does tourism influence economic growth a dynamic panel data approach on average tourism specialized countries grow more than others this is not consistent with the core of modern economic growth theory that suggests that economic growth is linked to sectors with high tech intensity and large scale in this article we use appropriate panel data methods to study the relationship between tourism and economic growth in general we show that tourism is a positive determinant of economic growth both in a broad sample of countries and in a sample of poor countries however contrary to previous contributions tourism is not more relevant in small countries than in a general sample this is a fully modified version of a working paper co authored by one of the authors

deposit insurance and external finance i introduction capital markets serve an essential purpose in the growth and development of modern economies they provide for the efficient channeling of funds from savers to investors there are two basic methods for financing capital investment primary issuance of equity or bonds and securing of bank loans looking around the world we see that countries differ substantially in the relative importance of banks and capital markets in providing investment financing equity market capitalization currently ranges from close to zero in countries like austria argentina and greece to nearly two times gross domestic product gdp in the united kingdom south africa and malaysia the importance of bank loan financing is essentially the mirror image of this what accounts for the cross country differences in the importance of banks and capital market financing of investment the purpose of this article is to address this question directly we contend that much of the variation across countries in the depth and breadth of capital markets can be explained by a combination of the existence of deposit insurance and the extent to which a country s banking system is state owned because of the importance of financial intermediation and the difficulties associated with potential bank failures governments in most countries have established a set of institutional structures to ensure the stability of their banking systems primary among these is the creation of deposit insurance by insuring deposits banks liability holders are significantly less likely to request the return of callable deposits reducing the chances of bank runs but at the same time deposit insurance subsidizes bank risk taking activities and allows the payment of lower interest rates to depositors 1 this channels money through banks and away from financial markets direct state bank ownership has a similar impact see barth et al 2001 la porta et al 2000 we present a simple three sector model in which the economy is composed of firms banks and households the firms require operating capital and can obtain it either through equity issuance or from bank loans banks take deposits from households and make loans to firms while households both allocate their wealth and purchase the firms output the model allows us to show how increases in deposit insurance or the percentage of the banking system that is state owned both reduces the size of the capital market and shrinks the amount of bank credit to the private sector and may decrease the number of firms seeking equity financing to examine the predictions of the model we study a data set composed of 49 countries of these 33 currently have explicit deposit insurance and 42 have some state ownership of banks ranging from less than 2 to almost 90 the data confirm the predictions of the model an increase in either state bank ownership or presence of deposit insurance both decreases the size of capital markets and the extent of bank lending for example we would predict that decreasing the percentage of the banking system that is state owned from 36 as it is in italy to zero would increase in the size of the capital market from less than 10 to over 30 of gdp and a raise in the level of bank lending from 57 to close to 90 of gdp our conclusions are in contrast with those in la porta et al 1997 who study the relationship between law and finance la porta et al note the importance of the countries legal system in determining the structure of the financial system in particular they point out that investors provide capital to firms only if they believe they will get their money back for equity holders this means that they must be able to vote out directors and managers who do not pay them for creditors and holders of bonds this means that they must have authority to repossess collateral furthermore these nominal legal rights must be accompanied by confidence that the laws will be enforced

do better schools matter parental valuation of elementary education the evaluation of numerous school reforms requires an understanding of the value of better schools given the difficulty of calculating the relationship between school quality and student outcomes i turn to another method and use house prices to infer the value parents place on school quality i look within school districts at houses located on attendance district boundaries houses then differ only by the elementary school the child attends i thereby effectively remove the variation in neighborhoods taxes and school spending i find that parents are willing to pay 2 5 percent more for a 5 percent increase in test scores this finding is robust to a number of sensitivity checks

using maimonides rule to estimate the effect of class size on scholastic achievement the twelfth century rabbinic scholar maimonides proposed a maximum class size of 40 this same maximum induces a nonlinear and nonmonotonic relationship between grade enrollment and class size in israeli public schools today maimonides rule of 40 is used here to construct instrumental variables estimates of effects of class size on test scores the resulting identiecation strategy can be viewed as an application of donald campbell s regression discontinuity design to the class size question the estimates show that reducing class size induces a signiecant and substantial increase in test scores for fourth and efth graders although not for third graders when asked about their views on class size in surveys parents and teachers generally report that they prefer smaller classes this may be because those involved with teaching believe that smaller classes promote student learning or simply because smaller classes offer a more pleasant environment for the pupils and teachers who are in them mueller chase and walden 1988 social scientists and school administrators also have a longstanding interest in the class size question class size is often thought to be easier to manipulate than other school inputs and it is a variable at the heart of policy debates on school quality and the allocation of school resources in many countries see e g robinson 1990 for the united states ofsted 1995 for the united kingdom and moshel ravid 1995 for israel this broad interest in the consequences of changing class size

monetary policy and transaction costs empirical analysis of consumption function for the united states of america 1988 2014 abstract in macroeconomic theory different approaches discuss the ability of monetary policy to affect real variables in the long run this research proposes the empirical application of a theoretical model that includes nominal rigidities arising from transaction costs and real rigidities arising from the firms competition structure thus based on data from the us economy we propose to test the theoretical results combining the existence of shocks arising from both real factors and factors affecting the money market establishing tests for shocks of supply and aggregate demand the concern is to investigate if the economic policy is capable of affecting the long run average values of the real private consumption time series analysis methodology of structural vector autoregressive svar models was used to test long run relationship for us economy the ability to establish the long run relationships between these aggregates with some degree of confidence allow simulating shocks by impulse response functions and variance decomposition the theoretical results of the model indicate that productivity transaction costs number of transactions with credit debit cards and currency money tend to positively influence consumption whereas delinquency have a negative effect on consumption we tested two empirical specifications and both confirmed the theoretical results for the us economy and therefore the research can help policymakers to measure the long run consequences of their decisions that is the results converge on the non neutrality of money in the long run in the us economy

the determinants of italian domestic tourism a panel data analysis abstract in this study a gmm panel data estimation is used to investigate the main determinants of italian domestic tourism demand as measured by regional bilateral tourism flows the analysis is developed both at aggregate level and for the two traditional macro areas of the country namely centre north and south for the whole nation the importance of traditional economic variables in determining domestic tourism flows is confirmed however tourist actual choices appear also to be influenced by past experiences and by regional differences in the quality of the wider environment additionally it appears that for italian tourists domestic and international destinations behave as substitutable goods the sub sample analysis highlights some interesting differences between macro areas in particular southern tourists appear more responsive to income variations and less sensitive to prices differentials than their northern counterparts moreover the degree of competition between domestic and outbound trips is higher in the south finally southern tourists seem to be more influenced by environmental attributes while northern tourists are more sensitive to cultural activities

determinants of international tourism a three dimensional panel data analysis international tourism is a fast growing industry generating half a trillion dollars in annual revenues and accounting for almost 10 of total international trade and almost half of total trade in services yet it has so far failed to receive the attention it deserves from mainstream economics this paper attempts to provide an initial understanding of the determinants of international tourism this paper claims that international tourism as other forms of trade in services is driven by unique factors of production and may be better dealt with in a single industry study rather than in a general equilibrium trade model in order to understand these determinants the world is viewed as a market of differentiated products and a discrete choice estimation technique is applied to a large three dimensional data set of tourist flows it is shown that a relatively simple estimation technique combined with a rich data set can deliver reasonable substitution patterns it is found among other things that pol

the impact of national research funds a regression discontinuity approach to the chilean fondecyt this paper analyzes the role of national research funds in promoting scientific production in emerging economies the study focuses on the impact of the chilean national science and technology research fund fondecyt the analysis uses data drawn from international sources of bibliometric information combined with the administrative records of the program s executing unit to measure the program s impact we implement a regression discontinuity rd design on principal researchers who applied for funding between 1988 and 1997 considering as outcomes both quantity publications up to 2002 and quality citations up to 2005 of their scientific production our results show significant and positive impact in terms of publications but no impact in terms of quality of scientific production in the proximity of the program s threshold ranking

tall paper walls the political economy of visas and cross border travel cross border travel for business personal and tourism purposes is an important component of trade in services in 2013 travel accounted for 25 of services export in the world trade in services accounted for 12 of gdp in the world hence the role of travel in many economies is substantial the current paper studies the determinants of cross border flows of people with a particular emphasis on the role of visa policies we adopt the un general assembly affinity index a measure of the quality of bilateral relations between nations to instrument for bilateral visa policy we find that ceteris paribus imposing visa restrictions on a country reduces travel from that country by about 73 in 2010 implying restrictive visa policies discourage cross border travel significantly this implies an adverse impact of restrictive visa policies on trade in services

public policies to support basic research what can the rest of the world learn from us theory and practice and what they should not learn the information based theoretical model for public support of basic research developed in the usa at the end of the 1950s has held up well in practice in spite of its neglect of training benefits of necessary investment in research infrastructure and of its consequently limited relevance outside the usa at the same time us practice in basic research has often been misinterpreted as being driven by short term usefulness whereas its key features are massive and pluralistic government funding high academic quality and the ability to invest in the long term development of new often multi disciplinary fields challenges for the future include greater and often ill judged pressures from governments for demonstrable usefulness of the basic research it supports the entirely separate development of direct links to application in bio medical and software fields and more complicated links between basic research and application resulting from the changes in the internationalisation of corporate r d effective policies will depend on better understanding of what makes universities responsive to investments in promising new fields of research and teaching how and why basic fields of great practical usefulness emerge and how basic research requirements are conditioned by a country s level and pattern of economic development bibliometric data could make a considerable contribution if it was more widely recognised that they have informational properties similar to the output of basic research and therefore deserve public support this paper was prepared for the celebration of richard nelson s 70th birthday held in nyc from 13 15 october 2000 comments welcome

does anticipated aggregate demand policy matter further econometric results a heated debate has arisen over what modigliani has dubbed the macro rational expections mre hypothesis this hypothesis embodies two component hypotheses 1 rational expectations and 2 short run neutrality i e that anticipated changes in aggregate demand will have already been taken into account in economic agents behavior and will thus evoke no output or employment response together these component hypotheses imply that deterministic feedback policy rules will have no effect on business cycle fluctuations the irrelevance of these types of policy rules is inconsistent with much previous macro theorizing as well as with the views of policymakers it is thus an extremely controversial proposition which requires a wide range of empirical research this paper is a sequel to a previous paper by the author that paper developed a methodology for testing the mre hypothesis and found that anticipated money growth does matter to the business cycle this paper extends the analyses to cases where the rate of nominal gnp growth or the inflation rate rather than money growth is the aggregate demand variable the empirical results are also negative on the mre hypothesis and its corresponding policy ineffectiveness proposition this abstract was borrowed from another version of this item

stabilising properties of discretionary monetary policies in a small open economy this article sets out a simple new keynesian open economy model and shows that the conduct of discretionary monetary policy in an open economy differs substantially from the closedeconomy framework the article shows analytically that the existence of the direct exchange rate channel in the open economy phillips curve impairs the perfect stabilising property of monetary policy in the face of demand side disturbances under domestic inflation targeting if cpi inflation is instead the target then the perfect stabilising property of monetary policy breaks down even in the absence of the direct exchange rate channel in the phillips curve

in defense of the nsf economics program abstract the nsf economics program funds basic research in economics across all its disparate fields its budget has experienced a long period of stagnation and decline with its real value in 2013 below that in 1980 and having declined by 50 percent as a percent of the total nsf budget the number of grants made by the program has also declined over time and its current budget is very small compared to that of many other funders of economic research over the years nsf supported research has supported many of the major intellectual developments in the discipline that have made important contributions to the study of public policy the public goods argument for government support of basic economic research is strong neither private firms foundations nor private donors are likely to engage in the comprehensive support of all forms of economic research if nsf were not to exist select universities with large endowments are more likely to have the ability to support general economic research in the abse

analysis of optimal timing of tourism demand recovery policies from natural disaster using the contingent behavior method this paper examines the applicability of contingent behavior hereafter cb method for analyzing dynamic processes and efficient policies in tourism demand recovery the cb questionnaires used for this study used a hypothetical disaster situation of bird flu in kyoto japan safety event visitor information and price discounting policies were designed accordingly respondents were then asked about their willingness to travel time the results showed the optimal timing for devising pertinent policies during the year we found that the first step requires a safety information announcement within one week immediately after disaster site decontamination the second step is the implementation of event information policy within 24th to 36th week after the disaster the third step constitutes announcing visitor information within the 37th to 52nd week after the second step the final step is the implementation of price discounting policy until the 52nd week immediately after the third step

the dynamic effects of aggregate demand and supply disturbances we interpret fluctuations in gnp and unemployment as due to two types of disturbances disturbances that have a permanent effect on output and disturbances that do not we interpret the first as supply disturbances the second as demand disturbances demand disturbances have a hump shaped mirror image effect on output and unemployment the effect of supply disturbances on output increases steadily over time peaking after two years and reaching a plateau after five years

is public r d a complement or substitute for private r d a review of the econometric evidence is public r d spending complementary and thus additional to private r d spending or does it substitute for and tend to crowd out private r d conflicting answers are given to this question we survey the body of available econometric evidence accumulated over the past 35 years a framework for analysis of the problem is developed to help organize and summarize the findings of econometric studies based on time series and cross section data from various levels of aggregation laboratory firm industry country the findings overall are ambivalent and the existing literature as a whole is subject to the criticism that the nature of the experiment s that the investigators envisage is not adequately specified we conclude by offering suggestions for improving future empirical research on this issue

sticky prices as coordination failure this paper links the coordination failure and menu cost approaches to the microeconomic foundations of keynesian macroeconomics if a firm s desired price is increasing in others prices then the gain from price adjustment after a nominal shock is greater if others adjust this strategic complementarity leads to multiple equilibria in the degree of rigidity welfare may be much higher in the equilibria with less rigidity thus nominal rigidity arises from a failure to coordinate price changes jel e12 e30 keynesian macroeconomics waned in the 1970 s because economists grew disenchanted with its weak microeconomic foundations the central difficulty was that keynesian models were based on ad hoc rigidities in nominal wages and prices the 1980 s produced two approaches to reviving keynesian theory the menu cost literature n gregory mankiw 1985 george akerlof and janet yellen 1985 seeks to provide rigorous explanations for nominal rigidities these papers argue that small frictions in price setting are enough to produce large nominal rigidities in contrast the coordination failure literature russell cooper and andrew john 1988 abandons nominal rigidities and seeks alternative foundations for keynesian models the central idea is that many economic activities such as production e g john bryant 1983 trade e g peter diamond 1982 and investment e g nobuhiro kiyotaki 1988 exhibit synergism or strategic complementarity one agent s optimal level of activity depends positively on others activity strategic complementarity can lead to multiple equilibria with high activity equilibria superior to low activity equilibria thus an economy may be stuck in an underemployment equilibrium even though a superior equilibrium exists models with nominal rigidities and models with coordination failures are often presented as competing paradigms 1 this paper shows that this view is incorrect we take a step toward unifying the foundations of keynesian economics by showing that the two sets of ideas are highly complementary nominal rigidity arises from a failure to coordinate price changes this failure has the essential features of coordination failures in previous models flexibility in one firm s price increases the incentives for other firms to make their prices flexible this strategic complementarity leads to multiple equilibria in the degree of nominal rigidity equilibria with less rigidity more active price adjustment are often pareto superior to equilibria with more rigidity these results contribute to our understanding both of coordination failure and of nominal rigidity the range of keynesian phenomena explained by coordination failures is greatly expanded previous coordination failure models contain only real variables and thus ascribe no role to monetary policy or other determinants of nominal spending our results suggest that coordination failure is at the root of inefficient nonneutralities of money theories of nominal rigidities gain new empirical and policy im

research productivity over the life cycle evidence for academic scientists the relationship between age and the publishing productivity of ph d scientists is analyzed using data from the survey of doctorate recipients national research council and the science citation index the longitudinal nature of the data allows for the identification of pure aging effects in five of the six areas studied life cycle aging effects are present only in particle physics where scientists often speak of being on a religious quest is the indication that scientific productivity is not investment motivated vintage effects are also considered the expectation that the latest educated are the most productive is not generally supported by the data copyright 1991 by american economic association

the effectiveness of investment subsidies evidence from a regression discontinuity design this paper analyzes the effects of an investment subsidy program for small and medium sized enterprises in flanders from 2004 to 2009 the subsidies were awarded according to a ranking system that favored young growing and productive firms with a strong cash flow granting subsidies to the highest scoring firms until the depletion of funds the nature of this allocation system creates a sharp cutoff in granting the subsidy according to the score allowing us to estimate the causal impact of the subsidies using a regression discontinuity design we find a positive effect on firm level investment employment output and productivity for the firms that were granted the subsidy but only for the small firms however the effect is small relative to the cost of the subsidy

the impacts of immigrants and institutions on bilateral tourism flows abstract in this paper we use data on recent bilateral tourism flow from 34 organisation for economic co operation and development oecd countries to 52 middle to low income countries for the period 1995 2010 to determine whether immigration trade and institutional quality play a role in driving oecd nationals to visit immigrant source countries except for the african countries the results show that immigrants residing in oecd countries have a positive advertising effect for their home country inducing tourism flows from oecd countries we also find that the quality of institutions along with freedom and civil liberty indices are important in selecting tourism destinations a massive 8 of the variation in tourism flows can be accounted for by these factors these results hold for the subsample and the whole sample with two exceptions european and african destinations we posit that this feature of the data exists because european african countries are so similar to each other and small differences in the indexes do not matter at the top bottom of the distribution by controlling for gravity and macroeconomic stability variables we also show that the trade flows between countries among other factors play a crucial and stable role on tourism flows dynamic panel data estimation is used to account for the influence of repeat visits and support our findings

forecasting long haul tourism demand for hong kong using error correction models forecasting accuracy is particularly important when forecasting tourism demand on account of the perishable nature of the product this study compares a range of forecasting models in the context of predicting annual tourist flows into hong kong from the major long haul markets of the us the uk germany and major short haul markets of china japan and taiwan econometric forecasting models considered included error correction models ecms based on permanent income life cycle pi lc hypothesis pi lc ecm and alternative cointegration approaches engle and granger 1987 johansen 1988 and ordinary least square ols approaches both autoregressive integrated moving average arima and no change model hereafter naive models are used as a benchmark time series model for accuracy comparisons it was hypothesized that pi lc ecm is a better forecasting model particularly for long haul tourism demand the objective of this article is to investigate whether the application of pi lc ecm could improve the

a panel data analysis of the effect of corruption on tourism this study empirically tests the hypothesis that corruption has a negative effect on tourism having to pay bribes while on holiday or a business trip increases the costs of travelling to a country where corruption is prevalent tourists are thus more likely to travel to countries where these additional costs do not need to be incurred this hypothesis is tested using a panel data set of over 100 countries and 16 years the results indicate that a 1 point increase in the corruption perception index implying a decrease in corruption results in a 2 to 7 increase in tourist inflows in addition tourist inflows rise with gdp per capita openness and growth and are higher in countries with a temperate climate

seigniorage and political instability the importance of seigniorage relative to other sources of government revenue differs markedly across countries this paper tries to explain this regularity by studying a political model of tax reform the model implies that countries with a more unstable and polarized political system will have more inefficient tax structures and thus will rely more heavily on seigniorage this prediction of the model is tested on cross sectional data for seventy countries the authors find that after controlling for other variables political instability is positively associated with seigniorage copyright 1992 by american economic association

a quantized approach to rational inattention abstract in this paper i propose a model of rational inattention where the choice variable is a deterministic function of the exogenous variables and still only a finite amount of information is being used this holds provided the choice variable is discrete rather than continuous that is the mapping from the realization of the exogenous variables to the endogenous ones is piece wise constant thus limited information is now a source of lumpiness in behavior rather than a source of noise the approach is applied to a simple static model of price setting where individual price setters face aggregate monetary shocks and idiosyncratic productivity shocks the effect of aggregate money shocks on output and prices is studied it is shown that as the variance of idiosyncratic shocks become large the aggregate log price level converges to a linear function of the aggregate money shock with a coefficient which is strictly between 0 and 1 consequently unanticipated aggregate money shocks have real effects on output in contrast to the sticky price model of caplin and spulber 1987 but these effects are smaller than in standard rational inattention models or in the lucas 1972 misperception model

economic impacts of new unionization on private sector employers 1984 2001 economic impacts of unionization on employers are difficult to estimate in the absence of large representative data on establishments with union status information estimates are also confounded by selection bias because unions could organize at highly profitable enterprises that are more likely to grow and pay higher wages using multiple establishment level data sets that represent establishments that faced organizing drives in the united states during 1984 1999 this paper uses a regression discontinuity design to estimate the impact of unionization on business survival employment output productivity and wages essentially outcomes for employers where unions barely won the election e g by one vote are compared with those where the unions barely lost the analysis finds small impacts on all outcomes that we examine estimates for wages are close to zero the evidence suggests that at least in recent decades the legal mandate that requires the employer to bargain with a certified union has had little economic impact on employers because unions have been somewhat unsuccessful at securing significant wage gains

inflation and productive activity in a multiple matching model of money abstract this paper investigates the relationship between money growth inflation and productive activity in a dynamic general equilibrium multiple matching framework where trade frictions are manifested by limited consumption variety productive activity and matching in the goods market are endogenized by a time allocation decision of work and search effort we find that a high degree of complementarity between participation in the labor and goods markets creates a channel by which inflation can positively influence production and output this feature arises when household preferences for consumption variety is sufficiently large and it can also lead to the multiplicity of monetary equilibria

the long run impact of exchange rate regimes on international tourism flows abstract notwithstanding the systematic inclusion of an exchange rate variable of some form in studies examining international tourism flows hardly any research has been carried out to test for a possible exchange rate regime effect drawing from recent advances in exchange rate regime classifications this paper begins to fill this gap by investigating the impact of exchange rate regimes on international tourism flows the study employs a system generalized methods of moments sys gmm estimation for tourist arrivals on a panel of 27 organization for economic co operation and development oecd and non oecd countries for the period 1980 2011 the results identify multiple exchange rate regime effects and support the importance of maintaining a relatively stable exchange rate to attract international tourist arrivals

technology policy for a world of skew distributed outcomes abstract this paper draws implications for technology policy from evidence on the size distribution of returns from eight sets of data on inventions and innovations attributable to private sector firms and universities the distributions are all highly skew the top 10 of sample members captured from 48 to 93 percent of total sample returns it follows that programs seeking to advance technology should not be judged negatively if they lead to numerous economic failures rather emphasis should be placed on the relatively few big successes to achieve noteworthy success with appreciable confidence a sizeable array of projects must often be supported the outcome distributions are sufficiently skewed that even with large numbers of projects it is not possible to diversify away substantial residual variability through portfolio strategies

the demand for international tourism in the mediterranean region the paper studies the demand for international tourism in the mediterranean region first a review of the most important attempts to model econometrically the demand for international tourism in the past is given followed by a formal presentation of the proposed theoretical model in particular a version of the almost ideal demand system aids is adopted and a description of the variables involved and their sources together with the estimation procedure are provided the diagrammatic analysis performed contributes to a better understanding of the evolution of the dependent variable over time the results with respect to the expenditure as well as to the own and cross price elasticities may be regarded as econometrically satisfactory and a reasonable economic explanation is given

interactions of commitment and discretion in monetary and fiscal policies we consider monetary scal interactions when the monetary authority is more conservative than the scal with both policies discretionary 1 nash equilibrium yields lower output and higher price than the ideal points of both authorities 2 of the two leadership possibilities scal leadership is generally better with scal discretion monetary commitment yields the same outcome as discretionary monetary leadership for all realizations of shocks but scal commitment is not similarly negated by monetary discretion second best outcomes require either joint commitment or identical targets for both authorities output socially optimal and price level appropriately conservative or complete separation of tasks jel e61 e63

fixed effect estimation of highly mobile production technologies we consider fixed effect estimation of a production function where inputs and outputs vary over time space and cross sectional unit we exploit variability in the spatial dimension to identify time varying individual effects without parametric assumptions on the effects while estimation is unbiased asymptotics along the spatial dimension allow estimation of robust standard errors and asymptotic normality of the marginal products also if inference on the estimates of the individual effects is warranted then spatial asymptotics provide asymptotic normality while precluding an incidental parameters problem caused by asymptotics along the time or crosssectional dimensions we apply our results to a production function of bottom trawler fishing vessels in the flatfish fisheries of the bering sea we find significant spatial variability of output catch which we exploit in estimation of a harvesting function we conclude that vessel individual effects did not change across the period 2002 to 2004 we apply the theory of ranking and selection to determine that individual effects are not statistically significant across vessels

theoretical developments in the light of macroeconomic policy and empirical research macroeconomics is surveyed with emphasis on the implications of the new classical and rational expectations critiques for the keynesian paradigm and the role of macro policies at the background are the main macro developments of the 1 970s and 1 980s as well as the specific lessons of recent high chronic inflation processes a synthesis is emerging in which the basic keynesian view of the existence of market and price coordination failures as well as room for pareto improving policy intervention are maintained at the same time the theoretical underpinnings are undergoing substantial change mainly due to a rational expectations reformulation

asymmetric effects of money supply shocks and trend inflation in recent years a number of empirical studies have presented evidence that money supply shocks have asymmetric effects that is unexpected negative changes in the money supply slow the economy more than unexpected positive changes accelerate the economy evidence of asymmetry was documented by cover 1992 for the postwar u s economy and his finding was confirmed by de long and summers 1988 morgan 1993 rhee and rich 1995 and karras 1996a b stimulated by these empirical works several attempts have been made to provide microeconomic foundations for the asymmetric effects of money supply shocks 1 among those theories this paper examines the one that focuses on asymmetric price adjustment and let us call it a sticky price theory money supply shocks will have asymmetric effects on real output if prices are less flexible downward than upward this sticky price theory was proposed by tsiddon 1993 ball and mankiw 1994 and caballero and engel 1992 by employing a menu cost model the above researchers show that positive trend inflation can produce the asymmetric effects of money supply shocks the logic of their theory is the following along with price adjustment costs positive trend infla

the impact of research grant funding on scientific productivity in this paper we estimate the impact of receiving an nih grant on subsequent publications and citations our sample consists of all applications unsuccessful as well as successful to the nih from 1980 to 2000 for standard research grants r01s both ols and iv estimates show that receipt of an nih research grant worth roughly 1 7 million leads to only one additional publication over the next five years which corresponds to a 7 percent increase the limited impact of nih grants is consistent with a model in which the market for research funding is competitive so that the loss of an nih grant simply causes researchers to shift to another source of funding

monopolistic competition and the effects of aggregate demand how important is monopolistic competition to an understanding of the effects of aggregate demand on output we ask the question at three levels can monopolistic competition by itself explain why aggregate demand movements affect output can it together with other imperfections generate effects of aggregate demand in a way that perfect competition cannot if so can it give an accurate account of the response of the economy to aggregate demand movements the answers are no yes and yes

do liquidity constraints and interest rates matter for consumer behavior evidence from credit card data this paper utilizes a unique new dataset of credit card accounts to analyze how people respond to changes in credit supply the data consist of a panel of thousands of individual credit card accounts from several different card issuers with associated credit bureau data we estimate both marginal propensities to consume mpcs out of liquidity and interest rate elasticities we also evaluate the ability of different models of consumption to rationalize our results distinguishing the permanent income hypothesis pih liquidity constraints precautionary saving and behavioral models we find that increases in credit limits generate an immediate and significant rise in debt counter to the pih the average mpc out of liquidity ddebt dlimit ranges between 10 14 the mpc is much larger for people starting near their limits consistent with binding liquidity constraints however the mpc is significant even for people starting well below their limit we show this response is consistent with buffer stock models of precautionary saving nonetheless there are other results that conventional models cannot easily explain e g why so many people are borrowing on their credit cards and simultaneously holding low yielding assets unlike most other studies we also find strong effects from changes in account specific interest rates the long run elasticity of debt to the interest rate is approximately 1 3 less than half of this elasticity represents balance shifting across cards with most reflecting net changes in total borrowing the elasticity is larger for decreases in interest rates than for increases which can explain the widespread use of temporary promotional rates the elasticity is smaller for people starting near their credit limits again consistent with liquidity constraints

bombs brains and science the role of human and physical capital for the creation of scientific knowledge i examine the role of human and physical capital for the creation of scientific knowledge i address the endogeneity of human and physical capital with two exogenous shocks the dismissal of scientists in nazi germany and world war ii bombings a 10 shock to human capital reduced output by 0 2 sd in the short run and the reduction persisted in the long run a 10 shock to physical capital reduced output by 0 05 sd in the short run and the reduction did not persist the dismissal of star scientists caused much larger reductions in output because they are key for attracting other successful scientists

exploring the cost efficiency of basic research funding in chemistry abstract in this paper i estimate the efficiency of a federal agency s basic research support for chemistry efficiency here means output per dollar of agency investment there are two outputs citations and apprentices those being trained by work on a project i use a random sample of 93 nsf chemistry projects to find determinants of efficiency the data on each project come from recorded agency investigator transactions required by nsf s standard operating procedures differences in efficiency result from differences in resources available to the projects the characteristics of researchers and characteristics of the research environment overall statistical modeling shows that there are strong interactions between inputs purely linear additive models show poorer results than models with interaction terms some inputs such as an investigator s scientific experience and the labor intensity of projects affect citation and apprentice efficiency positively but in an interactive way for example the marginal impact of investigator experience on citation efficiency depends on the level of labor intensity however some inputs considered highly important by funding agencies and the scientific community do not turn up as consistently significant e g the quality of departments the results suggest that the input output structure of research projects is complex thus quantitative analysis needs to be sensitive to the potential importance of interactions and non linearities

estimating the effect of financial aid offers on college enrollment a regression discontinuity approach an important problem faced by colleges and universities that of evaluating the effect of their financial aid offers on student enrollment decisions is complicated by the likely endogeneity of the aid offer variable in a student enrollment equation this article shows how discontinuities in an east coast college s aid assignment rule can be exploited to obtain credible estimates of the aid effect without having to rely on arbitrary exclusion restrictions and functional form assumptions semiparametric estimates based on a regression discontinuity rd approach affirm the importance of financial aid as an effective instrument in competing with other colleges for students

what determines aggregate returns to scale abstract this paper develops a unified framework that incorporates four features important in existing models with increasing returns fixed costs decreasing marginal costs product variety and market power when fixed costs are not allowed to vary and profits are imposed to be zero in every period only the degree of returns to variety determines the degree of aggregate increasing returns to scale when fixed costs respond to changes in aggregate activity or the zero profit condition does not hold in the short run aggregate returns depend not only on product variety but also on diminishing marginal costs or market power the degree of market power however does not affect input prices which are critical to determine the uniqueness of equilibrium

price rigidities and market structure conventional wisdom has it that a large part of the explanation of keynesian unemployment is the observed rigidities of wages and prices what has been lacking however is a satisfactory theory or conjunction of theories which explains how wages and prices can be at non market clearing levels the objective of this paper is to sketch out several alternative theoretical explanations of this phenomenon each in contrast with keynesian theory is consistent with the observation that as the economy goes into a recession real product wages do not increase and may in fact decrease all of the theories assume rational profit maximizing firms and all entail some important departure from the standard competitive paradigm the first three explanations represent minor adaptations of standard models

small menu costs and large business cycles a macroeconomic model of monopoly i introduction the conflict between modern neoclassical and traditional keynesian theories of the business cycle centers upon the pricing mechanism in neoclassical models prices are fully flexible they represent the continuous optimization of economic agents and the continuous intersection of supply and demand in keynesian models prices are often assumed to be sticky they do not necessarily equilibrate all markets at all times one of the reasons for the resurgence of the equilibrium approach to macroeconomics has been the absence of a theoretical underpinning for this keynesian price stickiness this note shows that sticky prices can be both privately efficient and socially inefficient the business cycle results from the suboptimal adjustment of prices in response to a demand shock to the extent that policy can stabilize aggregate demand it can mitigate the social loss due to this suboptimal adjustment in some keynesian models prices are simply exogenously fixed 2 in others agents must set their prices in advance of the transaction date the act of altering a posted price is certainly costly these costs include such items as printing new catalogs and informing salesmen of the new price yet these menu costs are small and therefore generally perceived as providing only a weak foundation for these fixed price models however this inference is flawed small menu costs can cause large welfare losses the claim that price adjustment costs are small does not rebut the claim that they are central to understanding economic fluctuations

increasing returns and the foundations of unemployment theory current approaches to macroeconomic theory divide roughly into two basic schools of thought one approach typically associated with rational expectations views the economy as basically at or near walrasian market clearing equilibrium in which case it becomes very difficult to explain away convincingly the undeniable persistence at times of involuntary unemployment another approach views the underemployed economy as being in a state of temporary fixed price disequilibrium in which case aside from having to repress suspicions that the essence of effective demand failure might not have to do with prices fixed at wrong values there is a lot of rationalising to be done about why profitable adjustments are so slow this paper argues that something like an internally consistent theory of steady state involuntary unemployment is possible and even plausible the cornerstone of this third approach is increasing returns to scale which blocks unemployed agents from breaking out of a low level equilibrium trap unless there is overall coordination or stimulation a simple model is presented which contains the basic ideas

does a common currency promote countries growth via trade and tourism the main aim of this study is to contribute to the debate on the effects of a common currency in particular the impact of a common currency on growth via trade and tourism is explored for a panel dataset which includes 179 countries as destination and 30 oecd countries as origin over the period 1995 2006 this research contributes to previous work in three ways i tourism is included as an additional channel for a common currency to promote growth ii the heterogeneity of countries is addressed by dividing the sample into three groups of countries by income and iii up to date data including the case of the euro are considered the results obtained suggest that a common currency strengthens economic growth by promoting not only international trade but also tourism

high tech r d subsidies estimating the effects of sematech abstract sparked by concerns about their shrinking market share 14 leading u s semiconductor producers with the financial assistance of the u s government in the form of 100 million in annual subsidies formed a joint r d consortium sematech in 1987 using compustat data on all u s semiconductor firms we estimate the effects of sematech on members r d spending profitability investment and productivity in so doing we examine two hypotheses the commitment hypothesis that sematech obligates member firms to spend more on high spillover r d and the sharing hypothesis that sematech reduces duplication of member r d spending whereas the commitment hypothesis provides a rationale for the government subsidies the sharing hypothesis does not we find that sematech induced members to cut their overall r d spending on the order of 300 million per year providing support for the sharing hypothesis

wage setting and the tax system theory and evidence for the united kingdom abstract this paper analyses the effects of a non linear tax system on wage bargaining the main conclusions are an increase in the marginal income or payroll tax rate reduces the pre tax wage in the isoelastic case an increase in the average tax rate increases the pre tax wage by more than the tax increase and a measure of the progressivity of the tax system residual income progression is a sufficient measure of the effect of the tax system on wage pressure empirical evidence is presented to support these propositions and the predictions of the model regarding the effect of recent changes to the u k tax system on the distribution of earnings discussed

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

taxation unemployment and growth dynamic welfare effects of green policies abstract this paper analyzes the effects of environmental tax reforms on a small open economy the labor market is characterized by union wage setting the carbon tax acts as an implicit tariff which gives rise to terms of trade gains the terms of trade effect together with the union wage setting leads to a positive relationship between the capital labor ratio and net foreign wealth in the short run the disinvestments in real and financial capital give temporary room for higher consumption and instantaneous utility the long run effect on instantaneous utility is more uncertain a strong double dividend may exist
