unraveling the effects of environmental outcomes and processes on financial performance a non linear approach abstract we examine the roles of the outcome and process dimensions of environmental performance in determining financial performance as measured by tobin s q outcomes refer to the impacts of the firm on the natural environment while processes are the firm s actions to reduce these outcomes we focus on a specific outcome carbon emissions and suggest that it affects tobin s q non linearly we find that firms achieve the highest financial performance when their carbon performance is neither low nor high but intermediate we also find that environmental processes moderate this relationship as they reinforce firms financial performance through improved stakeholder management this mixed picture suggests that firms do not generally internalize the costs of poor carbon performance but those that stand out in both environmental outcomes and processes achieve net financial benefits these findings are based on a sample of carbon intensive firms that disclosed their greenhouse gas ghg emissions through the carbon disclosure project from 2007 through 2013

workfare wellbeing and consumption evidence from a field experiment with kenya s urban poor abstract restrictions like work requirements and constraints on voucher transfers are often used in social welfare systems but little empirical evidence exists on their impact on wellbeing we conducted a 10 day randomized experiment with 432 individuals living below the poverty line in the kawangware settlement of nairobi kenya testing two elements of social welfare design workfare versus welfare and restricted versus unrestricted vouchers participants were randomly assigned to a work condition involving daily work for unrestricted vouchers or one of two wait conditions involving daily waiting for vouchers that were either unrestricted or partially restricted to staple foods we find that working improved psychological wellbeing relative to waiting suggesting that the means of implementing welfare programs may have important effects on individuals beyond the impact of monetary benefit alone furthermore although the restrictions were inframarginal partially restricted vouchers crowded in spending on staple foods suggesting the existence of a flypaper effect in spending from restricted vouchers

evaluating welfare reform in the united states this paper reviews the economic literature on welfare reform over the 1990s a brief summary of the policy changes is followed by a discussion of the methodological techniques that analyze the effects of these changes on outcomes the paper then critically reviews the econometric and experimental literature on caseload changes labor force changes poverty and income changes and family formation changes a growing body of evidence suggests that recent policy changes have influenced economic behavior and well being one particular set of new style welfare programs seems to show especially promising results with significantly increased work and earnings and reduced poverty

mergers and the market for organization capital abstract in this paper mergers are an equilibrium outcome in which acquirers marry targets so as to gain access to their organization capital firms with lower learning costs about the new technology are not necessarily those that manage it best once it is mature since there are gains from trade a market for organization capital can arise through mergers this model generates a merger wave after a shock to technology and is consistent with several other stylized facts on mergers documented in the literature

is firm specific innovation associated with greater value appropriation the roles of environmental dynamism and technological diversity abstract this paper extends the resource based theory of the firm to examine the contingencies that either intensify or reduce the relationship between firm specific innovation and value appropriation based on a large scale analysis of a sample of us manufacturing firms we found that greater innovation rents appropriation is associated with an increase in firm specificity of its innovative knowledge but the positive relationship between firm specific innovations and firm value appropriation tends to decrease when the product or technology market is highly dynamic further under high environmental dynamism firms should increase the diversity in their knowledge composition in order to mitigate the risk of value erosion associated with firm specific innovations

single crossing random utility models we propose a novel model of stochastic choice the single crossing random utility model scrum this is a random utility model in which the collection of preferences satisfies the single crossing property we offer a characterization of scrums based on two easy to check properties the classic monotonicity property and a novel condition centrality the identified collection of preferences and associated probabilities is unique we show that scrums nest both single peaked and single dipped random utility models and establish a stochastic monotone comparative result for the case of scrums

intangible capital market share and corporate strategy this paper theoretically and empirically identifies the determinants of firm profitability and market share for twelve broadly defined us manufacturing industry groups the effects of advertising research and development and diversification on profitability and market share are econometrically tested for each industry group and corporate strategy implications of the results are considered one major result of the analysis is that research and development r d tends to be much more effective as a means of enhancing firm profitability than advertising and research and development spending decisions are more closely related to the profitability of r d than advertising decisions are related to the profitability of advertising

targeting assistance to the poor efficient allocation of transfers when household income is not observed abstract this paper examines the problem of how to transfer money or other forms of assistance to poor households when one observes some characteristics of households but not their incomes this and related issues are often referred to as the targeting problem the paper first sets out the problem formally as one of minimizing a poverty index given a fixed amount of money available for transfers assuming that household survey data are available which include accurate income and or expenditure information the solution for the problem is formulated as a non linear mathematical programming exercise using household survey data from cote d ivoire the technique is applied to both urban and rural areas separately the paper concludes with a general discussion and suggestions for future research

market share market value and innovation in a panel of british manufacturing firms this paper examines the empirical relationship between technological innovations market share and stock market value new developments in the estimation of dynamic count data models are used to control for unobserved firm specific heterogeneity we find a robust and positive effect of market share on observable headcounts of innovations and patents although increased product market competition in the industry tends to stimulate innovative activity furthermore the impact of innovation on market value is larger for firms with higher market shares we argue that our results are consistent with models where high market share firms have incentives to pre emptively innovate

optimality of workfare with heterogeneous preferences with the standard non linear income taxation framework with heterogeneity of preferences in this paper the optimality of workfare as a screening tool is examined it is assumed that workfare does not serve as a human capital investment participation is mandatory and administrative costs are negligible imposing alternative cardinalizations on individuals utilities allows for the possibility that the government optimally redistributes income to or from high disutility of labour individuals under either case it is never optimal to impose workfare on these individuals it is also shown that non productive workfare can be an e cient policy tool in contrast to the results found in besley and coate 1995 brett 1998 and beaudry and blackorby 1997 jel classification h21 h23 optimalite du workfare en presence de preferences heterogenes l auteur examine l timalite du workfare en tant qu instrument de tamisage a l aide du cadre conceptuel traditionnel d imposition non lineaire des revenus en presence de preferences heterogenes on postule que le workfare n est pas un processus d investissement en capital humain que la participatioun est obligatoire et que les couts d administration sont negligeables quand on postule aussi des utilites cardinales differentes pour les individus il devient possible pour le gouvernement de redistribuer optimalement les revenus en faveur ou au detriment des individus pour qui le travail a une tres grande desutilite dans l un et l autre cas on montre que le workfare n est jamais une politique optimale on montre aussi que le workfare dans des activites non productives peut etre un instrument de politique publique e cient contrairement a ce qu a rment besley et coate 1995 brett 1998 et beaudry et blackorby 1997

internal r d effort external imported technoloogy and economic value added empirical study of taiwan s electronic industry technology innovation is a significant resource in the contemporary knowledge based economy the main sources of technology innovation are internal r d effort and external imported technology two primary traditional production factors are physical capital and labour the theoretical basis for this study is an evolutionary cobb douglas production function explaining the effects of four resources internal r d effort imported technology physical capital and labour on a firm s sales and economic value added eva time series cross section panel data from 219 taiwan electronic manufacturers between 1990 and 2003 were employed for fixed effect model major empirical findings were observed in this study first internal r d effort can positively affect a firm s sales and eva conversely imported technology is found to have had no significant effect on sales and eva second although both physical capital and labour affect a firm s sales more than the effects of internal r d and external imported technolog

the intertemporal behavior of economic profits abstract the intertemporal behavior of economic profits is examined tests show that profit rates are not independent of their initial level a set of tests for the nature of the profit adjustment mechanism is proposed and a stock market based profit measure is employed despite intertemporal dependence we find evidence of profit rate adjustment patterns roughly consistent with neoclassical theory for negative profits in some but not all cases the probability of maintaining positive profits appears less than the probability of moving toward zero profits

information technology effects on firm performance as measured by tobin s q despite increasing anecdotal evidence that information technology it assets contribute to firm performance and future growth potential of firms the empirical results relating it investments to firm performance measures have been equivocal however the bulk of the studies have relied exclusively on accounting based measures of firm performance which largely tend to ignore it s contribution to performance dimensions such as strategic flexibility and intangible value in this paper we use tobin s q a financial market based measure of firm performance and examine the association between it investments and firm q values after controlling for a variety of industry factors and firm specific variables the results based on data from 1988 1993 indicate that in all of the five years the inclusion of the it expenditure variable in the model increased the variance explained in q significantly the results also showed that for all five years it investments had a significantly positive association with tobin s q value our results are consistent with the notion that it contributes to a firm s future performance potential which a forward looking measure such as the q is better able to capture

why don t the poor save more evidence from health savings experiments using data from a field experiment in kenya we document that providing individuals with simple informal savings technologies can substantially increase investment in preventative health and reduce vulnerability to health shocks simply providing a safe place to keep money was sufficient to increase health savings by 66 percent adding an earmarking feature was only helpful when funds were put toward emergencies or for individuals that are frequently taxed by friends and relatives group based savings and credit schemes had very large effects

capacity investment and market power in the economic value of energy firms regulation of energy firms faces the complex problem of balancing private earning a fair rate of return on investment and public assure safe and reliable supply of energy at the lowest possible costs goals tobin s q is a forward looking indicator on investment opportunities and on market power of firms that energy regulators can use for more effective regulation this paper presents the empirical evidence on the determinants of differences in observed values of tobin s q for a sample of large listed energy firms from 10 different countries in the period 2000 2006 we find that adjustment costs represent around sixty percent of the difference between economic and book value of the assets for the representative firm while rents from market power represent the other forty percent therefore across countries there is room for regulatory actions aiming at reducing energy prices but less than what may be inferred from the observed average q values

modelling the take up of state support abstract we discuss the modelling of the take up of state support by going beyond the standard analysis and recognising that both the researcher and the welfare agency make errors is assessing entitlement we apply the discussion to an examination of the take up of supplementary benefits in britain by explicitly modelling the costs to taking up state support we can illustrate how these costs can dampen the welfare impact of state support and mitigate or aggravate welfare agency errors in assessing entitlement

profit rates and intangible capital a central question in industrial organization is why profit rates differ so dramatically across firms and industries one of the many explanations offered for this phenomenon is the failure of conventional accounting methods to adjust for intangible capital stocks i e it is argued that profit rates do not differ dramatically when capital stocks are correctly calculated to include intangible r d and advertising capital to test this hypothesis individual advertising capital stocks are calculated for firms in the toys distilled beverages cosmetics and pharmaceuticals industries and r d stocks are calculated for the pharmaceuticals firms the adjustments do not eliminate the wide dispersion in profit rates copyright 1991 by mit press

income distribution and price controls targeting a social safety net during economic transition abstract during the ongoing post communist economic transitions the relative well being of many people is changing rapidly and governments are not well positioned to accurately measure individual living standards under such circumstances continued price controls over basic consumer goods within the state sector and the associated queuing can form a serviceable device for targeting poor people for subsidies with a fixed price state sector and free price parallel markets rich people might choose to avoid queues and shop in the free markets while poor people would prefer to pay low nominal prices and queue in the state sector the targeting of subsidies through queues therefore can be accomplished even if the government has no information concerning individual income or living standards when the alternative to price controls is a poorly targeted explicit social safety net the resource cost of queues might be more than offset by an improvement in the targeting of subsidies

public investment and industry incentives in life science research life science research has shifted rapidly from the public to the private sector raising questions about government s remaining role we shed light on the issue by employing a dynamic investment response model to examine the public s impact on industry life science research effort and success we find that government expenditures in both basic biological research and agricultural and medical science create substantial spillovers for private firms the spillovers are unfortunately partly nullified by government competition for scarce research inputs yet even after accounting for such competition public investment has been strongly complementary to private investment indeed opportunities created through public research are the principal source of growth in industry life sciences copyright 2007 oxford university press

rational inattention optimal consideration sets and stochastic choice we unite two basic approaches to modelling limited attention in choice by showing that the rational inattention model implies the formation of consideration sets only a subset of the available alternatives will be considered for choice we provide necessary and sufficient conditions for rationally inattentive behaviour which allow the identification of consideration sets in simple settings chosen options are those that are best on a stand alone basis in richer settings the consideration set can only be identified holistically in addition to payoffs prior beliefs impact consideration sets linear inequalities identify all priors consistent with each possible consideration set

public goods self selection and optimal income taxation using the self selection approach to tax analysis this paper derives a modified samuelson rule for the provision of public goods when the government deploys an optimal nonlinear income tax this approach gives a straightforward interpretation of the central result in this area generalises it and provides a simple characterisation of optimal policy in a wide range of circumstances the analysis also emphasises and clarifies the significance of the choice of numeraire for the optimality of decentralising public spending decisions it is well known that the famous samuelson rule for the provision of public goods may not be applicable when the tax revenues used to finance the public goods come from distorting taxes the principle was recognized as long ago as pigou 1947 long before the samuelson rule was devised pigou saw that in addition to the resource cost involved in transferring funds from the private to the public sector there was a deadweight loss involved from this insight he suggested that the criterion for providing public goods should be more stringent than the samuelson rule would later suggest in particular one might expect that the inclusion of the deadweight loss of taxes as part of the cost of providing a public good would lead to a reduction in its optimal provision relative to a situation in which lump sum taxes were available the problem was investigated more systematically by atkinson and stern 1974 who considered the case in which a public good is financed by a set of optimal commodity taxes all individuals were assumed to be identical so efficiency alone dictated the objective they found that no prima facie case could be made for the pigou position that the use of distortionary taxes called for a reduction in the supply of the public good their analysis clearly showed that there were two influences at work when the financing of a public good was by distorting taxes on the one hand

topping up or opting out the optimal design of public provision schemes there is extensive public provision of private goods in all developed countries the public provision scheme is often designed so that individuals can opt out but not top up supplement the publicly provided quantity quality using an optimal income ta

how should consumers willingness to pay be measured an empirical comparison of state of the art approaches abstract this study compares the performance of four commonly used approaches to measure consumers willingness to pay with real purchase data real the open ended oe question format choice based conjoint cbc analysis becker degroot and marschak s bdm incentive compatible mechanism and incentive aligned choice based conjoint icbc analysis with this five in one approach the authors test the relative strengths of the four measurement methods using real as the benchmark on the basis of statistical criteria and decision relevant metrics the results indicate that the bdm and icbc approaches can pass statistical and decision oriented tests the authors find that respondents are more price sensitive in incentive aligned settings than in non incentive aligned settings and the real setting furthermore they find a large number of none choices under icbc than under hypothetical conjoint analysis this study uncovers an intriguing possibility even when the oe format and cbc analysis generate

what matters and what does not in households decision to invest in malaria prevention this paper examines the take up of a new malaria control device by rural households in kenya and tests whether the demand curve for the device varies with the framing of marketing messages and with the gender of the person targeted by the marketing previous research suggests that the demand for malaria prevention is highly price sensitive jessica cohen and dupas 2008 even though the private returns to preventing malaria are very large christian lengeler 2004 in the standard model of investment in human capital individuals invest in a health product if the expected benefits from the product outweigh its costs michael grossman 1972 in this framework the low take up observed at relatively moderate prices by cohen and dupas 2008 could be due to people underestimating the expected benefits of investing in prevention or due to people being credit constrained and unable to pay the cost up front it is also possible that the standard model does not apply because people have time inconsistent preferences or because they are uncertain about their own preferences and rely on external cues to resolve their own uncertainty when they need to make a decision an extensive literature in psychology and marketing suggests that decision making can be affected by frames or cues that do not add information about a product but can be effective at persuading individuals to invest in it for example in a recent field experiment in south africa marianne bertrand et al 2008 found what matters and what does not in households decision to invest in malaria prevention

majority voting with single crossing preferences we clarify and extend a number of sufficient conditions for the existence of a majority voting equilibrium on one dimensional choice domains these conditions variously stated in the previous literature all impose order restrictions on voter preferences for instance monotone marginal rates of substitution which we show to imply or be equivalent to a general ordinal version of the single crossing condition this simple property is economically intuitive and easily checked in applications this ease of application is demonstrated through an examination of voting models of redistributive income taxation and trade union bargaining behaviour

optimal redistribution with productive social services publicly provided private goods are conventionally considered consumer goods departing from this perspective we analyze the public provision of inputs that improve household productivity e g education and childcare in a two class economy with distorting taxation public provision is always welfare improving with respect to pure taxation given that the public input directly affects household productivity moreover the case for public provision strengthens as households heterogeneity in input demand fades out contrary to consolidated results in the literature the features of optimal provision schemes depend on the nature of publicly provided input namely if it substitutes household productive capacity or just helps households to exploit it

keeping the doctor away experimental evidence on investment in preventative health products household investment in preventative health products in developing countries is typically low even though the returns to such products are high in this paper we experimentally estimate demand curves for health products and test whether 1 information about health risk 2 cash liquidity 3 peer effects and 4 intra household differences in preferences affect demand in our main experiment in kenya involving children s shoes critical for preventing hookworm infection price is by far the most important predictor of purchase providing liquidity and targeting women also increased demand information had no effect even though we find that genuine learning occurred we find no peer effects even though people discussed the product purchase decision extensively we find similar results for price and information in three smaller studies in guatemala india and uganda in experiments involving soap and multivitamins

innovation appropriability and the underpricing of initial public offerings using the information asymmetries theory of underpricing we investigate the role of innovation in the underpricing of initial public offerings ipos we develop and test a model in which patents reduce information asymmetries in industries where the link between patents and inventive returns is transparent thereby reducing underpricing conversely patents reflect increased information asymmetries and underpricing in industries where the link is not transparent we examine these relationships in a sample of 1 413 ipos and find strong support for our hypotheses in so doing we make an important theoretical contribution by showing that the ipo market contextualizes firm information abstract from author copyright of academy of management journal is the property of academy of management and its content may not be copied or emailed to multiple sites or posted to a listserv without the copyright holder s express written permission however users may print download or email articles for individual use this abstract may be abridged no warranty is given about the accuracy of the copy users should refer to the original published version of the material for the full abstract copyright applies to all abstracts

do low income housing subsidies increase the occupied housing stock abstract a necessary condition for justifying a policy such as subsidized low income housing either via tenant based rental assistance or construction of public or private projects is that it has a real effect on market outcomes in this paper we examine one aspect of the real effect of subsidized housing does it increase the housing stock if subsidized housing raises the quantity of occupied housing per capita either more people are finding housing or they are being housed less densely on the other hand if subsidized housing merely crowds out equivalent quality low income housing that otherwise would have been provided by the private sector the housing policy may have little real effect on housing consumption using both census place and msa level data from the decennial census and from the department of housing and urban development we ask whether housing markets with more subsidized housing also have more total housing after accounting for housing demand we find that government financed units raise the total number of units in a market although on average one government subsidized unit adds only one third to one half of a unit to the total housing stock there is less crowd out in more populous markets and more crowd out in places where there is less excess demand for subsidized housing as measured by the number of government financed units per eligible person tenant based housing programs such as section 8 certificates and vouchers seem to be more effective than project based programs at targeting subsidized housing units to people who otherwise would not have their own

can higher prices stimulate product use evidence from a field experiment in zambia the controversy over how much to charge for health products in the developing world rests in part on whether higher prices can increase use either by targeting distribution to high use households a screening effect or by stimulating use psychologically through a sunk cost effect we develop a methodology for separating these two effects we implement the methodology in a field experiment in zambia using door to door marketing of a home water purification solution we find evidence of economically important screening effects by contrast we find no consistent evidence of sunk cost effects jel c93 d12 i11 m31 o12

large cash transfers to the elderly in south africa we examine the social pension in south africa where large cash sums about twice the median per capita income of african households are paid to people qualified by age but irrespective of previous contributions we present the history of the scheme and use a 1993 nationally representative survey to investigate the redistributive consequences of the transfers documenting who receive the pensions their levels of living and those of their families we also look at behavioural effects particularly the effects of the cash receipts on the allocation of income to food schooling transfers and savings in south africa a large social pension about twice the median per capita income of african households is paid in cash to people qualified by age irrespective of previous contributions we present the history of the scheme and explain how such large transfers could come about in an economy in which the recipients were not only politically weak but without any political representation whatsoever we then use a 1993 nationally representative survey to investigate the redistributive consequences of the transfers documenting who receive the pensions their levels of living and those of their families we also look at behavioural effects particularly the effects of the cash receipts on the allocation of income to food schooling transfers and savings the pressing policy issue for south africans is whether it makes sense to target seven billion rand nearly 2 billion of social expenditure through the current pension schemes our analysis contributes to the discussion by documenting the redistributive and behavioural effects of the transfers we find that at least as far as immediate incidence is concerned and without allowance for behavioural effects the social pension is an effective tool of redistribution and that the households it reaches are predominantly poor because so many of the elderly among south africa s african population live with children the social pension is also effective in putting money into house

the returns to r d in tobin q models and the option value of future r d abstract this paper argues that the tobin q literature under estimates the r d stock used by investors in calculating market values and significantly over estimates the returns to r d thereby questioning the conclusion that there is private under investment in r d

on the form of transfers to special interests an important question in political economy concerns the form of transfers to special interests the chicago view is that political competition leads politicians to make such transfers efficiently the virginia position is that lack of information on the part of voters leads politicians to favor inefficient sneaky methods of redistribution this paper analyzes the form of transfers in a model of political competition in which politicians have incentives to make transfers to special interests it shows that when voters have imperfect information about both the effects of policy and the predispositions of politicians inefficient methods of redistribution may be employed

do non monetary prices target the poor evidence from a field experiment in india monetary price subsidies are often used to increase take up of health products but monetary prices may screen out those with the highest returns the poor using willingness to pay wtp data from a field experiment in india this paper determines whether nonmonetary prices better target health products to the poor than monetary prices it is found that monetary wtp is increasing in income and nonmonetary wtp is weakly decreasing in income comparing across price types nonmonetary wtp falls relative to monetary wtp as income rises nonmonetary prices better target the poor than monetary prices a larger fraction of total demand is poor

patents as indicators of corporate technological strength abstract quantitative indicators of the technological strengths of individual companies would be an important addition to the financial and economic data used in competitor assessments merger acquisition analyses investment decisions and corporate planning and management this paper examines the links between corporate patent and patent citation data and several other indicators of corporate performance changes in sales and profits research and development budgets scientific productivity and expert opinions of company technological strength the study covers 17 us pharmaceutical companies for which financial r d and expert opinion data were readily available for these pharmaceutical companies it was found that the patent data are an excellent indicator of overall corporate technological strength with 1 an overall correlation of 0 82 between expert opinion of pharmaceutical company technical strength and the number of us patents granted to the companies and 2 correlations in the general range of 0 6 to 0 9 between increases in company profits and sales and both patent citation frequency and concentration of company patents within a few patent classes

determinants of cross national knowledge transfer and its effect on firm innovation this study examines the determinants of international knowledge flow from a resource based perspective it evaluates the impact of cross national knowledge transfer on firm innovative performance based on 56 027 us patents owned by 53 selected firms in the us based pharmaceutical industry the results suggest that innovative performance is a curvilinear function of the international knowledge content used by a firm to innovate as hypothesized it was found that at 1 low and moderate levels of international knowledge content a firm s strategy to transfer international knowledge improves its innovative performance and at 2 higher levels of international knowledge content there are diminishing marginal returns to transferring knowledge from overseas

targeting in medicaid the costs and enrollment effects of medicaid s citizenship documentation requirement abstract the deficit reduction act of 2005 imposed a federal requirement that all individuals provide citizenship documentation when applying for or renewing medicaid coverage this represented a change in policy for 46 states using differences in differences to analyze data from the current population survey 2004 2008 this paper shows that the policy reduced medicaid enrollment among non citizens as intended and did not significantly affect citizens one in four adult non citizens in medicaid 390 000 total and one in eight child non citizens 81 000 were screened out by the policy annually child non citizens were more likely to become uninsured afterwards while adult non citizens appeared to shift from medicaid to other coverage overall the citizenship documentation requirement reduced medicaid participation among non citizens in an appropriately targeted way nonetheless a cost benefit analysis indicates that the policy was a net loss to society of 600 million through increased state administrative spending and compliance costs imposed on u s citizens applying for medicaid

measuring design investment in firms conceptual foundations and exploratory uk survey abstract the importance of design to company and national performance has been widely discussed with a number of studies investigating the value or impact of design on performance however none of these studies has measured design investment as an input against which performance can be compared as yet there is no established way in which design investment might be measured without such a method we cannot develop a reliable picture akin to that for r d spending on the impact of design spending on company performance this paper presents a conceptual framework for the measurement of design investment and applies this framework in a survey of uk firms the framework describes design as being part of the creation and commercialization of new products and services the survey highlights some surprising patterns of design spend in the reported sample and demonstrates the viability of the underpinning framework a revised framework is proposed that situates design investment in the context of r d the model has implications for policy makers trying to understand the role and scale of design in the private sector for managers wishing to optimize their design investments and for academics seeking to measure the value of design

take up and targeting experimental evidence from snap this paper develops a framework for evaluating the welfare impact of various interventions designed to increase take up of social safety net programs in the presence of potential behavioral biases we calibrate the key parameters using a randomized field experiment in which 30 000 elderly individuals not enrolled in but likely eligible for the supplemental nutrition assistance program snap are either provided with information that they are likely eligible provided with this information and also offered assistance in applying or are in a status quo control group only 6 percent of the control group enrolls in snap over the next 9 months compared to 11 percent of the information only group and 18 percent of the information plus assistance group the individuals who apply or enroll in response to either intervention receive lower benefits and are less sick than the average enrollee in the control group the results are consistent with the existence of optimization frictions that are greater for needier individuals suggesting that the poor targeting properties of the interventions reduce their welfare gains

the illusion of sustainability this brief summarizes the results of a gender impact evaluation study entitled the illusion of sustainability conducted during the time period 1998 to 2001 in kenya the study observed that deworming is a public good since much of its social benefit comes through reduced disease transmission people were less likely to take deworming if their direct first order or indirect second order social contacts were exposed to deworming the introduction of a small fee for deworming drugs led to an 80 percent reduction in treatment rates take up was not sensitive to the exact price level suggesting that it is particularly counter productive to charge small positive prices for the treatment of infectious diseases an intensive school health education had no impact on worm prevention funding for the study derived from world bank nih fogarty international center berkeley center for health research

improving patent valuations for management purposes validating new indicators by analyzing application rationales abstract this paper analyzes the validity of so far untested indicators of patent value to enhance the quality of patent assessments using indicators at the corporate level the article expands the theory by eliciting patent attorneys filing rationales to maximize profits from protecting intellectual property to inspire the computation of new value indicators including patent full texts then based on a newly compiled data set consisting of 813 ep patents the probability of an opposition against a patent is modeled by established and new value indicators the results show that accelerated examination requests and qualified word counts enhance the quality of existing valuation methods

value implications of investments in information technology the year 2000 y2k countdown provided a uniquely visible instance of spending on information technology it by u s companies with public attention riveted on potential y2k malfunctions managers were forced to evaluate their it and make decisions about whether to modify or replace existing systems in the aftermath of y2k critics charged that the problem was overblown and that companies overspent on it in contrast we posit in this paper that efforts companies made to renew and upgrade their it may have positioned them to take advantage of new e business applications as y2k approached managers could invest opportunistically in it which would enable them to connect with customers and suppliers in new ways contrary to the alleged overspending we find that firm value increased on average with y2k spending by fortune 1000 companies in particular higher firm value and subsequent earnings were associated with y2k spending for firms in industries where it was considered to have a transforming influence altering traditional ways of doing business by redefining business processes and relationships we also test whether the positive association between firm value and y2k spending diminished with y2k spending by industry peer firms but we do not find support for this relative investment hypothesis

an analysis of the efficiency of the oil refining industry in the oecd countries abstract this study investigated the efficiency of the oil refining industry using the two stage method of markowitz portfolio optimization theory and panel data analysis of about 30 oecd countries from 2005 to 2016 which is a new methodology for measuring the efficiency of the oil industry the oil refining industry s efficiency is derived from the prices of petroleum products naphtha gasoline kerosene diesel and fuel oil using the portfolio theory the panel data was constructed using the following dependent variables the crude oil production efficiency energy consumption renewable energy consumption and r d investment using the panel data analysis empirical analyzes are conducted on how the efficiency of the oil refining industry is affected by explanatory variables the results show that crude oil production and energy use in oecd countries have a negative effect on the efficiency of the oil refining industry and consumption of renewable energy and r d investment have a positive effect contrary to conventional perception the petroleum industry can coexist with the renewable energy industry for sustainable development

intangible capital aspects of advertising and r d expenditures twenty years have passed since economists first emphasized the intangible capital aspects of advertising according to this view consumers tend to forget brands and continuous advertising is needed to maintain a given rate of sales thus advertising expenditures can be viewed as a capital good that depreciates over time and needs maintenance and repair 22 p 197 more recently weiss 25 among others has suggested that research and development r d costs might also be capitalized as such expenditures yield benefits mainly in the future 25 p 421 unfortunately most analyses of the intangible capital issue have been limited to advertising largely because no comprehensive data on r d were available until quite recently however important recent theoretical contributions on the topic and improvements in data availability now make it possible more completely to consider the intangible capital aspects of both advertising and r d expenditures here the intangible capital issue is investigated through use of a market valuation model in this approach significant future intangible capital effects of advertising and r d are suggested to the extent that current expenditures have significant effects on the market value of the firm given positive market value influences individual coefficient estimates can be used to estimate both the total stock of intangible capital as well as average annual depreciation rates for advertising and r d while these depreciation rate estimates are interfirm averages and undoubtedly err in individual instances they can be quite useful in indicating the general magnitude of corporate profit and tax misstatement due to current reporting and tax policies in section i below various articles closely related to this study are reviewed section ii develops a valuation model embodying intangible capital considerations the data are discussed in section iii and estimation results are presented in section iv and finally conclusions and implications for public policy are discussed in section v

targeting transfers through restrictions on recipients our objective is to design transfer programs that maximize some social welfare function following the optimal income tax formulation we assume that a random process endows individuals with characteristics that influence welfare such as ability to earn income medical condition or unmonitorable income the goal is to maximize the utility of a randomly chosen individual other individualistic social welfare functions would lead to equivalent results if the random characteristics were observable a first best outcome could be achieved by making them the basis for lump sum transfers in practice however we can observe only indicators of these characteristics such as earnings medical expenditures or consumption patterns the challenge for policy is to design an efficient second best transfer program based on indicators in this paper we argue that 1 an optimal transfer program in general must sacrifice productive efficiency to target efficiency this is done by imposing restrictions on the choices made by intended beneficiaries 2 a program that incorporates restrictions such as means tested in kind transfers commodity specific taxes and subsidies and even ordeals i e the imposition of deadweight costs to qualify for a transfer will perform better than programs that rely solely on income taxes and cash transfers

co ownership of intellectual property exploring the value appropriation and value creation implications of co patenting with different partners combining both interview data and empirical analyses at the patent and firm levels we explore the value appropriation and value creation implications of r d collaboration resulting in the co ownership of intellectual property i e co patents we make an explicit distinction between three different types of co patenting partners intra industry partners inter industry partners and universities our findings indicate that the value appropriation challenges of ip sharing are clearly evident with intra industry co patenting where partners are more likely to encounter overlapping exploitation domains co patenting with universities is associated with higher market value since appropriation challenges are unlikely to play a role and collaboration may signal novel technological opportunities although we find some evidence that co patenting corresponds to higher patent value patents co owned with firms are significantly less likely to receive self citations indicating constraints on the future exploitation and development of co owned technologies

union rent seeking intangible capital and market value of the firm abstract this study considers the effect of unions on intangi ble capital investment and profitability within the context of a market value rather than a more traditional accounting based approach theory is provided suggesting unions are able to affect profitability by sharing in the economic returns to firm specific intangible capital in support of this hypothesis we find unionization reduces the returns to r d and produces a corresponding limiting influence on r d investment at the firm level i introduction a n extensive literature in economics has ex amined the determinants of profitability with much of the focus centering on the role of market structure only recently however have the effects of labor unions on profitability been analyzed ths is surprising since labor economists long have emphasized union influences on wages and productivity that in turn may affect profitabil ity in recent studies freeman 1983 and karier 1985 report a significant limiting influence of unions on price cost margins in high concentra tion manufacturing industries using firm level data and the market based tobin s

testable competing hypotheses from structure performance theory efficient structure versus market power this paper provides a structure performance theory that can accommodate leading firm efficiency as well as several competing market power hypotheses the author derive s testable implications distinguishing the simple collusion product differentiation and scale economy hypotheses from the innovative lea ding firm alternative it is shown that recent evidence of a positive market share price cost margin pcm relationship and a nonpositive concentration pcm relationship can reject the scale economy and simpl e collusion hypotheses in homogeneous product markets unfortunately this same evidence cannot reject the product differentiation hypothe sis in favor of leading firm efficiency copyright 1988 by blackwell publishing ltd

distinguishing income from substitution effects in disability insurance a set of studies conducted over the last 15 years has produced a near consensus that the social security disability insurance system ssdi has substantial disincentive effects on the labor supply of near elderly males diminishing labor force participation increasing the sensitivity of labor force exit decisions to adverse economic shocks and encouraging those nearing retirement to claim disability benefits and subsequently transfer into the social security retirement program yet efforts by the social security administration ssa to encourage labor supply among the disabled by removing the work disincentives built into ssdi have been almost entirely unsuccessful most notably in 1999 congress authorized the ticket to work program which provides an array of inducements for current ssdi beneficiaries to take up employment including permitting a trial work period of up to nine months providing 7 75 years of ongoing medicare eligibility following return to work and providing three years of automatic benefit reinstatement when claimants workplace earnings fall below a threshold level each of these steps reduces the implicit tax placed on labor supply by the ssdi program despite these lures fewer than 1 400 0 01 percent of the 12 2 million tickets issued to date have led to successful workforce integration autor and duggan 2006

inter industry differences in profitability the legacy of the structure efficiency debate revisited this study presents a simple model on the sources of inter industry variation in profitability and tests its empirical implications in order to shed new light on the long lasting debate over industry profitability the model identifies four key factors that jointly influence an industry s price cost margin i the intensity of strategic investment e g r d and advertising ii the skewness of the distribution of market share or market concentration iii the appropriability of strategic investment and iv the extent to which firms market shares are determined by the intensity of their strategic investment these factors are expected to be positively related to industry profitability and our empirical analysis provides supportive evidence the model also suggests that the conventional single dimensional hypotheses on profitability the market power or market structure hypothesis and the efficiency hypothesis are overly simplified more importantly existing empirical results allegedly supporting each of these hypotheses are spurious to the extent that the distribution of firm specific strategic competence reflects firm heterogeneity in efficiency and at the same time underlies the distribution of market share or market concentration copyright 2009 oxford university press

the dynamics of innovative activity and competitive advantage the case of australian retail banking 1981 to 1995 this study examines the adoption of new products and processes in the australian retail banking industry over the 1981 to 1995 period our analysis demonstrates that the vast majority of observed innovative activity was based on ideas sourced from outside the focal firm and that innovations diffused very quickly across competing banks as such there were no periods during which any bank had proprietary possession of a major product or process innovation we therefore ask how the banks innovative activity could affect their relative financial performance positions we answer this question by developing a set of hypotheses that relate specific features of their histories of innovative activity to their current financial performance these hypotheses are tested using a detailed data set describing 1 297 modifications made to products and services distribution technologies and back office processes within a sample of australian retail banks over the sample period our results provide support for the general position that establishing an attractive competitive position depends on the specific history of a firm s innovative activity banks that undertook more innovative activity that were more consistent in that activity and whose composition of activity was somewhat differentiated from the industry norm tended to display superior financial performance rather than looking solely for internally generated inimitable innovations to deliver competitive advantage these results suggest that active and consistent innovative activity that is somewhat differentiated from competitors can also deliver superior financial performance

micro loans insecticide treated bednets and malaria evidence from a randomized controlled trial in orissa india we describe findings from the first large scale cluster randomized controlled trial in a developing country that evaluates the uptake of a health protecting technology insecticide treated bednets itns through micro consumer loans as compared to free distribution and control conditions despite a relatively high price 52 percent of sample households purchased itns highlighting the role of liquidity constraints in explaining earlier low adoption rates we find mixed evidence of improvements in malaria indices we interpret the results and their implications within the debate about cost sharing sustainability and liquidity constraints in public health initiatives in developing countries

the becker degroot marschak mechanism is not necessarily incentive compatible even for non random goods abstract this paper uses results from karni e safra z 1987 preference reversals and the observability of preferences by experimental methods econometrica 55 675 685 and karni e 1989 generalized expected utility analysis of multivariate risk aversion international economic review 30 297 305 to show that the becker degroot marschak mechanism is not always incentive compatible even when the item to be valued involves no uncertainty contrary to several recent assertions

worms at work long run impacts of a child health investment this study estimates long run impacts of a child health investment exploiting community wide experimental variation in school based deworming the program increased labor supply among men and education among women with accompanying shifts in labor market specialization ten years after deworming treatment men who were eligible as boys stay enrolled for more years of primary school work 17 more hours each week spend more time in nonagricultural self employment are more likely to hold manufacturing jobs and miss one fewer meal per week women who were in treatment schools as girls are approximately one quarter more likely to have attended secondary school halving the gender gap they reallocate time from traditional agriculture into cash crops and nonagricultural self employment we estimate a conservative annualized financial internal rate of return to deworming of 32 and show that mass deworming may generate more in future government revenue than it costs in subsidies

revealed preference rational inattention and costly information acquisition we develop a revealed preference test for optimal acquisition of costly information the test encompasses models of rational inattention sequential signal processing and search we provide limits on the extent to which attention costs can be recovered from choice data we experimentally elicit state dependent stochastic choice data of the form the tests require in simple cases tests con rm that subjects adjust their attention in response to incentives as the theory dictates

price subsidies diagnostic tests and targeting of malaria treatment evidence from a randomized controlled trial author s dupas pascaline cohen jessica schaner simone abstract both under and over treatment of communicable diseases are public bads but efforts to decrease one run the risk of increasing the other using rich experimental data on household treatment seeking behavior in kenya we study the implications of this tradeoff for subsidizing life saving antimalarials sold over the counter at retail drug outlets we show that a very high subsidy such as the one under consideration by the international community dramatically increases access but nearly half of subsidized pills go to patients without malaria we study two ways to better target subsidized drugs reducing the subsidy level and introducing rapid malaria tests over the counter

dynamic logit with choice aversion we characterize a generalization of discounted logistic choice that incorporates a parameter to capture different views the agent might have about the costs and benefits of larger choice sets the discounted logit model used in the empirical literature is the special case that displays a preference for flexibility in the sense that the agent always prefers to add additional items to a menu other cases display varying levels of choice aversion where the agent prefers to remove items from a menu if their ex ante value is below a threshold we show that higher choice aversion as measured by dislike of bigger menus also corresponds to an increased preference for putting off decisions as late as possible

the value of intellectual property rights to firms and society economists view intellectual property rights iprs as policy tools for encouraging innovation but they recognize that they can also inhibit competition there are many types of iprs and institutions concerned with their administration we begin by outlining how these complex and varied rights are supposed to work and how they interact with other characteristics of firms and markets we then survey the available literature on patents trade marks and copyright to assess the value of these iprs to firms and the costs to firms of acquiring and defending their rights the paper concludes with suggestions for topics requiring further research to inform public policy better

market value r d and patents abstract a significant relationship is found between the market value of the firm and its intangible capital proxied by past r d expenditures and the number of patents based on a time series cross section analysis of data for large u s firms

free distribution or cost sharing evidence from a randomized malaria prevention experiment author s cohen jessica dupas pascaline abstract it is often argued that cost sharing charging a subsidized positive price for a health product is necessary to avoid wasting resources on those who will not use or do not need the product we explore this argument through a field experiment in kenya in which we randomized the price at which prenatal clinics could sell long lasting anti malarial insecticide treated nets itns to pregnant women we find no evidence that costsharing reduces wastage on those that will not use the product women who received free itns are not less likely to use them than those who paid subsidized positive prices we also find no evidence that costsharing induces selection of women who need the net more those who pay higher prices appear no sicker than the average prenatal client in the area in terms of measured anemia an important indicator of malaria cost sharing does however considerably dampen demand we find that uptake drops by 75 percent when the price of itns increases from zero to 0 75 i e from 100 to 87 5 percent subsidy the price at which itns are currently sold to pregnant women in kenya we combine our estimates in a cost effectiveness analysis of itn prices on child mortality that incorporates both private and social returns to itn usage overall our results suggest that free distribution of itns could save many more lives than cost sharing programs have achieved so far and given the large positive externality associated with widespread usage of itns it would likely do so at a lesser cost per life saved

intangible resources tobin s q and sustainability of performance differences this paper tests empirically the hypothesis that the greater the intangibility of a firm s resources the greater the sustainability of its competitive advantage resource intangibility is measured by 1 tobin s q and 2 the predicted value from a hedonic regression of q on several accounting measures of intangibles sustainability is measured by the persistence of firm specific profits using a dynamic panel data regression model i find that intangibles play an effective role in sustaining a firm s competitive advantage as predicted by the resource based view of the firm however the results suggest that intangibles can also lock firms into persistent disadvantages

subsidies as sorting devices abstract the divergence between tax payments and the cost of providing public services that arise from financing local public services provides an incentive for higher income communities to deter the entry of lower income households into their community here we demonstrate that higher income households to insure that low income households do not enter their community or reduce the number that do enter subsidize goods consumed by higher income households more than by lower income households this strategy will make the rich community less attractive to the poor deterring their entry to the community

short run subsidies and long run adoption of new health products evidence from a field experiment short run subsidies for health products are common in poor countries how do they affect long run adoption a common fear among development practitioners is that one off subsidies may negatively affect long run adoption through reference dependence people might anchor around the subsidized price and be unwilling to pay more for the product later but for experience goods one off subsidies could also boost long run adoption through learning this paper uses data from a two stage randomized pricing experiment in kenya to estimate the relative importance of these effects for a new improved antimalarial bed net reduced form estimates show that a one time subsidy has a positive impact on willingness to pay a year later inherit to separately identify the learning and anchoring effects we estimate a parsimonious experience good model estimation results show a large positive learning effect but no anchoring we black then discuss the types of products and the contexts inherit for which these results may apply

market structure and market value while the use of market models to determine the sources of economic profits is quite new at least two empirical studies considering the market structure and market value relation have appeared to date interestingly they conflict thomadakis 1977 found a close positive relation between the four firm concentration ratio and relative excess valuation measured as the difference between the market value of the firm and the book value of tangible assets all normalized by sales as a result thomadakis argued that industry concentration plays a role in the determination of excess profits from currently held assets and those expected from the firm s investment options p 185 in contrast lindenberg and ross 1981 reported no significant relation between concentration and tobin s q ratio measured as the ratio of the market value of the firm to the replacement cost of tangible assets this result disputes thomadakis s findings and a purely structuralist interpretation of economic profits according to lindenberg and ross market power may or may not be evident in highly concentrated markets since high q s can occur in concentrated or unconcentrated markets and conversely low q s indicating no significant market power can occur in markets that have high degrees of concentration p 28

risk aversion and the choice between risky prospects the preservation of comparative statics results most results in what can be termed the comparative statics of risk aversion are obtained when there is only one source of uncertainty the primary example which originally motivated the definition of risk aversion is that more risk averse people are willing to pay a higher premium for insuring against risk it is known that the results do not generally carry over when there is another source of uncertainty the paper develops conditions under which comparative statics results are robust against the introduction of additional sources of uncertainty

the durability of advertising revisited recent cross section studies find that advertising is relatively long lived providing support for treating advertising as capital this paper models the firm s advertising decision treating advertising and product quality as complements the model predicts that failing to control for differences in firm specific factors positively correlated with the return to advertising will understate advertising s direct effect on sales and overstate its durability the authors empirical study using several years of data for over four hundred firms confirms these predictions advertising s apparent life shrinks dramatically when firm specific factors are held constant they also find no support for the steady state assumptions critical to intangible assets models copyright 1994 by blackwell publishing ltd

the effect of recipient contribution requirements on support for social programs abstract a large literature examines the use of recipient contribution requirements in social programs to target people who most need and value aid yet little is known about public support for such requirements in a field experiment with a nationally representative sample we examine the effect of recipient contributions on charitable donations to a food aid program the response to recipient monetary contributions is non monotonic donations increase when recipients make small monetary contributions and return to baseline under large recipient contributions recipient time contribution requirements also increase program support results from additional treatments suggest that individuals use contribution requirements to increase both allocative efficiency screening recipients who most value the good and targeting efficiency screening recipients most in need our work informs the design of social programs which must respond to the preferences of voters and donors who provide political and financial support

can public works increase equilibrium wages evidence from india s national rural employment guarantee abstract we estimate the impact of the world s largest public works program india s national rural employment guarantee scheme nregs on agricultural wages nregs was rolled out across india in three distinct phases and this phased introduction is used to identify difference in difference estimates of the program effect using monthly data on wage rates from the period 2000 2011 in 209 districts across 18 indian states we include district specific fixed effects and trends to control for differences in wage rates in the absence of the program we find that on average the program boosted the growth rate of real daily agricultural wages by 4 3 per year the effect of the scheme is more consistent with an increase in the growth rate of wages than with a discontinuous jump in wages the effect was concentrated in some states and in the agricultural peak season appears to have been gender neutral and was biased towards unskilled labor since many of the world s poorest depend on casual agricultural labor for their livelihood while at the same time minimum wage legislation is unlikely to be effective in many developing countries we argue that rural public employment programs constitute a potentially important anti poverty policy tool

the value of u s patents by owner and patent characteristics abstract this paper uses renewal data to estimate the value of u s patents controlling for patent and owner characteristics estimates of u s patent value are substantially larger than estimates for european patents however the ratio of u s patent value to r d for firms is only about 3 contrary to a common assertion patents issued to small patentees are much less valuable than those issued to large corporations litigated patents are more valuable as are highly cited patents however patent citations explain little variance in value suggesting limits to their use as a measure of patent quality

the impact of corporate governance practices on r d efforts a look at shareholders rights cross listing and control pyramid the paper considers the impact of multiple shareholder oriented governance practices on rd decisions based on a sample of 5 528 firms belonging to 110 large french listed business groups our results substantiate the idea that shareholder oriented governance practices and a lower position in a control pyramid are better for rd investment the introduction of any additional shareholder oriented practice is found to result in more rd we show however that this anglo americanization of the french corporate governance system is only partial we provide evidence of the co existence of an old french system of corporate governance with a hybrid model of corporate governance the lack of concrete results on complementarity among shareholder oriented governance practices casts doubt on the stability of this hybrid model in the french context

rates of return on corporate investment in the last two decades productivity has lagged in the united states markets have been lost to foreign competition real income per capita has grown slowly this experience has led to considerable discussion of possible causes 7 one possible cause often mentioned is the quality of managerial investment decisions managers have been accused of overinvesting in obsolete technologies of underinvesting in risky projects with long run payoffs of undertaking unprofitable mergers and of overall poor judgment in their investment policies 39 this paper presents evidence on the returns on investment over the 1970 88 period for a sample of 699 large corporations that is consistent with this view

the regional distribution of public employment theory and evidence abstractthe regional distribution of public employment theory and evidence regional studies this article analyzes the optimal regional pattern of public employment in an information constrained second best redistribution policy it shows that regionally differentiated public employment can serve as an expenditure side tagging device bypassing or relaxing the equity efficiency trade off the optimal pattern exhibits higher levels of public employment in low productivity regions and is more pronounced the higher is the degree of regional inequality empirically using a panel of european regions from 1995 to 2007 the analysis finds evidence that public employment is systematically higher in low productivity regions the latter effect is stronger in countries with higher levels of regional inequality

consumption and poverty how effective are in kind transfers the ability of in kind transfers to alleviate poverty depends on accurate targeting as well as recipients valuations of the benefits using data from the consumer expenditure surveys the efficiency of in kind transfers is examined in a microsimulation framework in which recipients are identified as those who have the lowest consumption in this framework in kind transfers of food capital services which includes housing and consumer services are an effective means of providing support to the poor even at high levels of subsidization the multiple good transfers that are considered are essentially equivalent to cash grants copyright 1996 by royal economic society

patent quality and research productivity measuring innovation with multiple indicators we analyse the determinants of the decline in research productivity using panel data on manufacturing firms in the us for the period 1980 93 we focus on three factors the level of demand the quality of patents and technological exhaustion we develop an index of patent quality using detailed patent information and show that using multiple indicators substantially reduces the measured variance in quality research productivity at the firm level is inversely related to patent quality and the level of demand as predicted by theory and patent quality is positively associated with the stock market value of firms
