transition and capital misallocation the chinese case this paper demonstrates that the allocation of household savings to state owned enterprises soes in china and not to the increasing share of private firms explains both the patterns of capital flows fdi entries and the accumulation of foreign assets and the drop in the consumption share during china s transition the contribution is to explain these two elements in a dynamic general equilibrium model with tfp growth that differentiates fdi and foreign assets in addition to other frictions financial intermediation and soes have the crucial role by misdirecting household savings it modifies firms labor and capital intensiveness and creates shifts in savings accumulation and capital flows moreover the increasing share of credit constrained private firms hinders wage growth and returns on household savings are low to finance soes these two elements reduce the consumption share with a calibration adapted to the chinese economy and deterministic shocks the model also matches to a large extent the data for a variety of stylized facts over the last 30 years

china s macroeconomic imbalances causes and consequences in recent years china has experienced two forms of extreme macroeconomic imbalance an expenditure imbalance in the sense of very high investment and very low consumption giving rise to rapid capital accumulation and an imbalance between expenditure and production producing external imbalance i e a huge surplus on the current account of the balance of payments both imbalances imply a low rate of time discount by both government and society consumption in the present is forgone in favour of consumption in the future the paper examines how these imbalances came about and goes on to consider whether they can be sustained and how they might be redressed there is no evidence that the rapid capital accumulation has reduced the rate of profit on capital and thus the incentive to invest however persistent external imbalance poses a threat to investment if it generates excess liquidity and asset bubbles the current account surplus rose remarkably in the years 2004 07 this was associated with exogenous increases in competiveness and in saving both attributable to the economic reform policies on current policies the surplus is likely to rise again once the world economy recovers from its recession this poses three sorts of problems each of which is examined in turn difficulties for macroeconomic stabilisation policies risk of capital loss on the foreign exchange holdings and the threat of retaliation by china s trading partners a combination of internal and external policies will be required to redress the imbalance

institutional determinants of labor reallocation in transition the transition process differed in the countries of the former soviet union fsu and those of central and eastern europe cee in terms of reallocation of labor real wage employment and output adjustment we sift through the theoretical and empirical literature to find an explanation for these diverging adjustment trajectories and conclude that they can be explained by the fact that the cee countries adopted social policies that upheld wages at the bottom of the distribution forcing the old sector to restructure or collapse while the fsu countries allowed wages to free fall not forcing the hand of the old sector

faulting internationally coordinated fiscal stimulus fiscal policy has been actively deployed globally by g20 governments to counter the impact of the global financial crisis on the real sectors of their economies this coordinated fiscal response has involved a mix of new public expenditure including on infrastructure tax relief and increased income transfers to favoured groups in the end the case for fiscal stimulus rests on the presumption that it works in theory along lines first proposed by keynes yet keynesian fiscal activism founded on this presumption is contestable on numerous theoretical and practical grounds this paper addresses key concerns about the consequences of using fiscal stimulus it proposes that discretionary fiscal measures that have increased budget deficits and public indebtedness for economies worldwide entail significant macroeconomic costs and risks and that as a corollary reducing unproductive public spending can be expansionary

do stronger intellectual property rights increase innovation summary do stronger intellectual property rights ipr increase innovation recent decades have seen a global transformation in ipr standards underpinned by the theory that stronger iprs spur increased incentives to innovate this study tests the impact of ever more rigorous ipr systems on innovation through an index of economic complexity of 94 countries from 1965 to 2005 our results confirm that stronger intellectual property systems engender higher levels of economic complexity nevertheless only countries with an initial above average level of development and complexity enjoy this effect

the economic integration of post wall germany it would be hard to devise a better controlled experiment for comparing different economic systems than the experience provided by east germany and west germany two nations that formerly were one occupied by people of the same background the same culture and the same genetic inheritance torn apart by the accident of war on one side of the berlin wall is a relatively free economic system on the other side a collectivist society milton friedman in w breit and r w spencer 1986 p 89

china as a reserve sink the evidence from offset and sterilization coefficients china has been stockpiling international reserves at an extremely rapid pace since the late 1990s and has surpassed japan to become the largest reserve holder in the world this paper undertakes an empirical investigation to assess the extent of de facto sterilization and capital mobility using monthly data between mid 2000 and late 2008 we find that china has been able to successfully sterilize a large portion of these reserve increases thus making it a reserve sink such as germany was under the bretton wood system

the price of innovation new estimates of drug development costs the research and development costs of 68 randomly selected new drugs were obtained from a survey of 10 pharmaceutical firms these data were used to estimate the average pre tax cost of new drug development the costs of compounds abandoned during testing were linked to the costs of compounds that obtained marketing approval the estimated average out of pocket cost per new drug is us 403 million 2000 dollars capitalizing out of pocket costs to the point of marketing approval at a real discount rate of 11 yields a total pre approval cost estimate of us 802 million 2000 dollars when compared to the results of an earlier study with a similar methodology total capitalized costs were shown to have increased at an annual rate of 7 4 above general price inflation 2003 elsevier science b v all rights reserved

can socioeconomic heritage produce a lost generation with regard to entrepreneurship a considerable amount of literature deals with the influence of institutions on entrepreneurship but for all that little is known about the interplay between institutions and personal determinants of entrepreneurship in this paper the empirical evidence that older people in transition economies have low engagement in entrepreneurial activity is the starting point for analyzing how institutions moderate the relationship between individual characteristics and entrepreneurial choice the results show that the socioeconomic heritage of being exposed to socialism deters entrepreneurship an effect that is more pronounced for high impact entrepreneurship detailed analyses reveal that the effect is driven by devaluation of socialist work experience and the influence of socialism on mindset

the u s patent system in transition policy innovation and the innovation process abstract this paper surveys the major changes in patent policy and practice that have occured in the last two decades in the u s and reviews the existing analyses by the economists that attempt to measure the impacts these changes have had on the processes of technological change it also reviews the broader theoretical and empirical literature that bears on the expected effects of changes in patent policy despite the significance of the policy changes and the wide availability of detailed data relating to patenting robust conclusions regarding the empirical consequences for technological innovation of changes in patent policy are few possible reasons for these limited results are discussed and possible avenues for future research are suggested

determinants of patent rights a cross national study abstract this paper presents an index of patent rights for 110 countries for the period 1960 1990 the index is used to examine what factors or characteristics of economies determine how strongly patent rights will be protected the evidence does indicate that more developed economies tend to provide stronger protection but the underlying factors which influence patent protection levels are the country s level of research and development r d activity market environment and international integration which are correlated with its level of development the results qualify however that r d activity influences patent protection levels after a nation s research sector reaches a critical size an implication of this is that to raise patent protection levels in weakly protecting countries it is important to foster a significant research base in those countries and thereby create incentives for protecting patent rights

the effect of intellectual property rights on domestic innovation in the pharmaceutical sector summary there is little empirical evidence concerning the effect of intellectual property rights ipr protecting pharmaceutical products and processes on pharmaceutical domestic innovation indeed existing literature does not provide a punctual estimate of this effect for developing countries this paper fills this gap by exploiting a self constructed dataset which provides for a 22 year period information concerning ipr reforms involving pharmaceuticals for 74 developed and developing countries the identification strategy exploits the different timing across these countries of two sets of ipr reforms domestic innovation is measured as citation weighted domestic patent applications filed at the european patent office epo the highly skewed distribution of the dependent variable and the high number of zero observations are taken into account using count data models in particular a zero inflated negative binomial model is adopted to overcome previous literature assumption that all innovations are patented in the main markets of reference and to take into consideration the choice not to patent at the epo results show that innovation is sensitive to ipr protection but not to its degree moreover the effect is not long lasting my study also finds that developing countries profit significantly less than developed ones from the protection benefiting from an effect that is roughly half of that for developed countries consequent policy implications are examined and include the conclusions that a one size fits all approach can be inappropriate and that gradual reforms should be preferred to rare reforms that greatly alter the level of ipr protection

innovation and market structure in the dynamics of the pharmaceutical industry and biotechnology towards a history friendly model this paper is a first attempt at modelling the long term dynamics of market structure and innovation in the pharmaceutical industry in a history friendly way the model examines the relationships between the nature of the search space demand the patterns of competition and industry evolution in the age of random screening and in the age of molecular biology and shows that concentration in the pharmaceutical industry is shaped by lack of cumulativeness in innovative activities and market fragmentation the model conforms to our appreciative understanding and responds to changes in parameters concerning demand costs economies of scale opportunity conditions and the relative advantages of new biotechnology firms nbfs vis a vis incumbents with the exception of cost increases the model is quite robust to these changes in its essential features it is quite difficult to raise substantially concentration and to have nbfs displacing incumbents

the effect of joint custody on family outcomes since the 1970s almost all us states have introduced a form of joint custody after divorce i analyze the causal effect of these custody law reforms on different family outcomes my identification strategy exploits the different timing of reforms across the us states estimations based on state panel data suggest that the introduction of joint custody led to an increase in marriage rates an increase in overall fertility including a shift from nonmarital to marital fertility and an increase in divorce rates for older couples accordingly female labor market participation decreased further male suicide rates and domestic violence fell in treated states the empirical evidence is consistent with the hypothesis that joint custody increased the relative bargaining power of men within marriage

patents and the global diffusion of new drugs analysis of the timing of launches of 642 new drugs in 76 countries during 1983 2002 shows that patent and price regulation regimes strongly affect how quickly new drugs become commercially available in different countries price regulation delays launch while longer and more extensive patent rights accelerate it health policy institutions and economic and demographic factors that make markets more profitable also speed up diffusion the estimated effects are generally robust to controlling for endogeneity of policy regimes with country fixed effects and instrumental variables the results highlight the important role of policy choices in driving the diffusion of new innovations

winners and losers in transition returns to education experience and gender in slovenia the authors identify winners and losers in slovenia s economic transition by tracing changes in returns to education experience and gender and changes in wage inequality from 1987 to 1991 they find the following relative wages and employment rose for the most educated and fell for the least educated in all industries relative wages and employment rose with years of work experience until pensionable age at pensionable age relative wages increased very rapidly and relative employment was greatly reduced using pension policies to encourage early retirement drastically reduced the supply of very experienced workers either the policy caused firms to bid up wages for workers of pensionable age to keep them from retiring or it caused a selection process in which only the highest paid workers remained in the workforce regardless the pension policy has proved to be costly and early retirements did not make room for the youngest workers but for those just under pensionable age women gained relative to men in both wages and employment primarily because they occupy education and industry groups less adversely affected by the transition not because of economywide reductions in discrimination against women increasing returns to education and experience contributed to wage inequality but the variance in wages also increased for individuals with identical skills big changes in relative wages should signal future reallocation of labor toward more productive higher paying sectors setting minimum wages fixing ranges of pay and indexing wages to inflation did not prevent increases in wage variation from occuring wage minimums did not appear to have an effect presumably because inflation reduced real minimum wages so quickly that most workers were paid above the minimums in slovenia policy changes are reflected in labor market outcomes disabling the tax transfer policy from relatively profitable to relatively unprofitable firms and eliminating worker referendums on wage scales removed mechanisms that tended to compress wage variation greater demand for skilled workers also reflected both the economywide need to cope with uncertainty and such industry specific factors as reduced labor demand especially in less skill intensive industries the results in slovenia contrast sharply with those in eastern germany eastern german workers have had decreasing returns to education and experience but it is not clear how relevant the eastern german experience is to other transitional economies because of western germany s efforts to alleviate problems more similar to the authors findings are the results of flanagan 1993 on the czech republic which show increasing returns to education but decreasing returns to experience in some respects slovenia is atypical because it is richer and more western in orientation than other transitional economies however economies could learn from the experience in slovenia because slovenia also had social ownership full employment coupled with substantial hidden unemployment and an egalitarian wage structure and slovenia has introduced labor market reform and experienced social dislocations similar to those in other transitional european economies

do national patent laws stimulate domestic innovation in a global patenting environment a cross country analysis of pharmaceutical patent protection 1978 2002 this paper evaluates the effects of patent protection on phar maceutical innovations for 26 countries that established pharmaceutical patent laws during 1978 2002 controlling for country characteristics through matched sampling techniques to establish two proper comparison sets among 92 sampled countries and through country pair fixed effects regressions this study yields robust results national patent protection alone does not stimulate domestic innovation as estimated by changes in citation weighted u s patent awards domestic r d and pharmaceutical industry exports however domestic innovation accelerates in countries with higher levels of economic development educational attainment and economic freedom additionally there appears to be an optimal level of intellectual property rights regulation above which further enhancement reduces innovative activities

how do patent laws influence innovation evidence from nineteenth century world fairs studies of innovation have focused on the effects of patent laws on the number of innovations but have ignored effects on the direction of technological change this paper introduces a new dataset of close to fifteen thousand innovations at the crystal palace world s fair in 1851 and at the centennial exhibition in 1876 to examine the effects of patent laws on the direction of innovation the paper tests the following argument if innovative activity is motivated by expected profits and if the effectiveness of patent protection varies across industries then innovation in countries without patent laws should focus on industries where alternative mechanisms to protect intellectual property are effective analyses of exhibition data for 12 countries in 1851 and 10 countries in 1876 indicate that inventors in countries without patent laws focused on a small set of industries where patents were less important while innovation in countries with patent laws appears to be much more diversified these findings suggest that patents help to determine the direction of technical change and that the adoption of patent laws in countries without such laws may alter existing patterns of comparative advantage across countries jel d2 k11 l51 no 014

patents and cumulative innovation causal evidence from the courts cumulative innovation is central to economic growth do patent rights facilitate or impede such follow on innovation this paper studies the effect of removing patent protection through court invalidation on the subsequent research related to the focal patent as measured by later citations we exploit random allocation of judges at the u s court of appeal for the federal circuit to control for the endogeneity of patent invalidation we find that patent invalidation leads to a 50 percent increase in subsequent citations to the focal patent on average but the impact is highly heterogeneous patent rights appear to block follow on innovation only in the technology fields of computers electronics and medical instruments moreover the effect is entirely driven by invalidation of patents owned by large patentees that triggers entry of small innovators suggesting that patents may impede the democratization of innovation

value of human capital in transition to market evidence from slovenia abstract the paper summarizes existing hard evidence concerning the changing value of human capital in slovenia s transition to a market system it investigates changes in patterns of job mobility via estimating multinomial logit and hazard models and changes in the structure of wages via earnings functions associated with education experience gender and ethnicity data are drawn from unusually rich administrative data sets that include personal characteristics work history and earnings for virtually all labor force participants all evidence points to rapidly increasing marginal returns to human capital in transition economies

japan s shift from process to product patents in the pharmaceutical industry an event study of the impact on japanese firms in 1975 japan expanded the scope of its patent law by introducing product patents for newly developed chemical and pharmaceutical products we use rate of return data from the tokyo stock exchange for japanese pharmaceutical companies to examine the impact of the change in the patent law our empirical findings indicate that the passage of the new patent law induced an excess return of approximately 26 percent to a portfolio of large pharmaceutical companies companies with r d programs specializing in new product development experienced large gains while companies with r d programs specializing in imitative process patents experienced no gains

what percentage of innovations are patented empirical estimates for european firms abstract a 1993 survey on the innovative activities of europe s largest industrial firms obtained useable results on patenting activities for 604 respondents the data are used to calculate the sales weighted propensity rates for 19 industries the propensity rates equal the percentage of innovations for which a patent application is made the propensity rates for product innovations average 35 9 varying between 8 1 in textiles and 79 2 in pharmaceuticals the average for process innovations is 24 8 varying from 8 1 in textiles to 46 8 for precision instruments only four sectors have patent propensity rates for both product and process innovations combined that exceed 50 pharmaceuticals chemicals machinery and precision instruments regression results that control for the effect of industry sector show that patent propensity rates increase with firm size and are higher among firms that find patents to be an important method for preventing competitors from copying both product and process innovations the effect of secrecy is not so straightforward firms that find secrecy to be an important protection method for product innovations are less likely to patent as expected but secrecy has little effect on the propensity to patent process innovations the r d intensity of the firm has no effect on patent propensity rates for both product and process innovations the sector of activity has a strong influence on product patent propensities but very little effect on process patent propensities after controlling for the effect of other factors

china s exchange rate trap japan redux today s american mercantile pressure on china to appreciate the renminbi against the dollar is eerily similar to the american pressure on japan to appreciate the yen that began over 30 years ago indeed the yen went all the way from 360 to the dollar in august 1971 at the end of the bretton woods period of fixed exchange rate parities to touch 80 to the dollar in april 1995 then the american government relented and announced a strong dollar policy that signaled the end of japan bashing but the overvalued yen and the expectation of appreciation destabilized the japanese financial system the bubble economy of the late 1980s was followed by a deflationary slump and a zero interest liquidity trap in the 1990s mckinnon and ohno 1997 at least some of today s critics of east asian countries pegging to the dollar would agree that international saving imbalances rather than misaligned exchange rates are the root cause of the u s current account deficit one can argue whether it is mainly a saving deficiency in the united states or a saving glut in the rest of the world bernanke 2005 either way the central position of the united states under the world dollar standard gives it alone an unlimited international line of credit in its own currency however suppose that the u s trade deficit is misdiagnosed to result from a misaligned exchange rate so that a surplus country on the dollar s periphery is forced to appreciate against the world s dominant money it will suffer a slowdown in economic

what is behind the recent surge in patenting abstract we investigate the cause of an unprecedented surge of us patenting over the past decade conventional wisdom points to the establishment of the court of appeals of the federal circuit by congress in 1982 we examine whether this institutional change which has benefited patent holders explains the burst in us patenting using both international and domestic data on patent applications and awards we conclude that the evidence is not favorable to the conventional view instead it appears that the jump in patenting reflects an increase in us innovation spurred by changes in the management of research

can africa compete with china in manufacturing the role of relative unit labor costs in this paper examine sub saharan africa s ssa bilateral trade and cost competitiveness with china we review patterns of bilateral trade between ssa and china showing an extraordinary imbalance in the structure of trade in that china overwhelmingly exports manufactured products to ssa and almost exclusively imports primary products in return our principal means of assessing the competitiveness of ssa s manufacturing sector vis a vis china are measures of relative unit labor costs rulc we find that african rulc levels have generally been very high relative to china but declined over the 2000s as china s wages have risen faster than chinese productivity while the reverse is true for the ssa countries in our sample nevertheless rulc vis a vis china remained elevated for many ssa countries as of 2010 generally high rulc along with weaknesses in the business climate suggest that most ssa countries are unlikely to be competitive in labor intensive manufacturing any time soon

wage effects of the move toward free markets in east germany this analysis of data from the german socio economic panel soep for the years 1989 91 illuminates important changes in the structure of wages that were occurring in the former east germany during its transition toward a capitalist economy and changes that are probably occurring in other countries in eastern europe as well under the new capitalist wage regime workers realized significant returns to schooling gained under socialism but no significant returns to work experience because work experience is the largest element in the human capital of older workers their wages fell under the new system and the results suggest that their wages will continue to fall relative to those of younger workers generous transfer payments from western germany may prevent an absolute decline in living standards of these workers older workers in other eastern countries however will have no such social assistance and their living standards will probably fall

the mystery of the chinese exchange rate regime basket or no basket economists have taken for granted the claim made by the chinese government that the policy shift introduced in july 2005 constituted a change in the exchange rate regime from a fixed peg to a basket peg we demonstrate that neither the stylized facts nor the empirical evidence support the proposition of a basket peg and suggest several reasons as to why china has not adopted this regime the results could prove useful for identifying the chinese exchange rate regime in the aftermath of the perceived policy shift following the august 2015 devaluation

just how low are china s labour costs this paper provides a new perspective on chinese international competitiveness in manufacturing using relative unit labour costadvantage than that implied by a comparison of wages alone china s cost advantage derives from large currency devaluations thas t preceded the establishment of a de facto peg around 1995 and rapid productivity growth in the period since 1995 we nd that chinese unit labour costs are about 25 40 per cent of us labour costs they are also low relative to costs in the eu japan mexico korea and most other newly industrialising countries however china s relative unit labour costs indicatea substantially smaller cost

post unification wage growth in east germany following monetary union with west germany in 1990 the real wage of east german workers rose 83 i use the german socio economic panel data to investigate the determinants of wage growth and assess whether they are consistent with efficient restructuring although job changing rates were initially high the share of wage growth that accrued to movers was little higher than in the west suggesting that the incentives to move were too low for 1990 to 1991 the biggest gainers were low wage workers generally and women and the less educated specifically for 1991 to 1996 the biggest gainers were women and the better educated

the patent paradox revisited an empirical study of patenting in the u s semiconductor industry 1979 1995 we examine the patenting behavior of firms in an industry characterized by rapid technological change and cumulative innovation recent survey evidence suggests that semiconductor firms do not rely heavily on patents to appropriate returns to r d yet the propensity of semiconductor firms to patent has risen dramatically since the mid1980s we explore this apparent paradox by conducting interviews with industry representatives and analyzing the patenting behavior of 95 u s semiconductor firms during 1979 1995 the results suggest that the 1980s strengthening of u s patent rights spawned patent portfolio races among capital intensive firms but it also facilitated entry by specialized design firms

a penny for your quotes patent citations and the value of innovations the use ofpatents in economic research has been seriously hindered by the fact that patents vary enormously in their importance or value and hence simple patent counts cannot be informative about innovative output the purpose of this article is to put forward patent counts weighted by citations as indicators of the value of innovations thereby overcoming the limitations of simple counts the empirical analysis of a particular innovation computed tomography scanners indeed shows a close association between citation based patent indices and independent measures of the social value of innovations in that field moreover the weighting scheme appears to be nonlinear increasing in the number of citations implying that the informational content of citations rises at the margin as in previous studies simple patent counts are found to be highly correlated with contemporaneous rd however here the association is within afield over time rather than cross sectional

alfred marshall lecture intellectual property rights protection in developing countries the case of pharmaceuticals patent enforcement in developing countries generates considerable controversy especially when patents involve potentially life saving drugs this paper argues that common concerns regarding the effects of patents on prices and on research incentives of pharmaceutical multinationals are misplaced rather the most significant effects are likely to concern access to patented drugs in poor countries because prices in developing countries are much lower than in the developed world multinationals may choose to enter such markets with a delay or not at all implying a complete loss of access to patented drugs in developing countries even when multinationals enter countries like india their marketing and distribution networks are not currently built out leading to limited access within the country such considerations may provide a justification for policies targeting access in the short and medium run such as compulsory licensing

how broad should the scope of patent protection be i explore the trade off between a patent s length that is its lifetime and its width that is its scope of coverage a wider patent generally reduces the distortion of consumers choices between the patented brand of the product and unpatented lower priced varieties sold by competitors but also permits higher prices which increase relative to profits the deadweight losses from consumers switching consumption out of the product class i show under what conditions infinitely lived but very narrowly focused patents are the socially efficient way to reward innovation and under what conditions very short lived but very broad patents are optimal

why is china so competitive measuring and explaining china s competitiveness this paper evaluates factors responsible for the competitiveness of china in the world economy and relative to its east asian rivals china has been highly successful in capturing world export markets chinese competitiveness is not just a matter of an undervalued exchange and extremely low labor costs it reflects primarily the coincidence of favorable cost conditions with improvements in china s ability to produce products that meet world market specifications these improvements are closely related to foreign participation in china s economy through foreign direct investment and joint venture enterprises

the transition in east germany when is a ten point fall in the gender wage gap bad news the gender wage gap in east germany has narrowed by 10 percentage points in transition but women have experienced much more severe employment difficulties than men using the german socio economic panel for 1990 94 i show that on balance women have lost relative to men almost half the relative wage gain is due to exits from employment of the low skilled who are disproportionately women the female employment decline is not primarily voluntary more than half the gender gap in the hazard rate from employment reflects a general fall in demand for low skilled workers reduced child care plays no role

returns to human capital under the communist wage grid and during the transition to a market economy we estimate returns to human capital during communism and the transition using data on 2 284 men in the czech republic we show a extremely low and constant rates of return to education under the communist wage grid and dramatic increases in transition which do not differ by firm ownership b radical changes in returns to several fields of study and sheepskin effects in both regimes c identical wage experience profile in both regimes d similar 1996 returns to human capital obtained in communism and in transition and e changes in the interindustry wage structure a decomposition of the variance of wages finds individuals unobservable effects from communism to persist into transition but most of the variance is due to unobservable effects introduced in the transition

south africa s international cost competitiveness and exports in manufacturing abstract the new south african government has embraced globalization with mixed results to date controversies center on south africa s international cost competitiveness and whether south african exports respond to changes in competitiveness we measure competitiveness by relative unit labor costs we find that south african relative unit labor costs declined in the 1990s but are still high relative to other developing countries econometric analysis reveals a strong effect of relative unit labor costs on exports
