how to best ensure remuneration for creators in the market for music copyright and its alternatives the focus of this essay is to examine the market for copyrighted works with a particular emphasis on the sound recording market this market is currently in a state of flux some would say disarray due to the ability of the internet to lower transmission costs for both authorized and unauthorized copies with the latter being at this time far more prevalent in this essay we discuss the intent of copyright the role of copying and file sharing and some alternative production consumption schemes meant to strengthen or to replace copyright

do labor market policies have displacement effects evidence from a clustered randomized experiment this article reports the results from a randomized experiment designed to evaluate the direct and indirect displacement impacts of job placement assistance on the labor market outcomes of young educated job seekers in france we use a two step design in the first step the proportions of job seekers to be assigned to treatment 0 25 50 75 or 100 were randomly drawn for each of the 235 labor markets e g cities participating in the experiment then in each labor market eligible job seekers were randomly assigned to the treatment following this proportion after eight months eligible unemployed youths who were assigned to the program were significantly more likely to have found a stable job than those who were not but these gains are transitory and they appear to have come partly at the expense of eligible workers who did not benefit from the program particularly in labor markets where they compete mainly with other educated workers and in weak labor markets overall the program seems to have had very little net benefits

the long run effects of unemployment monitoring and work search programs experimental evidence from the united kingdom this article examines the long run effects of the restart unemployment program in the united kingdom the program aimed at the long term unemployed involved a combination of tighter monitoring of benefit eligibility rules and increased job search assistance we compare the employment behavior of a treatment group who participated in the scheme with that of a randomly chosen control group for whom participation was delayed while there is little evidence of a long term benefit for women the unemployment rate among males in the treatment group was six percentage points lower than that of the control group 5 years after the initial experiment

journal pricing and mergers a portfolio approach despite their influence on the careers of economists the production and pricing of scholarly journals have received scant attention from the profession by contrast the issue of journal quality and scholarly research productivity have been studied in far greater detail a search in the econlit database using the term journal generates several dozen papers on this topic although there may be a number of reasons for this imbalance it is likely that the tenure process combined with the low if not zero effective cost of journals on campuses have influenced our research agenda in other words while professors worry about their job security publish well or perish others their librarians are charged with maintaining free access to all relevant journals of course this pattern is observed not just in economics but across academic disciplines in recent years however easy access to journals has been threatened beset by persistent journal price inflation especially in the socalled stm fields or science technology and medicine and stagnant budgets many university libraries have been forced to reallocate dollars from monographs to journals to postpone the purchase of new journal titles and in some cases to cancel titles as a consequence libraries often relied on interlibrary loans to satisfy faculty demands this situation and its possible causes has been studied at great length in the library science literature with few exceptions a consensus has evolved there which focuses on the growing importance of commercial publishers in the market for scholarly journals over the past decade or more commercial firms have aggressively raised prices at a rate disproportionate to any increase in costs or quality this appears to be especially true for the largest commercial firms although the analysis underlying these conclusions is generally not of the multivariate sort it is suggestive enough to warrant further investigation school of economics georgia institute of technology 781 marietta street nw atlanta ga 30318 e mail mark mccabe econ gatech edu i would like to thank many of my former colleagues at the department of justice including craig conrath renata hesse aaron hoag russ pittman david reitman dan rubinfeld and greg werden as well as jonathan baker cory capps george deltas luke froeb jeffrey mackie mason roger noll dan o brien richard quandt lars hendrik roller steve salop and margaret slade seminar participants at the federal trade commission georgia tech north carolina state university suny stony brook and wissenschaft zentrum berlin and participants at the meetings of the american economic association the european association of research in industrial economics the southern economics association and western economics association the association of research libraries and its members the national library of medicine the georgia tech library and the georgia tech foundation have provided invaluable assistance expert data support was provided by a large group of individuals including deena bernstein claude briggs pat finn doug heslep and steve stiglitz finally i would like to thank the dozens of librarians and publishers who have provided me with important insights 1 the exceptions are janusz a ordover and robert d willig 1978 lisa lieberman et al 1992 george a chressanthis and june d chressanthis 1994 mccabe 2000 and theodore c bergstrom 2001 ordover and willig model the pricing of a single title to institutional and individual subscribers bergstrom s paper discusses the differences between commercial and nonprofit economics journals the other three papers are discussed below 2 increasingly journals are available in both print and digital versions and for some new titles only a digital format is available see carol tenopir and donald king 2000 ch 15 starting in 1998 commercial publishers began placing their content online although major research libraries have generally responded by adding digital access this shift is still in its early stages especially in cases where library collections are more specialized e g the typical biomedical library for this reason as well as the fact that more than two thirds of the sample period occurred in a print only environment the emphasis of this paper is on the behavior of publishers and libraries in a print environment the economic implications of digital access are considered briefly at the conclusion of the paper and are a subject of ongoing research 3 see martha kyrillidou 1999 4 see tenopir and king 2000 ch 13 for a review of this literature an alternative explanation for journal price inflation has been offered by lieberman et al 1992 they argue that entry by new titles over time has lowered circulation for existing journals forcing the latter to raise prices to cover fixed costs

price discrimination copyright law and technological innovation evidence from the introduction of dvds u s copyright law effectively prevents direct price discrimination for copyright holders that sell to different markets in response these firms can engage in indirect price discrimination i derive theoretical predictions about the use of indirect price discrimination and i analyze how optimal pricing strategies differ for different products using data on vhs and dvd movie distribution i find that firms pricing choices are consistent with the predictions of theory and that firms use of indirect price discrimination benefits consumers but harms ancillary retailers finally i examine what optimal pricing strategies might look like in a legal environment that permits direct price discrimination

experimental evidence on unemployment insurance work search policies this paper describes findings from an experimental evaluation of alternative work search policies in the unemployment insurance ui program we find that the no work search treatment significantly increased ui receipt relative to the standard work search approach by 3 3 weeks and 265 per claimant and that the treatment with the most intensive requirements reduced ui payments by one half of a week or 70 per claimant the results suggest that work search requirements reduce ui spells by increasing the nonmonetary costs of remaining on ui rather than enhancing job search abilities we also find little treatment effects for wages earnings or total income suggesting that an increase in the nonmonetary costs of continued ui receipt are associated with more intensive job search rather than a reduction in the reservation wage

digital content provision and optimal copyright protection advances in digital technologies have led to an increasing concern about piracy for providers of digital content e g e books games music software videos yet controversies exist over the influence of copyright protection on firm profitability the objective of this paper is to provide an alternative rationale for the growing anti protection trend and to investigate optimal copyright enforcement and quality provision in a monopoly setting the proposed economic mechanism centers on the influence of copyright protection on consumer search when consumers can get to know the firm s actions e g price quality only after costly search we show that more stringent copyright protection can induce the consumers to rationally expect lower ex post surplus thus exerting a negative strategic effect on the consumers willingness to search this strategic effect may outweigh the positive main effect on the relative attractiveness of the authorized versus the pirated product which can hence explain the opti

does a minimum job search requirement reduce time on unemployment payments evidence from the jobseeker diary in australia this study examines the impact of thejobseeker diary jsd a program designed to increase the job search effort of unemployed persons in australia the jsd program is distinguished by combining a focus on work search verification with large scale imple mentation applying a quasi experimental matching method to data on unemployment spells occurring in 1997 98 the authors find that jsd participation was associated with an increased rate of exit from unemployment payment recipiency and a shorter total time spent on payments payment receipt duration is estimated to have fallen for about one half of jsd participants the largest effects of the jsd occurred for payment recipients for whom labor demand conditions were the most favorable cost benefit analysis suggests a fairly large net societal gain per program participant this study examines a large scale interven tion intended to increase job search ef fort of unemployed persons in australia the intervention the jobseeker diary jsd is a work search verification program that re quires unemployment payment recipients to complete a fortnightly biweekly diary in which details of a specified minimum number of job applications must be recorded the scale of the jsd program and its focus on work search verification make it unique in the international context

further reflections on hidden unemployment an examination of the off flows from the claimant count in the north west of england one of the most significant set of papers to come out of the portfolio of regional studies association publications in recent years has concerned the exposure of the levels of hidden unemployment in many of the old industrial areas of britain see for instance labour market adjustment in areas of chronic industrial decline the case of the uk coalfields regional studies 30 7 1997 627 640 the authors of these papers christina beatty and stephen fothergill have generated a debate that has uncovered major implications for the way the regional problem is measured perceived and tackled although these are important in terms of regional economic development strategies and policies it remains to be seen how the failure to count the real levels of unemployment will impact on the review of regional policy assisted areas the designation of european structural fund areas and the successful introduction of such initiatives as the new deal and welfare to work underpinning and deepening the rigour of t

software piracy an analysis of protection strategies software piracy by users is generally believed to harm both software firms through lower profits and buying customers through higher prices thus it is thought that perfect and costless technological protection would benefit both firms and consumers the model developed here suggests that in some circumstances even with significant piracy not protecting can be the best policy both raising firm profits and lowering selling prices key to the analysis is joining the presence of a positive network externality with the fact that piracy increases the total number of program users the network externality exists because consumers have an incentive to economize on post purchase learning and customization costs

copyright protection standards and authors time allocation for centuries it was necessary for performers to be present in real time to supply their services such as music dance or drama labor time and human skill and capital were inextricably related reproducibility the ability to make copies of human services that are adequate substitutes for live performance has meant performers need not be present to supply their services which can be recorded and supplied with economies of scale consumers do not need the live performer to be present to obtain their services demand for performers has therefore fallen the same is of course true for non performing authors such a scenario must have altered the balance of incentives for authors for how they ultimately decide to spend their time the choices between working on producing copyrighted material which will earn them income through royalties over the duration of the copyright working for spot wages either in related or in unrelated activities and to take leisure must be closely related to the ability of copyright law to guarantee future income from copyrights this article considers this situation in terms of a formal model of time allocation copyright 2006 oxford university press

punitive sanctions and the transition rate from welfare to work in the netherlands the average exit rate out of welfare is dramatically low most welfare recipients have to comply with guidelines on job search effort that are imposed by the welfare agency if they do not then a sanction in the form of a temporary benefit reduction can be imposed this article investigates the effect of such sanctions on the transition rate from welfare to work using a unique set of rich register data on welfare recipients we find that the imposition of sanctions substantially increases the individual transition rate from welfare to work

is unemployment really scarring effects of unemployment experiences on wages joblessness leaves permanent scars on individuals they not only lose income during periods of joblessness they are also further scarred by these experiences when they find employment a spell of unemployment is found to carry a wage penalty of about 6 on re entry in britain and after three years they are earning 14 less compared to what they would have received in the absence of unemployment the scars are also carried into their second employment spell the first spell of joblessness is found to cause the most damage redundancy seems to be less stigmatising

an introduction to the law and economics of intellectual property although economists have written on topics of intellectual property for a long time the impact of economics on public policy in this area has been slight especially as compared to the influence of professional writings in areas such as antitrust and taxation we believe that too few of the profession s resources have been devoted to these issues and that of those resources that have been employed too few have been devoted to empirical analyses we hope that this introductory essay and the three papers that follow will stimulate interest in this subject this introductory essay first describes some of the basic economic tradeoffs involved in intellectual property law and then describes the framework of the law in the six areas described above patent copyright semiconductor protection trademark trade secret and misappropriation it is intended both to provide thumbnail descriptions of the various intellectual property regimes to economists working in this area and to indicate where additional economic research might be useful

the effect of unemployment insurance sanctions on the transition rate from unemployment to employment sanctions or punitive benefits reductions are increasingly used as a tool to enforce compliance of unemployment insurance claimants with search requirements this article analyses sanctions using a unique administrative data set of individuals who started collecting unemployment insurance in the netherlands in 1992 after correction for selectivity in the imposition of sanctions we find that sanctions substantially raise individual re employment rates

the long term effects of job search requirements evidence from the uk jsa reform this paper investigates long term returns from unemployment compensation exploiting variation from the uk jsa reform of 1996 which implied a major increase in job search requirements for eligibility and in the related administrative hurdle search theory predicts that such changes should raise the proportion of non claimant nonemployed with consequences on search effort and labor market attachment and lower the reservation wage of the unemployed with negative effects on post unemployment wages i test these ideas on longitudinal data from social security records llmdb using a difference in differences approach i find that individuals who start an unemployment spell soon after jsa introduction as opposed to six months earlier are 2 5 3 more likely to move from unemployment into incapacity benefits spells and 4 5 less likely to have positive earnings in the following year this latter employment effect only vanishes four years after the initial unemployment shock also annual earnings for the treated individuals are lower than for the non treated these results suggest that while tighter search requirements were successful in moving individuals off unemployment benefits they were not successful in moving them onto long lasting or better jobs with fairly long lasting unintended consequences on a number of labor market outcomes

price discrimination in the subscription market for economics journals author affiliation yuqing zheng yuqzheng rti orgharry m kaiser hmk2 cornell edu acknowledgment this research was conducted when dr zheng was working as a research associate at the dyson school of applied economics and management of cornell university 1 introductionmost scientific journals charge a higher subscription price to institutional subscribers and a lower subscription price to individual subscribers such practice is often considered an issue of third degree price discrimination in the economics and library literature e g liebowitz 1985 phillips and phillips 2002 1 this article examines what factors affect the degree of price discrimination for an academic journal by analyzing data on 190 of the 208 economics journals indexed in the 2008 edition of journal citation reports compiled by the institute for scientific information jcr economics journals hereafter 2 the empirical literature on price discrimination in the market for journals is very limited we attempt to enrich this existing literature by providing insights primarily in the following three aspects price discrimination by journal governance for profit vs nonprofit status by publisher and by how the differences in journal pricing behavior in the respective library and individual markets lead to various degrees of price discrimination first it is well known that for profit journals fp journals often charge significantly higher library subscription prices than do comparable nonprofit journals nfp journals many studies have reported a price premium charged by fp journals e g bergstrom s 2001 study on economics journals and the study conducted by dewatripont et al 2007 on 22 fields of natural and social sciences what is less known is whether a fp journal is more discriminatory than a nfp journal that is the ratio of the price charged to libraries over that charged to individuals the library to individual price ratio henceforth could be higher for a fp journal than for a comparable nfp journal take the jcr economics journals in our data as an example we plot in figures 1 and 2 a journal s library to individual price ratio against its impact factor with figure 1 representing fp journals and figure 2 representing nfp journals for the 105 fp journals in our sample the average library to individual price ratio is 8 16 with a price ratio of 34 58 the champion goes to the journal of economic theory for the 85 nfp journals in the data the average and maximum library to individual price ratios are 4 13 and 14 03 respectively with the latter belonging to fiscal studies in this article after controlling for other factors affecting pricing behavior by publishers we examine whether the degree of price discrimination differs depending on whether a journal is fp or nfp as suggested in the two figures our results indicate that fp journals are more discriminatory indeed figure 1the library to individual price ratios for for profit journals n 105 figure omitted see article image figure 2the library to individual price ratios for nonprofit journals n 85 figure omitted see article image second we identify publisher heterogeneity in engaging in price discrimination which is informative to the library and academic communities but not known in the literature for jcr economics journals the major publishers include the four major commercial publishers elsevier wiley blackwell springer and taylor francis including routledge as well as various university presses and associations societies we allow for publisher conduct heterogeneity in conducting price discrimination and find that elsevier is the most discriminatory publisher among all groups followed by wiley blackwell third in addition to the library to individual price ratio the library price and individual price are estimated respectively

a simulation study of the interactive effects of taxes and inflation on the relative price of land recent experience in the united states with high and variable inflation has led to an outpouring of research concerning inflation s impact on the relative prices of real and financial assets with the exception of three recent papers feldstein 1980a rose 1986a alston 1986 the impact of inflation on the relative price of land has been neglected land is usually eliminated from economic models of the tax system so that the effects of inflation s complex interaction with the income tax system on firm financing and valuation of capital can be highlighted in this paper we take the opposite approach the effects of inflation on corporate financing of capital are suppressed by allowing only bond financing in order to highlight the effects of inflation and tax rate changes on the relative price of land

housing price land supply and revenue from land sales in a recent study peng and wheaton empirically examine the effect of restrictive land supply on hong kong house prices however we argue that the impact of the supply of new land by the hong kong government is not as important as they maintain in accounting for the volatile house prices in hong kong we show that there is no causal relationship between land supply and housing prices our estimations based on the annual data of hong kong s public land sales find that the government acts to maximise land revenue maximisation of revenue from land sales is however consistent with the efficient allocation of resources we also show that the amount of land sales by the government and land in developers land banks tend to decrease when market interest rates increase land banking behaviour is governed by economic conditions long term land holding costs should cover interest costs

digital piracy a competitive analysis in recent years the issue of copyright protection for intellectual properties such as computer software music cds and videos has become increasingly important it is often claimed that illegal copying of intellectual property costs companies billions of dollars in lost revenues and reduces firms incentives to innovate some researchers have shown that copying can be beneficial to firms when there are strong network effects and copying expands the market in this paper we first examine the impact of illegal copying of software and other similar intellectual properties on firms prices profits and quality choices even when there are no network effects and the market is saturated we show that contrary to the claims of manufacturers there are conditions under which copying can increase firms profits lead to better quality products and increase social welfare this is because weaker copyright protection enables firms to reduce price competition by allowing price sensitive consumers to copy thus weaker copyright protection can serve as a coordination device to reduce price competition we also examine how equilibrium copyright enforcement is affected by network externalities in contrast to previous research we show that strong network effects can sometimes lead to a firm choosing higher levels of copyright protection our results show that in the presence of strong network effects stronger copyright enforcement by one firm can serve as a coordinating device to reduce price competition

optimal strategic pricing of reproducible consumer products this paper investigates the strategic pricing of consumer durable products which can be acquired through either purchase or reproduction e g computer software as copy piracy results in an opportunity loss its adverse effect on profits needs to be incorporated in strategic decisions such as pricing using a dual diffusion model which parsimoniously describes sales and copying and employing control theory methodology optimal price trajectories are derived for the period of monopoly the results indicate that a in absence of any protection skimming pricing strategies are generally optimal and b copy protection is warranted only when sales diffuse much faster than copying and the protection technology does not significantly raise the marginal production cost

the effects of anticipated inflation on housing market equilibrium an increase in the anticipated rate of inflation causes distortions in the housing market due to a nonindexed tax system since nominal rather than real interest payments are tax deductible an increase in inflation decreases the aftertax cost of capital for homeowners which in turn increases the demand for housing and increases its real price this tax gain is shown to be larger for rental housing than for owner occupied housing in a competitive market this implies that although the real price of housing increases with a rise in anticipated inflation real rental rates fall in the last decade the real price of corporate capital fell while the price of housing increased dramatically during this same period the rate of inflation increased substantially empirical studies have found a negative relationship between stock returns and the inflation rate 1 while housing has been found to have been a good hedge against inflation 2 tax distortions related to the change in the rate of inflation provide one popular explanation for the negative relationship between stock prices and inflation 3 the effect of similar tax induced distortions on the equilibrium in the housing market will be studied in this paper it is shown that the real price of housing increases with the anticipated rate of inflation while the real rental rate declines these results are consistent with published data for the period 1967 77 during which the anticipated rate of inflation increased substantially 4 the general price level as measured by the consumer price index increased 81 5 percent between 1967 and 1977 5 in this

multiproduct equilibrium price dispersion abstract the model of burdett and judd econometrica51 1993 955 969 is generalized to the case of may goods consumers choose the best price observed for each good there are two classes of equilibria those that involve constant expected profits for each good independently of price and those with increasing profits for each good in price a continuum of the latter type always exists these equilibria are qualitatively different than the unique equilibrium of the single good case journal of economic literature classification numbers d83 d43 l13

housing market equilibrium almost without vacancies the swiss housing market is characterised by an extraordinarily low vacancy rate generally in the vicinity of 1 per cent is the swiss housing market permanently in a condition of severe shortage this paper uses both a standard non accelerating rent inflation rate of vacancy approach and a new perception based approach to answer this question the available evidence confirms that a vacancy rate of 1 1 5 per cent is indeed sufficient for the swiss housing market to be in equilibrium provided only dwellings that are not only unoccupied but also actually offered for rent or purchase are counted which makes this rate not easily comparable with other countries the standard equilibrium vacancy rate approach suggests that even lower rates are sufficient in more densely built places whereas the approach based on perceptions makes no difference this suggests that the dwellings listed by people who wish to move reduce the pressure on rents but not the feeling of housing shortage

the intertemporal consequences of unauthorized reproduction of intellectual property in an intertemporal framework the harm to firms from unauthorized reproduction of their products may be significantly greater than that predicted by most static models copying by some consumers reduces the appropriable surplus from all consumers including those consumers lacking any propensity to copy somewhat paradoxically however the commitment value of copies may also imply that profits are higher with copying than without copying it is therefore suggested that firms may prefer differential copyright enforcement and that the commitment value of copies may offer a strategic explanation for free giveaways of abridged versions of intellectual property and vertical product differentiation more generally

the effects of increased copyright protection an analytic approach previous authors who have considered partially nonexcludable goods have claimed that an increase in copyright protection will have the following two effects on social welfare first it will decrease the social welfare loss due to underproduction second it will increase the social welfare loss due to underutilization in this paper we investigate these claims in a formal setting by analyzing a model in which consumers vary only in terms of their costs of obtaining a reproduction our analysis provides partial support to the first claim of these previous authors while giving little or no support to the second claim

unemployment insurance recall expectations and unemployment outcomes this paper empirically examines the importance of explicitly accounting for the layoff rehire process in the analysis of unemployment outcomes in the united states we find that the spells of individuals who initially expect to be recalled account for much more of the unemployment of unemployment insurance ui recipients than do spells actually ending in recall our results indicate that the recall and new job escape rates from unemployment have quite different time patterns and are often affected in opposite ways by explanatory variables we also find that the probability of leaving unemployment both through recalls and new job finding increases greatly around the time that ui benefits lapse over the past fifteen years many studies have empirically analyzed the determinants of individual unemployment spell durations in the united states much of this literature has used a job search framework in which the unemployed are viewed as permanently displaced workers who are unattached to jobs the possibility of recall to a former job a process not requiring search has been omitted from explicit consideration in the majority of these studies 2 an explicit treatment of the layoff rehire process is necessary for a proper understanding of the determinants of unemployment durations and of the impacts of unemployment policies in the united states for at least three reasons first temporary layoffs in which workers are often rehired by their original employers are a quantitatively quite important feature of the u s labor market 3 second expectations concerning the likelihood of recall are likely to affect the responses of employers and unemployed workers to labor market interventions such as reemployment bonuses and subsidies

activating unemployed workers works experimental evidence from denmark abstract in a field experiment in two danish counties about half of the unemployed workers were randomly assigned to a mandatory activation program analyzing data from this experiment we show that activation can be very effective in reducing unemployment durations

innovation imitation and social welfare this paper focuses on the impact of competition by imitation more specifically copying for innovative activity and social welfare in part it is a response to recent empirical work 10 12 that has tried to measure the relationship between innovation and imitation costs these papers include a direct call for theoretical modeling that takes explicit account of such cost relationships and we try to answer this challenge specifically we examine the implications for product quality and social welfare when innovators anticipate that a successful product will be copied by rivals obviously previous empirical research is not the only source of interest in these issues the potential effects of imitation on innovative activity have long been both a theoretical and practical concern in recent years a variety of authors have addressed the appropriability issue raised by imitation and its implications for innovative activity 4 7 2 there has also been work on explicit copying i e photocopying 8 11 in the policy arena the protection of product design and intellectual property rights is the focus of much recent actual and proposed u s legislation and a major issue in the uruguay round of trade talks 1 21 our analysis of this topic differs from that of previous work in a number of important respects first we focus explicitly on product as opposed to process innovations second and perhaps even more important we do not restrict the firm s choice to be to innovate or not to innovate instead we allow the innovator to choose what kind or quality of new good to introduce into the market the higher the quality the higher is the development cost third when the innovating firm decides what kind of new product to market it does so under uncertainty about demand the popularity of the new product is not known until after the innovator has chosen the level of quality and sunk its product development costs fourth at the initial time at which the innovator chooses the quality of product to develop it does so with the knowledge that its innovation if it is popular will be copied by later rival entrants finally in direct response to the empirical work mentioned above we explicitly focus on the ratio of imitation to innovation costs our approach yields a number of insights not the least of which is a more precise identification of the potential gains and losses from imitative competition indeed using a quadratic development cost function we explicitly calculate the impact of copying on social welfare this explicit welfare analysis further distinguishes our analysis from most previous work

price discrimination of digital content abstract this paper considers the simplest drm which permits either free or no copying with incomplete information about the type of consumer we first obtain results concerning separability of consumers in a general situation and show that there is a critical type of consumer a higher utility type selects a menu of free copying whereas a lower one chooses not to copy in a two type model we indicate that optimal pricing for a producer is different from that under two part tariffs this price strategy brings about greater profits and social welfare if and only if self production is more efficient than that of a producer

fighting software piracy which governance tools matter in africa this article integrates previously missing components of government quality into the governance piracy nexus in exploring governance mechanisms by which global obligations for the treatment of iprs are effectively transmitted from international to the national level in the battle against piracy it assesses the best governance tools in the fight against piracy and upholding of intellectual property rights iprs the instrumentality of ipr laws treaties in tackling piracy through good governance mechanisms is also examined findings demonstrate that 1 while all governance tools under consideration significantly decrease the incidence of piracy corruption control is the most effective weapon 2 but for voice and accountability political stability and democracy ipr laws treaties are instrumental in tackling piracy through government quality dynamics of rule of law regulation quality government effectiveness corruption control and press freedom hence the need for a policy approach most conducive to expanding development is to implement an integrated system of both iprs and corollary good governance policies moreover our findings support the relevance of good governance measures in developing countries wishing to complement their emerging ipr regimes

an econometric analysis of reservation wages this paper describes an analysis of survey data on unemployed people who reported their asking wage and the wage they expected to earn we show that if agents behavior is described by the standard optimal job search model one can use these data to deduce structural parameters rather than estimate them and we report our deductions from two surveys 1 of british unemployed people

do geographical mobility requirements for the unemployed affect their exit rate to work evidence from a policy change a policy change tightened job search requirements regarding geographical mobility for unemployment insurance benefit recipients in germany those affected by the policy change were individuals without family ties and whose reemployment prospects were low in their home labor market region the author finds that after one year the policy change led to a 4 6 percentage point increase in employment among women without children who lived in regions with relatively high unemployment women responded to the policy change by taking up jobs in their home labor market region as well as outside of that region the author does not find any effects of the tightened mobility requirements for men

which is a better investment choice in the hong kong residential property market a big or small property the relationship between property size and property investment yield is an interesting issue in the real estate market previous studies usually use the mean variance criterion to compare the return risk profiles of the yields of different property sizes in the united states however this criterion has a few shortcomings this article provides the first attempt to use a stochastic dominance approach to analyse this issue we adopt two powerful stochastic dominance tests to compare the yields of five property size classes in the hong kong residential property market in our study we analyse two possible investment outcomes 1 investors could not rent out their properties and thus they would gain lose from the appreciation depreciation of residential property prices 2 investors could also gain from rental incomes our empirical results provide strong evidence to show that the yields of smaller property classes stochastically dominate the yields of bigger property classes suggesting that buying smal

does job search monitoring intensity affect unemployment evidence from northern ireland because unemployment benefit reforms typically package together a number of changes few existing evaluations have been able to isolate the effects of changes in job search monitoring intensity on benefit recipient stocks or flows those few studies that do so draw mixed conclusions this paper provides new estimates of monitoring impacts by exploiting plausibly exogenous periods where search monitoring has been temporarily withdrawn with the regime otherwise unchanged during a series of benefit office refurbishments in northern ireland as we would expect from search theory withdrawal of monitoring significantly increases the stock of unemployment benefit recipients via reduced outflows

the internationalisation of public welfare policy with increasing globalisation of knowledge there are increased opportunities to learn from the experience of policy interventions elsewhere this paper presents evidence on the extent of international convergence in public policy with particular focus on labour welfare savings and retirement policy questions addressed in this framework include to what extent is policy diffusion or convergence a real and relevant phenomenon what role have economists played in the transfer of policy across national domains has policy transfer led to better public policy are there any practical limitations to policy convergence

the slowdown in first response times of economics journals can it be beneficial the first response time henceforth frt of economics journals has increased over the last four decades from 1 2 months to 3 6 months the optimal frt however is not zero because the frt deters submission of mediocre papers to good journals and consequently saves valuable time of referees and editors the change in the actual frt is in the same direction as the change in the optimal frt which has increased because of the availability of research on the internet prior to publication and because the costs of refereeing a paper have increased

experimental evidence on the effects of early meetings and activation we analyze the effects of four randomized social experiments involving early and intensive active labour market policy conducted in denmark in 2008 the experiments entailed different combinations of early and intensive treatment in terms of meetings and active labour market programmes we find that frequent meetings between newly unemployed workers and case workers can increase employment rates over the next two years by up to 10 weeks the effects continue to grow over the whole 4 year horizon studied for men we find evidence of a threat effect of having to participate in early active labour market programmes while no such effect is found for women we conduct a cost benefit analysis of each ofthe four experiments and find that meetings yield the largest net benefits

dead poet s property how does copyright influence price copyrights create long lived intellectual property in goods ranging from science literature and music to news film and software the economic effects of copyright however are difficult to identify in modern settings this article exploits an unintended differential increase in copyright length under the uk copyright act of 1814 in favor of books by dead authors to examine the effects of longer copyright terms on price we find that a doubling in copyright length was associated with a substantial roughly 50 increase in the price of books additional years of copyright improved publishers ability to practice intertemporal price discrimination

incentive to reduce crop trait durability to reduce the competition from farmers who self produce seed an inbred line seed producer can switch to nondurable hybrid seed in a two period model we investigate the impact of crop durability on self production pricing and switching decisions and we examine the impact of license fees paid by self producing farmers first in an inbred line seed monopoly model we find that the monopolist may produce technologically dominated hybrid seed in order to extract more surplus from farmers further the introduction of license fees improves efficiency second we study how the monopolist s behavior is affected by the entry of a nondurable hybrid seed producer we show that the inbred line seed producer might benefit from competing with a technologically dominated hybrid seed producer as this allows for consumers discrimination

is the threat of reemployment services more effective than the services themselves evidence from random assignment in the ui system we examine the effect of the worker profiling and reemployment services system this program profiles unemployment insurance ui claimants to determine their probability of benefit exhaustion and then provides mandatory employment and training services to claimants with high predicted probabilities using a unique experimental design we estimate that the program reduces mean weeks of ui benefit receipt by about 2 2 weeks reduces mean ui benefits received by about 143 ana increases subsequent earnings by over 1 050 most of the effect results from a sharp increase in early ui exits in the treatment group relative to the control group jel j650

evaluating the econometric evaluations of training programs with experimental data this paper takes the results of an employment and training program thatwas run as a field experiment in which the participants were randomlyassigned into a treatment or a control group and compares these results to the estimates that might have been produced by an econometrician who evaluated the program using the same econometric procedures that have been used in the program evaluation literature this comparison shows that many of these econometric procedures fail toreplicate the experimentally determined results and suggests that researchers should be aware of the potential for specification errorsin other nonexperimental evaluations copyright 1986 by american economic association

how to help unemployed find jobs quickly experimental evidence from a mandatory activation program abstract this paper investigates how a mandatory activation program in denmark affects the job finding rate of unemployed workers the activation program was introduced in an experimental setting where about half of the workers who became unemployed in the period from november 2005 to march 2006 were randomly assigned to the program while the other half was not it appears that the activation program is very effective the median unemployment duration of the control group is 14 weeks while it is 11 5 weeks for the treatment group the analysis shows that the job finding rate in the treatment group is 30 higher than in the control group this result is mainly driven by the more intensive contacts between the unemployed and the public employment service

buying sharing and renting information goods information goods such as books journals computer software music and videos can be copied shared resold or rented when such opportunities for sharing are present the content producer will generally sell a smaller amount at a higher price which may increase or decrease profits i identify three circumstances where profits increase 1 when the transactions cost of sharing is less than the marginal cost of production 2 when content is viewed only a few times and transactions costs of sharing are low and 3 when a sharing market provides a way to segment high value and low value users

reconnecting the long term unemployed to labour market opportunity the case for a local active labour market policy campbell m 2000 reconnecting the long term unemployed to labour market opportunity the case for a local active labour market policy reg studies 34 655 668 this paper argues that the development of a local active labour market policy can make a valuable contribution to reconnecting the long term unemployed to labour market opportunities such an approach is broadly consistent with the evolving eu and uk government policy agendas but it is argued the content and nature of local action needs to be informed by a sound understanding of the causes of long term unemployment and the lessons that can be learnt from studies of the effectiveness of previous active labour market policy interventions at national and local level a strategic framework is proposed which can be used as a means of examining current policy and as an approach to developing local policy campbell m 2000 reintegrer les chomeurs de longue duree dans le marchedu travail pour une politique en faveur d un marchedu travail actif

earnings unemployment and the allocation of time over time since an individual s labour market history can be described by a markov chain in state space it is possible to calculate the steady states it is natural to interpret the steady state proportion in unemployment for a group of identical workers as the natural rate of unemployment for this group i e it is the expected proportion that would be employed if the environment were to remain constant it is shown how the natural rate of unemployment is different for different groups the model is estimated using data from a large u s income maintenance experiment the predictions of the model with some exceptions bear up well to confrontation by data the empirical findings also accord well with existing evidence on cross section studies of labour supply we find that labour force participation rates implied by the estimated models are positively related to earnings for all age sex and race groups as expected we demonstrate that the elasticities of the unemployment rates for all groups with respect to expected wage rates are negative and large in absolute value in the case of adults while the role of the wage in allocation of time is not novel the existing neoclassical labour literature uses static labour supply models to interpret participation rate studies

estimating equilibrium effects of job search assistance identifying policy relevant treatment effects from randomized experiments requires the absence of spillovers between participants and nonparticipants sutva or variation in observed treatment levels we find that sutva is violated for a danish activation program for unemployed workers using a difference in differences model we show that nonparticipants in the experiment regions find jobs more slowly after the introduction of the program than workers

measuring the equilibrium effects of unemployment benefits dispersion we analyze the impact of unemployment benefits and minimum wagesusing an equilibrium search model which allows for dispersion ofbenefits and productivity levels job to job transitions andstructural and frictional unemployment the estimation method usesreadily available aggregate data on marginal distributions ofunemployment durations as well as wages and benefit levels different causes of structural and frictional unemployment areinvestigated we investigate the efficiency of the imposition of asingle benefit level for all household types and the introductionof an earned income tax credit

hedonic prices and contractual contingencies abstract hedonic models are widely used to analyze markets for differentiated goods this paper examines the appropriate specification of characteristics to be included in the hedonic price function we develop a model that shows that the characteristics of the contract used to transfer a good from the buyer to the seller should also be included in the price function and present an empirical application of the model using data for single family house transactions the results indicate that the market exacts a price for the uncertainties created by contractual contingencies in the way described by the model

collection sales good or bad for journals this paper discusses the impact of collection sales i e the bundling of several journals for sale by publishers to libraries on journals the advent of electronic journal distribution implies that bundling is an efficient sales strategy and can act to extend the reach of a journal current arrangements are discussed and shown to lead to tensions between commercial publishers and non profit journals the paper argues that non profit journals should not necessarily abandon collection sales programmes rather non profit journals may benefit from withdrawing from commercial publishers which distribute their own for profit journals and joining together to be distributed by less commercial publishers who set relatively low prices for their collections

free labor for costly journals there is a remarkable difference between the prices that commercial publishers charge to libraries for economics journals and the prices charged by professional societies and university presses this price difference does not reflect a difference in quality the six most cited economics journals listed in the social science citation index are all nonprofit journals and their library subscription prices average about 180 per year only five of the 20 most cited journals are owned by commercial publishers and the average price of these five journals is about 1660 per year tables 1 and 2 compare library costs and measures of cost effectiveness for the ten most cited nonprofit journals and the ten most cited journals owned by commercial presses the average price per page of the commercial journals is about six times as high and the average price per citation is about 16 times as high as for the nonprofit journals in tables 1 and 2 the first column shows the year 2001 library subscription price and the second column shows the price per page calculated by dividing year 2001 price by the number of pages published in the year 2000 the third column reports the price per citation this is the library subscription price divided by the number of times that articles in this journal were cited in 1998 as recorded by the social science citation index the fourth column price per recent citation is the library subscription price divided by the number of times that the 1996 and 1997 volumes of the journal were cited in 1998 the citation rank is found by ranking journals according to the number of times that this journal was cited in 1998 the differences in prices and cost effectiveness between nonprofit and commercial journals are similar for less prestigious journals i have assembled a data

flexible parametric estimation of duration and competing risk models in this paper we specify and estimate a flexible parametric proportional hazards model the model specification is flexibly parametric in the sense that the baseline hazard is non parametric while the effect of the covariates takes a particular functional form we also add parametric heterogeneity to the underlying hazard model specification we specify a flexible parametric proportional competing risks model which permits unrestricted correlation among the risks unemployment duration data are then analysed using the flexible parametric duration and competing risks specifications we find an important effect arising from the exhaustion of unemployment insurance and significantly different hazards for the two types of risks new jobs and recalls

the welfare implications of unauthorized reproduction of intellectual property in the presence of demand network externalities this paper finds that unauthorized reproduction of intellectual property in the presence of demand network externalities can not only induce greater firm profits relative to the case where there is no copying it can lead to a pareto improvement in social welfare ceteris paribus when network externalities are present firms have a greater incentive to expand output because marginal revenue is higher and or they may wish to create preemptive installed bases this paper suggests that unauthorized copying can be a relatively efficient means of achieving this by allowing the firm in effect to price discriminate among different classes of consumers copyright 1994 by blackwell publishing ltd

unemployment duration and the restart effect some experimental evidence in this paper we analyse the effect of ihe restart programme in the united kingdom this programme consisis of an interview of tbe long term unemployed to counsel them on effective job search failure to attend the interview carries the threat of the cessation of unemployment benefits the results using experimental data indicate that the programme has a significant effect of reducing unemployment duration estimation of an independent competing risks model distinguishing between exits from unemployment to a job a training placement or to signing off unemployment benefit shows that the channels through which restart works differs according to exit type

housing vacancy and rental adjustment evidence from hong kong the traditional rental adjustment equation is flawed in that the equilibrium paths for the adjustment of rents and vacancy rates cannot hold simultaneously over time this paper suggests a two equation model of rental adjustments based on adaptive expectations rather than the single equation model presented in the traditional literature and provides empirical tests annual data from the housing market in hong kong during the 1980 96 period are consistent with the adjustment equation the results also show that the rate of change of real rents is neutral with respect to inflation

copying and indirect appropriability photocopying of journals creators and owners of intellectual properties are alarmed by the growth of technologies that ease the tasks of copying these properties this paper however shows that the unauthorized copying of intellectual properties need not be harmful and actually may be beneficial the empirical impact of photocopying on publishers of journals is examined in an attempt to discover if publishers can indirectly appropriate revenues from users who are not original purchasers the evidence indicates that publishers can indirectly appropriate revenues from users who do not directly purchase journals and that photocopying has not harmed journal publishers 18 references 1 table

unemployment insurance and unemployment spells this paper tests the effects of the level and length of unemployment insurance benefits on unemployment durations the paper particularly studies individual behavior during the weeks just prior to when benefits lapse higher unemployment insurance benefits are found to have a strong negative effect on the probability of leaving unemployment however the probability of leaving unemployment rises dramatically just prior to when benefits lapse individual data are used with accurate information of spell durations and the level and length of benefits the semiparametric estimation techniques used in the paper yield more plausible estimates than conventional approaches and provide useful diagnostics copyright 1990 by the econometric society

on publication refereeing and working hard we present a model for academia with heterogeneous author types and endogenous effort to evaluate recent changes in the publication process in economics we analyze the implications of these developments on research output lowering the precision of refereeing signals lowers the effort choices of intermediate ability authors but invites more submissions from less able authors increasing the number of journals stimulates less able authors to submit their papers the editor can improve the journal s quality pool of submitted manuscripts by improving the precision of refereeing but not by lowering acceptance standards the submission strategy of an author is informative of his ability

does inflation affect real behavior the case of housing an important tradition in economics is to assume that demand depends upon relative prices and is homogenous of degree zero for the most part this has been interpreted as meaning inflation changes in the price level leaves demand unchanged recent work by a number of economists has challenged this position for the case of housing demand two arguments have been made that inflation acting in concert with existing institutions alters the quantity of housing demanded and the decision to rent or own a house the first argument states that inflation and the standard fixed payment mortgage combine to reduce the size of the mortgage loan a household can obtain for the purpose of buying a home this works to reduce the quantity of owner occupied housing demanded given the importance of mortgage finance to the demand for owner occupied housing the second argument focuses on the inflation adjusted after tax cost of owner occupied housing it simply states that an increase in the rate of anticipated inflation of the general price level reduces the after tax cost of housing thus increasing the demand for housing and the demand for homeownership there has been little empirical testing of these two arguments the purpose of this paper is to formulate and estimate a model which will give an indication of the quantitative significance of the two arguments a housing demand equation and a tenure choice equation own versus rent are estimated using a sample of about 6000 households from the 1975 annual housing survey 10 the estimates suggest that inflation dampens housing demand and homeownership opportunity for most households even though the inflation adjusted after tax cost of owner occupied housing declines as inflation heats up the paper consists of six sections including the introduction section two examines the ways inflation affects housing choices in more detail the third section contains the specification of the econometric model that forms the basis of the study section four is a discussion of econometric problems and the data used the results of the estimates are discussed in the fifth section the paper concludes with a presentation of the major conclusions and policy implications of the study

willful blindness the inefficient reward structure in academic research this article examines how economics departments judge research articles and assign credit to authors it begins with a demonstration that only strictly prorated author credit induces researchers to choose e cient sized teams nevertheless survey evidence reveals that most economics departments only partially prorate authorship credit implying excessive coauthorship indeed a half century increase in coauthorship may be better explained by incomplete proration than by any increased specialization among authors a possible explanation for the reliance on incomplete proration is the self interest of economists who are more likely to engage coauthorship full professors the self interest of senior faculty may also explain the relatively small role given to citations in senior promotions a rational response by economists to the under proration of author credit is to engage in false authorship although false authorship is of dubious ethical status it may have the perverse impact of improving the e ciency of team production grossly excessive coauthorship where little attention is paid to most authors listed on a paper as found in some other academic disciplines may be the path down which economics is headed if the reward structure is not altered jel a14 o30 i23

inflation taxes and housing a theoretical analysis abstract this paper examines the real effects of inflation under a distortionary tax system the presence of a tax subsidy to housing substantially alters the effects of inflation on the capital intensity of production and on the market interest rate the analysis suggests that not taxing the flow of services from housing has caused inflation to reduce capital intensity thereby decreasing u s productivity furthermore this tax subsidy has caused inflation to raise the real interest rate while reducing the after tax real returns to assets

the economics of copyright fair use in a networked world the recent success of file sharing technologies such as napster has highlighted the economic question of whether copying increases or decreases the market value of copyrighted works contrary to michele boldrin and david k levine 2002 we show that napster type services are likely to reduce copyright value this economic question of the effect of copying on copyright value largely coincides with the legal question of whether copying is fair use the primary legal determinant of fair use or use that does not require authorization by the copyright holder is whether the use adversely affects the present or future economic value of the copyrighted work 1 however given this legal standard it is unclear why copyright holders ever disagree with the court regarding fair use our analysis shows that there is no inherent conflict between the court and copyrightholders with regard to particular uses but why there may be a conflict with regard to a technology that has both fair and infringing uses

unemployment duration and individual heterogeneity a regional study this paper investigates the impact of individual heterogeneity and regional influences on unemployment duration utilizing cross section microeconomic data drawn from a representative random survey of individual job seekers for the english county of kent these individual level data are unique in that they provide information concerning the personal characteristics of job seekers alongside direct observations of both their reservation wages and job search behaviour such data are rare and to the authors knowledge have never before been utilized in a regional context thus the paper contributes to the empirical literature by analysing the extent to which individual heterogeneity and intra regional variation in labour market opportunities impact upon the observed distribution of unemployment duration s in particular the paper analyses the extent to which the duration of unemployment is determined by individual choice this is an important issue for the formation and evaluation of policy these result

the market for academic journals library journal subscriptions are treated as a public good a monopoly publisher sells subscriptions to both libraries and individuals for individuals the journal is a private good profit maximization can lead to high institutional prices and few individual subscribers this outcome is reinforced by increases in publishing costs library serial prices fall if patrons pay access costs and or there is congestion data are presented to support these conclusions library prices are two to ten times higher than private prices there are as few as two to four individual subscribers in an academic journal market library subscription prices are directly related to the number of consumers who use the library serial

can helping the sick hurt the able incentives information and disruption in a welfare reform the uk jobcentre plus reform sharpened bureaucratic incentives to help disability benefit recipients relative to unemployment insurance recipients into jobs in the long run the policy raised exits off diasability benefits by 10 and left unemployment outflows roughly unchanged consistent with i beneficial effects of reorganising welfare offices for both groups and ii a shift in bureaucrats efforts towards getting disability benefit recipients into jobs relative to those on unemployment benefit the policy accounted for about 30 of the decline in the aggregate disability rolls between 2003 and 2008 in the short run however we detect a reduction in unemployment exits and no effect on disability exits suggesting important initial disruption effects from the big reorganisation this highlights the difficulty of welfare reform as policymakers may focus on the short run political costs rather than the long run economic benefits

pricing of scientific journals and market power we analyze the empirical relationship between journal prices their quality measured by their citation counts their age as well as conduct of publishers the database covers 22 scientific fields and over 2600 among the most highly reputed and cited journals in 2003 we show that a for profit journals charge roughly 3 times more than journals run by scientific societies b the number of citations has a positive impact on prices c there are large differences in prices across fields that vary from 1 and 6 these are highly and positively correlated with the degree of concentration in the industry

structural empirical evaluation of job search monitoring to evaluate search effort monitoring of unemployed workers it is important to take account of post unemployment wages and job to job mobility we structurally estimate a model with search channels using a controlled trial in which monitoring is randomized the data include registers and survey data on search behavior we find that the opportunity to move to better paid jobs in employment reduces the extent to which monitoring induces substitution toward formal search channels in unemployment job mobility compensates for adverse long run effects of monitoring on wages we examine counterfactual policies against moral hazard like reemployment bonuses and changes of the benefits path

improving incentives in unemployment insurance a review of recent research abstract this paper provides a review of the recent literature on how incentives in unemployment insurance can be improved we are particularly concerned with three instruments i e the duration of benefit payments or more generally the time sequencing of benefits monitoring in conjunction with sanctions and workfare our reading of the theoretical literature is that the case for imposing a penalty on less active job search is fairly solid a growing number of empirical studies including randomized experiments are in line with this conclusion
