints omitted the implication exploited is that individual consumption responds to aggregate risk but not to idiosyncratic risk the test involves regressing the change in household consumption onto the change in aggregate consumption and other right hand side variables such as the change in household income and change in employment status all variables other than the change in aggregate consumption are predicted to be insignificant in explaining the change in household consumption with observations on consumption and income for 10 695 households from the consumer expenditure survey the results are mixed the results for one specification exponential utility are mostly consistent with full consumption insurance the results for the other specification power utility are not

do tax credits stimulate r d spending the effect of the r d tax credit in its first decade abstract this paper examines the impact of the u s federal r d tax credit between 1981 1991 using confidential irs data from corporate tax returns the empirical analysis makes two key advances on previous work first it implements a new instrumental variables iv strategy based on tax changes that directly addresses the simultaneity of r d spending and marginal credit rates second the analysis makes use of new restricted access irs corporate return data describing r d expenditures estimates imply that a10 reduction in the user cost of r d leads the average firm to increase its research intensity the ratio of r d spending to sales by 19 8 in the short run long run estimates imply that the average firm faces adjustment costs and increases spending over time though small and young firms show evidence of reversing initial increases analysis of the components of qualified research shows that wages and supplies account for the bulk of the increase in research spending elasticities of qualified and total research intensities from a smaller sample suggest firms respond to user cost changes largely by increasing their qualified spending meaning that the type of r d the federal credit deems qualified research is an important margin on which the credit affects firm behavior

measurement error in recall surveys and the relationship between household size and food demand variation in household survey design and implementation is used to obtain evidence of nonrandom measurement error in recall surveys of household expenditure these surveys which are used especially in developing countries appear to have measurement errors in food expenditures and in food budget shares that are correlated with household size these correlated errors may be part of the explanation for a puzzling pattern of falling food demand with rising household size in poorer countries

the effectiveness of r d tax credits in order to measure the effect of tax credits on private r d investment researchers confront the difficult problem of finding an exogenous measure of tax policy that exhibits sufficient variation

a simple test of consumption insurance are consumers effectively insured against idiosyncratic shocks to income or wealth either by formal institutions such as charities private insurance and government programs or by informal mechanisms such as gifts and loans from relatives friends and neighbors under full insurance consumption growth should be cross sectionally independent of idiosyncratic variables that are exogenous to consumers this proposition is tested by cross sectional regressions of consumption growth on a variety of exogenous variables full insurance is rejected for long illness and involuntary job loss but not for spells of unemployment loss of work due to strike and an involuntary move

vulnerability seasonality and poverty in ethiopia most studies examining the dynamics of welfare have found large fluctuations in consumption over relatively short periods suggesting substantial short run movements in and out of poverty the consequence is that cross section poverty research may not be able to identify the poor in this study we explore this short run variability further we use a data set on a panel of 1450 households in different communities in rural ethiopia surveyed thrice over 18 months on average year to year poverty is very similar however we find high variability in consumption and poverty over the seasons and year by year econometric analysis suggests that consumption is affected by idiosyncratic and common shocks including rainfall and household specific crop failure while households respond to seasonal incentives related to changing labour demand and prices the results imply that a larger number of households are vulnerable to shocks than implied by the standard poverty statistics while some of the non poor in the

growth dynamics in the biomedical biotechnology system this article aims to understand the dynamics of growth in the biomedical biotechnology system that consists of a variety of actors ranging from universities medical supplies firms and drug research firms to clinical service suppliers based on a comparative study made in ohio and in sweden we have analyzed three main factors technology competencies technology transfer and networking capabilities our findings show a set of differences that can be grouped into two categories viz management and agglomeration externalities differences in management appear at three points the resources allocated to technological competence development managerial skills in the technology transfer phase and the use of technology councils ohio seems to offer a better environment for starting up new firms and enabling these firms to successfully commercialize their technological assets the agglomeration externalities that make a difference between the two regions might be grouped into two categories increasing returns arising from network externalities and the advantages of networking with a variety of supporting organizations in the system

asymmetric information bargaining problems with many agents a yes or no decision must be made about some issue all agents must agree the coase theorem asserts that the efficient outcome will always result suppose the value positive or negative that an individual attaches to an affirmative decision is privately known to that individual it is proved under very mild conditions that with independent types as the number of agents increases the probability of an affirmative efficient decision goes to zero an example in which it is common knowledge that an affirmative decision is efficient and yet the probability of such a decision goes to zero is given

beggar thy neighbor the in state out of state and aggregate effects of r d tax credits abstract the proliferation of r d tax incentives among u s states in recent decades raises two questions i are these tax incentives effective in increasing in state r d ii how much of any increase is due to r d being drawn away from other states this paper answers i yes and ii nearly all the paper estimates an augmented r d factor demand model using state panel data from 1981 to 2004 i estimate that the long run elasticity of in state r d with respect to the in state user cost is about 2 5 while its elasticity with respect to out of state user costs is about 2 5 suggesting a zero sum game among states

investment cash flow sensitivities are useful a comment on kaplan and zingales arecent paper in this journal by kaplan and zingales reexamines a subset of erms from work of fazzari hubbard and petersen and criticizes the usefulness of investment cash eow sensitivities for detecting enancing constraints we show that the kaplan and zingales theoretical model fails to capture the approach employed in the literature and thus does not provide an effective critique moreover we describe why their empirical classiecation system is eawed in identifying both whether erms are constrained and the relative degree of constraints across erm groups we conclude that their results do not support their conclusions about the usefulness of investment cash eow sensitivities in a recent paper in this journal kaplan and zingales 1997 hereinafter kz argue that investment cash eow sensitivities do not provide useful evidence about the presence of enancing constraints because kz use a subset of the same erms and the same regressions as fazzari hubbard and petersen 1988 hereinafter fhp and claim page 176 that fhp can legitimately be considered the parent of all papers in this literature it is appropriate that we respond based on a simple theoretical model kz reach the provocative conclusion page 211 that the investment cash eow sensitivity criterion as a measure of enancial constraints is not well grounded in theory in section i we show that the kz model does not capture the theoretical approach employed in fhp and many subsequent studies most of the kz paper attempts to show that empirical investment cash eow sensitivities do not increase monotonically with the degree of enancing constraints within the 49 low dividend erms from the fhp sample in section ii we explain why the kz classiecation of the degree of constraints is eawed in identifying both whether or not erms are constrained absolute constraints as well as the relative degree of constraints across erms as a result we argue in section iii that there is no expected ex ante pattern for the

interest rates r d investment and the distortionary effects of r d incentives abstract this paper conducts the first analysis of how interest rates are related to firms allocation of investment between r d and non r d activities and how r d incentives alter this relationship it theoretically predicts that if firms receive incentives mostly in the form of grants and subsidies that reduce their dependence on external finance their share of r d spending increases decreases during a credit tightening easing conversely if tax credits are the primary incentive firms decrease increase their share of r d spending during a credit tightening easing the paper demonstrates empirical support for these predictions by using firm level financial and sector level r d incentives data and a unique methodology that focuses on the within firm allocation of investment

reinventing strategies for emerging markets beyond the transnational model with established markets becoming saturated multinational corporations mncs have turned increasingly to emerging markets ems in the developing world such em strategies have been targeted almost exclusively at the wealthy elite at the top of the economic pyramid recently however a number of mncs have launched new initiatives that explore the untapped market potential at the base of the economic pyramid the largest and fastest growing segment of the world s population reaching the four billion people in these markets poses both tremendous opportunities and unique challenges to mncs as conventional wisdom about mnc global capabilities and subsidiary strategy in ems may not be appropriate how mncs can successfully enter these low income markets has not been effectively addressed in the literatures on global and em strategies an exploratory analysis involving interviews with mnc managers original case studies and archival material indicates that the transnational model of national responsiveness global efficiency and worldwide learning may not be sufficient results suggest that the success of initiatives targeting low income markets is enhanced by recognizing that western style patterns of economic development may not occur in these business environments business strategies that rely on leveraging the strengths of the existing market environment outperform those that focus on overcoming weaknesses these strategies include developing relationships with non traditional partners co inventing custom solutions and building local capacity together these successful strategies suggest the importance of mncs developing a global capability in social embeddedness

public good provision with many participants for a nonexcludable public good with benefit and cost functions independent of the number of participants this paper studies second best allocations under bayesian interim incentive compatibility and interim individual rationality as the number of participants becomes large second best provision levels converge in distribution to first best levels if the latter are bounded second best provision levels become large in absolute terms but small relative to first best levels if benefit and cost functions are isoelastic in contrast for an excludable public good the ratio of second best to first best levels is bounded away from zero
