inflation and relative price variability in the euro area evidence from a panel threshold model the impact of inflation on relative price variability rpv generates an important channel for real effects of inflation this article provides first evidence on the empirical relation between inflation and rpv in the euro area stirred by the widespread use of inflation caps or target bands in monetary policy practice we are particularly interested in threshold effects of inflation in line with the predictions of monetary search models our results indicate that expected inflation significantly increases rpv only if inflation is either very low below 0 95 per annum p a or very high above 4 96 p a

is minsky s financial instability hypothesis valid in this article i reassess the validity of minsky s financial instability hypothesis and the main criticism about its internal coherence starting from this fundamental objection i study minsky s contribution within the scope of a highly simplified macro model it is shown that the financial instability hypothesis increasing debt ratios during economic expansion remains valid in numerous cases it appears amongst other things that a sufficient fall in the retention rate reinforces minsky s conclusions emphasising the destabilising role of shareholders in the distribution of net profits

marching to the beat of the drum the impact of the pace of life in us cities on entrepreneurial work effort founders face a variety of challenges while working to establish a viable start up in order to successfully overcome the many pressures that they face founders must make difficult choices about how to allocate their time and how much effort to exert in their ventures these founders are also embedded in a broader social context and their efforts are influenced by external conditions in this study we examine one particular social condition pace of life and its relationship on entrepreneurial work effort we argue that the pace of life in the region where founders launch and run their ventures affects their work effort over and above other individual and firm level characteristics we also argue that this direct relationship can strengthen or weaken depending on founding team size or entrepreneurial experience our longitudinal analyses of nearly 2600 us new ventures from 2004 to 2011 support our arguments our work advances prior research on the determinants of entrepreneurial work effort enhances the literature on social norms and entrepreneurial action and provides additional insights into the multilevel influences of entrepreneurial activity while entrepreneurs are commonly perceived as non conformists who march to the beat of their own drum we find evidence suggesting that regional pace of life actually sets the tempo for business owners and influences the amount of effort that they allocate to their ventures

risk and return in an equilibrium apt application of a new test methodology abstract we use an asymptotic principal components technique to estimate the pervasive factors influencing asset returns and to test the restrictions imposed by static and intertemporal equilibrium versions of the arbitrage pricing theory apt on a multivariate regression model the empirical techniques allow for fairly arbitrary time variation in risk premiums we find that the apt provides a better description of the expected returns on assets than the capital asset pricing model capm however some statistically reliable mispricing of assets by the apt remains

the higher returns to formal education for entrepreneurs versus employees how valuable is formal education for entrepreneurs income relative to employees and if the income returns to formal education are different for entrepreneurs vis a vis employees what might be a plausible explanation to explore these questions we analyze a large representative us panel we show that entrepreneurs have higher returns to formal education than employees we refer to this as the entrepreneurship returns puzzle we run post hoc analyses to explore a number of potential explanations of this puzzle indirectly our analysis indicates that the higher returns to formal education for entrepreneurs might be due to the fewer organizational constraints they face leading to more personal control over how to use their human capital compared to employees

monetary policy and investment dynamics evidence from disaggregate data we use disaggregated data on the components of private fixed investment pfi to estimate industry level responses of real investment and capital prices to unanticipated monetary policy the response functions derive from a restricted large scale var estimated over 1959 2007 our results point to significant cross sector heterogeneity in the behavior of pfi prices and quantities for assets belonging to the equipment category of fixed investment we find that quantities rather than prices absorb most of the fallout from a policy shock by contrast the price effects tend to be higher and the output effects lower for nonresidential structures

contract length monetary policy and exchange rate variability abstract this paper investigates the dependence of exchange rate variability on average contract length in the goods market when changes in the money supply are the driving force for movements in the exchange rate it is shown that in general an increase in average contract length will increase the volatility of the exchange rate we then discuss how changes in the money supply process affect average contract length besides providing an explanation for changes in the conditional variance of the exchange rate our results are interesting in the light of the changes in monetary control procedures implemented by the federal reserve board in october 1979 and the consequent increase in exchange rate volatility

steve jobs or no jobs entrepreneurial activity and performance among danish college dropouts and graduates are college dropouts successful entrepreneurs other than anecdotal evidence on illustrious college dropouts who managed to become self made billionaires there is only limited empirical evidence to answer this question this paper addresses this issue by investigating the relationship between college dropout or graduation and entrepreneurship activity as well as performance using information from the danish labor market register we identify college students whether these students graduate and if they registered a new venture we find that a larger share of dropouts starts a business but this reflects the endogeneity of the decision to exit from college on average becoming an entrepreneur does not allow dropouts to escape from their punishment in the labor market

using romer and romer s new measure of monetary policy shocks to identify the ad and as shocks this article re examines the series of exogenous federal funds rate ffr shocks created by romer and romer 2004 for the period 1969 01 1996 12 we hypothesize that if romer and romer have constructed a reasonable set of monetary policy shocks then including them in a small vector autoregression var should help to identify other structural shocks that affected the united states economy during their sample period using a sample period of 1971 01 1996 12 we are easily able to identify both an aggregate demand ad shock and an aggregate supply as shock without imposing any sign or long run restrictions we present historical decompositions that allow us to compare the relative importance of these shocks with that of the exogenous monetary policy shocks in explaining output fluctuations during the 1973 1975 1980 1984 and 1990 1991 business cycle episodes

housing finance and monetary policy we document three facts concerning how the structure of housing finance affects the monetary transmission mechanism first the characteristics of residential mortgage markets differ markedly across industrialized countries second the impact of monetary policy shocks to residential investment and house prices is significantly stronger in those countries with larger flexibility development of mortgage markets third the transmission to consumption is stronger only in those countries where mortgage equity release is common and mortgage contracts are predominantly of the variable rate type we then build a two sector dsge model with financial constraints to rationalize those facts

regional pay the public private sector pay differential abstractregional pay the public private sector pay differential regional studies this paper extends the debate on making public sector wages more responsive to those in the private sector the way in which the public private sector wage differential is calculated dramatically alters conclusions and far from there being substantial regional disparity in wages offered to public sector workers any differences are predominantly concentrated in london and the south east where public sector workers are significantly disadvantaged relative to private sector workers this has implications for staff recruitment and retention such findings question the need for regional market facing pay but highlight the necessity to revisit the london weighting offered to public sector workers

inflation inflation uncertainty and relative price dispersion evidence from bivariate garch m models abstract one potential real effect of inflation is its influence on the dispersion of relative prices in the economy menu cost models generally imply that higher trend inflation will increase price dispersion in contrast signal extraction models predict that increased inflation uncertainty will raise relative price dispersion existing empirical studies do not distinguish between these separate hypotheses we constuct a bivariate garch m model of inflation and relative price dispersion to test these differing explanations in a single model and find that inflation uncertainty dominates trend inflation as a predictor of relative price dispersion

estimating tax noncompliance with evidence from unaudited tax returns this article estimates the degree of tax noncompliance using evidence from unaudited tax returns measurements of noncompliance are derived from the relationship between reported charitable contributions and reported income from wages and salary as compared to alternative reported income sources such as self employment farm and other small business income assuming that the source of one s income is unrelated to one s charitable inclinations and that the ratio of true income to taxable income does not vary by income source any difference in the relationship between charitable contributions and the source of income can be attributed to relative underreporting by the individual we find that the implied amount of noncompliance is significant and that it varies by source of income as well as between positive and negative values of each type of income tax evasion creates horizontal inequity and if opportunities for evasion are correlated with income complicates the attempt to achieve vertical equity evasion also imposes economic costs because taxpayers expend resources to facilitate evasion and the tax agency expends resources to contain it the equity and efficiency implications of tax evasion and optimal policy to address it depend on its magnitude and nature which for obvious reasons is difficult to ascertain this article contributes to that effort by developing a new method for estimating the extent and nature of tax noncompliance based on evidence from unaudited tax returns this evidence is derived from the relationship between reported charitable contributions and reported taxable income from various sources such as wages and salaries selfemployment nonfarm small business and farm income and is based on the assumptions that the source of one s income is unrelated to one s charitable inclinations and that the ratio of true income to taxable income does not vary by income source we find that the implied amount of noncompliance on non wageand salary income is substantial and that it varies among these sources of income as well as between positive and negative values of each type of income on average reported positive self employment nonfarm small business and farm income must be multiplied by a factor of 1 54 4 54 and 3 87 respectively in order to obtain true income even those individuals who report zero income for a specific income source but file the schedule for that source are estimated to have true positive income finally those households that report negative schedule income may actually have greater true income than those households that report positive income

density dependence of entrepreneurial dynamics competition opportunity cost or minimum efficient scale this paper reports on a new examination of the well established negative effect of localized density on survival in established industries we attempt to discriminate between three competing but not necessarily mutually exclusive explanations resource competition variations in the opportunity costs of entrepreneurship and geographic variations in minimum efficient scale mes we construct a model of firm growth and survival in which each of these potential causes of density dependence has a transparent parametric effect and we derive six predictions that collectively allow for discriminating empirical tests empirical results using confidential geocoded data from the national longitudinal survey of youth consistently favor the opportunity cost mechanism this paper was accepted by toby stuart entrepreneurship and innovation

the time varying nairu and its implications for economic policy the nairu the unemployment rate consistent with a constant rate of inflation is estimated in this paper as a parameter allowed to vary over time value is determined in an econometric model where the inflation rate depends on its past values demand and supply shocks the nairu estimated for the gdp deflator varies over the past forty years within 5 4 to 6 5 percent its estimated value for the most recent quarter 1996 q2 is 5 6 percent the nairu has declined in recent years in response to global competition immigration other factors weakening labor s bargaining position and the rapidly declining prices of computers and other electronics

on the granger causality between median inflation and price dispersion the granger causal relationship between the size and dispersion of fluctuations in sub components of the us consumer price index cpi is examined using both in sample and out of sample tests and data from january 1968 to december 2008 strong in sample evidence is found for feedback between median inflation and price dispersion the evidence for granger causation from median inflation to price dispersion remains strong in out of sample testing but is less strong for granger causation in the opposite direction the implications of these results for the variety of price level determination models in the literature are discussed

the wage curve in russia 1995 2005 abstract this study draws on data collected for russia to investigate the existence of a wage curve over the period 1995 2005 when wage levels are expressed in u s dollars we find a highly significant negative wage elasticity coefficient close to 0 1

inflation and relative price variability new evidence for the united states this article provides new evidence on the empirical relationship between inflation and relative prices in the united states in line with the predictions of recent monetary search models we find that the impact of expected inflation on relative price variability rpv has disappeared during the recent period when inflation expectations have been stabilized on a low level endogenous break point tests are applied to identify the timing and to confirm the significance of the changing role of inflation for rpv the empirical findings are robust with respect to different price indices disaggregation levels and measurement concepts

the near optimality of mark up pricing mark up pricing policies result in a loss of profits compared to marginal pricing behavior these losses however are often very small even for large changes in the money supply but by adopting a simple pricing rule the firm does not have to forecast the future and avoids the informational and computational costs required to determine the profit maximizing price each period thus even if these costs are small mark up pricing policies may be optimal or approximately so at least for some firms in a macro model this is likely to imply large monetary non neutralities

inflation targeting as a monetary policy rule the purpose of the paper is to survey and discuss in ation targeting in the context of monetary policy rules the paper provides a general conceptual discussion of monetary policy rules attempts to clarify the essential characteristics of in ation targeting compares in ation targeting to other monetary policy rules and draws some conclusions for the monetary policy of the european system of central banks jel classi cation e42 e52

state dependent pricing inflation and welfare in search economies abstract we investigate the welfare effects of inflation in economies with search frictions and menu costs we first analyze an economy where there is no transaction demand for money balances money is a mere unit of account we determine a condition under which strictly positive inflation is desirable we relate this condition to a standard efficiency condition for search economies second we consider a related economy in which there is a transaction role for money in the absence of menu costs the friedman rule is optimal in the presence of menu costs the optimal inflation rate is negative for our numerical examples provided menu costs are small a deviation from the friedman rule can be optimal depending on the extent of the search externalities

inflation forecast targeting implementing and monitoring inflation targets abstract inflation targeting is shown to imply inflation forecast targeting the central bank s inflation forecast becomes an explicit intermediate target inflation forecast targeting simplifies both implementation and monitoring of monetary policy the weight on output stabilization determines how quickly the inflation forecast is adjusted towards the inflation target money growth or exchange rate targeting is generally inferior than inflation targeting and leads to higher inflation variability commitment to target rules may be better than commitment to instrument rules

cash flow investment and keynes minsky cycles this paper analyzes a dynamic model with 1 an investment function that emphasizes cash flow 2 a keynesian macroeconomic framework that determines cash flow endogenously 3 a dynamic labor market model that drives wage and price adjustments and 4 boundedly rational expectations simulations from the calibrated model generate endogenous cycles with characteristics described in hyman minsky s research the cycle arises from the link between investment interest rates debt service and cash flow the amplitude and frequency of the cycle are related to the importance of cash flow for investment the dynamics of inflation and the distribution of income

firms leverage ratio and the financial instability hypothesis an empirical investigation for the us economy 1970 2014 there are many minskian interpretations of how financial fragility builds up reflecting the unsolved tensions regarding the transition from micro to macro results in minsky s financial instability hypothesis fih using firm level and macroeconomic data to comply with the variety of fih s interpretations we empirically assess the relations between leverage and financial fragility in the us economy 1970 2014 to evaluate firms financial fragility we deploy minsky s scale from the financially sounder to the more fragile firms hedge speculative and ponzi the main findings are the following i the evolution of the aggregate leverage ratio does not account for the systemic financial fragility measured by the frequency of speculative and ponzi firms and ii within the biggest firms the leverage has increased along with the incidence of hedge financing and for the smallest firms group the opposite has happened we conclude that a positive relation between leverage and financial fragility cannot be deemed to be a general outcome

debt cycles instability and fiscal rules a godley minsky synthesis wynne godley and hyman minsky were two macroeconomists who saw the crisis coming this paper develops a simple macrodynamic model that synthesises some key perspectives of their analytical frameworks the model incorporates godley s financial balances approach and postulates that private sector s propensity to spend is driven by a stock flow norm the target net private debt to income ratio that changes endogenously via a minsky mechanism it also includes two fiscal rules a maastricht type fiscal rule according to which the fiscal authorities adjust the government expenditures based on a target net government debt ratio and a godley minsky fiscal rule which links government expenditures with private indebtedness following a counter cyclical logic the analysis shows that i the interaction between the propensity to spend and net private indebtedness can generate cycles and instability ii instability is more likely when the propensity to spend responds strongly to deviations from the stock flow norm and when the expectations that determine the stock flow norm are highly sensitive to the economic cycle iii the maastricht type fiscal rule is destabilising while the godley minsky fiscal rule is stabilising iv the paradox of debt can apply both to the private sector and the government sector

the impact of entrepreneurship education on entrepreneurship skills and motivation this paper analyzes the impact of a leading entrepreneurship education program on college students entrepreneurship skills and motivation using an instrumental variables approach in a difference in differences framework we exploit that the program was offered to students at one location of a school but not at another location of the same school location choice and thereby treatment is instrumented by the relative distance of locations to parents place of residence the results show that the program does not have the intended effects the effect on students self assessed entrepreneurial skills is insignificant and the effect on the intention to become an entrepreneur is even negative

sectoral variability and the foundations of optimal inflation rate abstractthe recent monetary search models argue that the real effects of inflation on economic activity can be gauged through relative price variability rpv our study uses a large panel data of

estimates of the black economy based on consumer demand approaches we propose a consumer demand system approach to estimating the size of the black economy where alternative hypotheses affecting the empirical results can be tested in a nested framework this approach allows for the estimation of the under reporting of household income from various sources dispensing with the need to use arbitrary criteria to classify households by their main source of income it also avoids potential bias in black economy estimates arising from mistaking preference heterogeneity substitution as income effects we illustrate these arguments by estimating the extent to which self employment income in the uk is underreported using parametric and nonparametric techniques the black economy broadly defined as the economic activities that are hidden from public authorities to avoid taxation has recently received increased attention in the literature due to arguments that the rising tax burden and state regulation is driving economic activity underground tanzi and schuknecht 1997 enste and schneider 1998 the usefulness of attempts to estimate the size of the black economy however is a controversial issue the sceptics emphasise the difficulties associated with the precise definition of black economy activities and point to the widely different estimates of the size of these activities resulting from alternative methods dixon 1999 tanzi 1999 thomas 1999 authors approaching the subject in an optimistic frame of mind emphasise positive aspects of estimating the size of the black economy such as the correct measurement of gdp and other macroeconomic variables e g employment and the design of policy and econometric models bhattacharyya 1999 giles 1999 the controversy on estimation issues however does not subtract from the widespread concern about the undesired consequences of the black economy undeclared economic activities reduce the tax base thereby undermining the financing of public goods and social protection a country trying to curtail the loss of tax revenue by raising tax rates can create a vicious cycle as this reinforces the incentive not to declare economic activities to the public authorities high tax rates have a distorting effect resulting in inefficient allocation of resources due to unequal opportunities and willingness to evade in different sectors of the economy and can undermine the ability of the country to compete internationally distortions in the labour market can also arise because individuals working in the black economy may have difficulty in moving from one job to another furthermore in countries where health pension and other social security payments are not universal individuals working in the black economy and their families are outside the

let s get real a factor analytical approach to disaggregated business cycle dynamics this paper develops a method for analysing the dynamics of large cross sections based on a factor analytic model we use law of large numbers arguments to show that the number of common factors can be determined by a principal components method the economy wide shocks can be identified by means of simple structural var techniques and that the parameters of the unobserved factor model can be estimated consistently by applying ols equation by equation we distinguish between a technological and a non technological shock identification is obtained by minimizing the negative realizations of the technology shock empirical results on 4 digit industrial output and productivity for the u s economy from 1958 to 1986 show that 1 at least two economy wide shocks both having a long run effect on sectoral output are needed to explain the common dynamics 2 although the technological shock accounts for at least 50 of the aggregate dynamics of output it cannot by itself explain dynamics at business cycle frequencies 3 sector specific shocks explain the main bulk of total variance but generate mainly high frequency dynamics 4 both the technological and the non technological component of output show a peak for positive sectoral comovements of output at business cycle frequencies 5 technological shocks are strongly correlated with the growth rates of the investment in machinery and equipment sectors and their inputs many interesting questions about cyclical fluctuations and economic growth can be answered only by studying the dynamic behaviour of sectoral variables when data contain information on time for a large cross section of sectors traditional econometric techniques used in the macroeconomic literature such as vector autoregressive var and vector autoregressive moving average varma models are not appropriate since they require the estimation of too many parameters this is why new methods which allow for the reduction of the parameter space need to be developed the objective of this paper is both methodological and descriptive at the methodological level we develop a simple framework for the dynamic analysis of large cross sections the basic model is a dynamic factor analytic model as in sargent and sims 1977 the sectoral variables are decomposed into two unobservable components a common component driven by macroeconomic shocks and a purely sectoral component when

the second theorem of the second best abstract this paper interprets many results from the literature on incentive compatibility and cost benefit analysis as illustrations of a second theorem of the second best the theorem states that if there exists any restriction on transactions required for first best efficiency then there is no presumption that a social welfare maximum entails equal marginal social utilities of income across individuals one reason is that incentive constraints shift with redistributions of wealth so that redistributions have an instrumental role in relaxing constraints that make the economy second best two examples relate such wealth effects to countervailing incentives and hostage taking

output and welfare effects of inflation with costly price and quantity adjustments there exists by now a burgeoning literature concerned with the consequences of a fixed cost of price adjustment due to this cost a monopolistic firm does not necessarily adjust its price even though the current price deviates from the price that would maximize the firm s current profit as a result the production generally differs from what it would be in the absence of a menu cost with the effect of inflation on the average output and welfare under monopolistic competition being ambiguous and depending in a complicated way on the profit and demand functions 1 however one strong result holds unambiguously for all profit and demand functions at low inflation rates the average output and welfare are above their levels at full price stability where firms charge the static monopoly price 2 the driving force is that discounting makes a firm more concerned with its real profits earlier in a period with a constant nominal price than with its real profits later in the period in fact as the inflation rate approaches zero the firm s initial real price converges to the profit maximizing real price while the terminal real price converges to a smaller real price at low inflation rates therefore a firm s price is most of the time below the price that would maximize the current profit since output and welfare under monopolistic competition are inversely related to price average output and welfare are higher than under full price stability the inevitable conclusion is that the economy benefits from a little bit of inflation a critical assumption underlying this result is that firms can continuously adjust their production to satisfy demand so while the menu cost literature explicitly assumes that there is a small fixed cost incurred at each price adjustment it also implicitly assumes that it is costless to continuously adjust the quantity of output 3 this is however a questionable assumption there is some empirical evidence indicating the existence of a cost of quantity adjustment part of which is fixed in that it does not depend on the size of the adjustment 4 the cost of quantity adjustment stems from the need to rearrange and reorganize the factor inputs for the new level of production and includes managerial time and effort a fixed cost of quantity adjustment rules out any continuous adjustment of the production to satisfy the increasing demand that results from a decreasing real price within a period with a constant nominal price under the reasonable assumption that the menu cost does not exceed the fixed cost of quantity adjustment 5 in an inflationary environment a firm chooses to adjust its nomi

other people s money cash in advance microfoundations for optimal currency areas abstract in the traditional theory of optimal currency areas there are potential gains for stabilization policy with an independent exchange rate and money because rigidity of prices causes an inadequate response of relative prices to shocks recent empirical work using modern extensions of the mundell fleming model based on nominal contracts has supported this view this paper examines whether there is support for it in a classical representative agent model of linked open economies and finds that there is the result comes from the cash in advance constraint under which the household faces an inevitable delay between working receiving cash and being able to spend the proceeds this delay is the cash in advance analogue of the nominal price rigidity in the optimal currency area models

inflation price dispersion and market integration through the lens of a monetary search model monetary search theory implies that the real effects of inflation via its impact on price dispersion depend on the level of search costs and thus on the level of market integration for less integrated markets the inflation price dispersion nexus is predicted to be asymmetrically v shaped which results in an optimal inflation rate above zero for highly integrated markets with low search costs however the impact of inflation on price dispersion should only be small using price data of the european union member states this paper is the first that tests and confirms these predictions of monetary search theory

output effects of inflation with fixed price and quantity adjustment costs i introduction there is convincing evidence that fixed costs of price adjustment may be large levy et al 1997 found such costs to be 0 7 of a firm s revenue and zbaracki et al 2004 found them to be 1 22 in the presence of fixed costs of price adjustment a monopolistic firm does not adjust its nominal price continuously with the result that the real price and output generally deviate from their static monopoly level at low inflation rates the average output is higher than the static monopoly output if there is positive discounting danziger 1988 and depends on higher order derivatives of the profit and demand functions if there is no discounting benabou and konieczny 1994 1 most of the literature assumes that only price adjustments are costly while output can be continuously adjusted without cost however bresnahan and ramey 1994 document that there may be large fixed costs of quantity adjustments relatedly many publications show that adjusting labor and capital inputs involves significant fixed costs 2 such costs may derive from loss of organizational capital baily et al 2001 jovanovic and rousseau 2001 as well as from job protection rules severance pay and legal and administrative complications in a framework with both price and quantity adjustment costs andersen 1995 and andersen and toulemonde 2004 demonstrate that only intermediate size shock but not large or small shocks may affect output for a constant inflation rate danziger 2001 shows that a firm s permanent production decreases with inflation at low inflation rates if discounting is positive and danziger and kreiner 2002 that output capacity decreases with inflation if the elasticity of demand is constant and there is no discounting see also danziger 2003 the purpose of this article is to provide a simple general characterization of the output effects of a constant inflation rate if both price and quantity adjustments involve fixed costs it is assumed that quantity adjustments are at least as costly as price adjustments which implies that a firm s production is held constant at a permanent level 3 each firm then keeps its nominal price unchanged in periods of equal length and the nominal price is adjusted so that the initial real price is the same in each period thus a firm s optimal strategy consists of the initial real price the duration of the periods with unchanged nominal price and the permanent level of production the article shows that in the absence of discounting the effect of inflation on the aggregate production depends on how fast firms marginal real revenue decreases with demand and that this effect is fully determined by the elasticity of the marginal real revenue with respect to demand thus aggregate production decreases with inflation if the elasticity of the marginal real revenue always exceeds minus unity increases with inflation if the elasticity of the marginal real revenue is always less than minus unity and is invariant to inflation if the elasticity of the marginal real revenue always equals minus unity several studies have found that the comovement between output and prices is typically negative in the long run cooley and ohanian 1991 den haan 2000 den haan and sumner 2004 fiorito and kollintzas 1994 within the framework of the present model the negative comovement indicates that the empirically relevant situation is when the elasticity of the marginal real revenue always exceeds minus unity this will be the case among others if demand functions exhibit a constant price elasticity less than minus unity as assumed in danziger and kreiner 2002 ii the model consider an economy with a unit continuum of identical consumers and a unit continuum of monopolistic firms producing differentiated perishable products each firm and its product are indexed by i which is uniformly distributed on 0 1

estimates of the economic returns to schooling from a new sample of twins this paper uses a new survey to contrast the wages of genetically identical twins with different schooling levels multiple measurements of schooling levels were also collected to assess the effect of reporting error on the estimated economic returns to schooling the data indicate that omitted ability variables do not bias the estimated return to schooling upward but that measurement error does bias it downward adjustment for measurement error indicates that an additional year of schooling increases wages by 12 to 16 percent a higher estimate of the economic returns to schooling than has been previously found copyright 1994 by american economic association

does compulsory school attendance affect schooling and earnings we establish that season of birth is related to educational attainment because of school start age policy and compulsory school attendance laws individuals born in the beginning of the year start school at an older age and can therefore drop out after completing less schooling than individuals born near the end of the year roughly 25 percent of potential dropouts remain in school because of compulsory schooling laws we estimate the impact of compulsory schooling on earnings by using quarter of birth as an instrument for education the instrumental variables estimate of the return to education is close to the ordinary least squares estimate suggesting that there is little bias in conventional estimates every developed country in the world has a compulsory schooling requirement yet little is known about the effect these laws have on educational attainment and earnings 1 this paper exploits an unusual natural experiment to estimate the impact of compulsory schooling laws in the united states the experiment stems from the fact that children born in different months of the year start school at different ages while compulsory schooling laws generally require students to remain in school until their sixteenth or seventeenth birthday in effect the interaction of school entry requirements and compulsory schooling laws compel students born

is work special justice and the distribution of employment i investigate from an egalitarian welfarist standpoint the issue of whether state guaranteed employment should be offered as a matter of right to able bodied poor citizens who suffer chronic or persistent unemployment an affirmative answer is defended one consideration supporting this right to work is that provision of transfer aid in the form of jobs rather than cash screens nonneedy bohemians from the class of beneficiaries the main conclusion of the essay is defended from one objection based on efficiency wage models of the labor market and from another based on the alleged impossibility of maintaining the self respect and self esteem of able bodied individuals who fail to earn their own keep independently in a market economy

macrodynamics of debt regimes financial instability and growth this paper develops a post keynesian dynamic model of capacity utilisation and growth in which the supply of credit money is endogenous and firms debt position and thus the financial fragility of the economy a la hyman minsky is explicitly modelled the interest rate is set by banks as a markup over a base rate exogenously determined by the monetary authority the banking markup varies with changes in capacity utilisation while the debt ratio varies with changes in the rates of interest capital accumulation and growth regarding dynamics it is shown the possibility of relating the stability properties of a system with the interest rate and the debt ratio as state variables to the prevailing minskyan regime hedge speculative or ponzi

on inflation and real price variability this paper studies the consequences of costly price adjustments for the variability of real prices accompanying inflation for constant elasticity demand and cost of production it is shown that a higher demand a lower cost of production or a lower cost of price adjustment leads to less intertemporal variability of real prices if the marginal cost of production does not increase too fast then the average real price is less than the real price that would prevail in the absence of inflation additionally a higher demand a lower cost of production or a lower cost of price adjustment leads to a higher level of real prices

search in the product market and the real business cycle empirical evidence suggests that most firms operate in imperfectly competitivemarkets we develop a search matching model between wholesalers and retailers firms face search costs and form long term relationships price bargain results in both wholesaler and retailer markups depending on firms relative bargaining power we simulate the model to explore the role of product market search frictions in business cycles we show that the way search costs are modelled is crucial to provide a realistic picture of firms business environment and improve the cyclical properties of an otherwise standard real business cycle model

returns to education evidence from u k twins we use a new sample of uk female identical twins to estimate private economic returns to education we report findings in three areas first we use identical twins to control for family effects and genetic ability bias and the education reported by the other twin to control for schooling measurement error our estimates suggest a return to schooling for uk females of about 7 7 second we investigate within twin pair ability differences by examining within twin pair and between family correlations of education with observable correlates of ability including birthweight ability tests and reading scores our findings suggest lower ability bias in within twin pair regressions than pooled regressions third using data on twins smoking we show smoking reflects family background and using it as an instrument exacerbates ability bias this abstract was borrowed from another version of this item

synchronization of price changes by multiproduct firms evidence from canadian newspaper prices abstract using data for canadian daily newspapers we find that price changes of papers owned by the same firm are synchronized on the other hand independently owned newspapers do not appear to change their prices together

thanks for nothing not for profits and motivated agents we re examine the labor donation theory of not for profits and show that these organizations may exist not necessarily because motivated workers prefer to work in them or that they dominate for profits in terms of welfare but because the excess supply of motivated workers makes the non profit form more attractive to managers we show that if firms had to compete for motivated workers then not for profit firms would be competed out by for profit firms therefore in the choice between not for profit and for profit provision other than incentive problems the distribution of rents between management and workers and consequently the relative scarcity of motivated workers may play an important role

on relative price variability and hyperinflation abstract during the chinese hyperinflation 1946 1 1949 4 both anticipated inflation were found to influence relative price variability positively the non neutral effect of anticipated inflation rejects the conventional lucas island model while lending empirical support to the price adjustment cost theory

minsky s induced investment and business cycles this paper reviews the recently published phd thesis of hyman p minsky summarising its main contributions to methodology and microeconomics these are aspects of economics with which minsky is not usually associated but which lie at the foundation of his later work they include critical remarks on cambridge economics the paper then draws out some antecedents of minsky s ideas in the work of henry simons and highlights the marshallian monetary analysis that he adopted it is argued that this analysis is incompatible with the kaleckian theory of profits that minsky was later to adopt

minsky models a structured survey minsky s ideas have recently gained prominence in the mainstream as well as in the heterodox literature however there exists no agreement upon the formal presentation of minsky s insights the aim of this paper is to survey the literature and identify differences and similarities in the ways through which minskyan ideas have been formalised we distinguish between the models that focus on the dynamics of debt or interest with no or a secondary role for asset prices and the models in which asset prices play a key role in the dynamic behaviour of the economy within the first category of models we make a classification between i the kalecki minsky models ii the kaldor minsky models iii the goodwin minsky models iv the credit rationing minsky models v the endogenous target debt ratio models and vi the minsky veblen models within the second category of models we distinguish between i the equity price minsky models and ii the real estate price minsky models key limitations of the models and directions for future research are outlined

the returns to education microeconomics in this paper we focus on education as a private decision to invest in human capital and the estimation of the rate of return to that private investment while the literature is replete with studies that estimate the rate of return using regression methods where the estimated return is obtained as the coefficient on a years of education variable in a log wage equation that contains controls for work experience and other individual characteristics the issue is surrounded with difficulties we outline the theoretical arguments underpinning the empirical developments and show that the evidence on private returns to the individual is compelling despite some of these issues surrounding the estimation of the return to schooling our evidence based on estimates from a variety of datasets and specifications is that there is an unambiguously positive effect on the earnings of an individual from participation in education moreover the size of the effect seems large relative to the returns on other investments

optimal price setting with observation and menu costs we study the price setting problem of a firm in the presence of both observation and menu costs in this problem the firm optimally decides when to collect costly information on the adequacy of its price an activity which we refer to as a price review upon each review the firm chooses whether to adjust its price subject to a menu cost and when to conduct the next price review this behavior is consistent with recent survey evidence documenting that firms revise prices infrequently and that only a few price revisions yield a price adjustment the goal of the paper is to study how the firm s choices map into several observable statistics depending on the level and relative magnitude of the observation vs the menu cost the observable statistics are the frequency of price reviews the frequency of price adjustments the size distribution of price adjustments and the shape of the hazard rate of price adjustments we provide an analytical characterization of the firm s decisions and a mapping from the structural parameters to the observable statistics we compare these statistics with the ones obtained for the models with only one type of cost the predictions of the model can with suitable data be used to quantify the importance of the menu cost vs the information cost we also consider a version of the model where several price adjustment are allowed between observations a form of price plans or indexation we find that no indexation is optimal for small inflation rates

the effects of human capital interventions on entrepreneurial performance in industrialized countries this paper provides a systematic review of studies on the effects of human capital interventions on entrepreneurial performance in industrialized countries we identify 21 experimental and quasi experimental studies published before september 2018 these studies examine the effects of business training formal education and entrepreneurship education their performance outcomes include firm profits firm size and entrepreneurial earnings the main finding across these studies is that these interventions do not have statistically significant effects formal education is the only exception showing positive effects on firm profits and entrepreneurial earnings yet these effects are small in magnitude evidence is inconclusive regarding effect duration these findings stand in stark contrast to correlational studies which tend to find large positive correlations between human capital interventions and entrepreneurial performance we therefore conclude that correlational studies tend to overestimate the benefits of human capital interventions moreover our estimates show that the interventions are associated with moderately low additionality

modelling inflation shifts and persistence in tunisia perspectives from an evolutionary spectral approach this article examines the dynamic characteristics of the inflation rate in tunisia over the last two decades and particularly following the onset of the arab spring in 2010 which causes distortions in this country s monetary policy we focus on the two specific dimensions of the tunisian inflation rate inflation regimes and persistence we tackle this issue by adopting an evolutionary spectral approach initially proposed by priestley and tong 1973 our main findings indicate a stable inflation regime in the last 10 years with an average inflation rate of around 5 5 it is also found that the tunisian inflation experienced a high degree of inertia which reflects its gradual responses to shocks we also discuss the policy implications of these results which typically require policy makers to implement sound institutional reforms to reduce inflation

the imprint of labor markets on entrepreneurial performance abstract using the 1979 2010 waves of the national longitudinal survey of youth our study tracks the earnings of individual entrepreneurs from the beginning of their entrepreneurial careers examining the effects of labor markets on their earnings trajectory results show that apart from self selection labor markets impose a penalty on the initial earnings of entrepreneurs who start a business in adverse economic conditions a disadvantage that persists for up to a decade we also identify two factors expected to alleviate the imprinting effect of labor markets migration outside the imprinting environment and serial entrepreneurship

the more the merrier the effect of family size and birth order on children s education there is an extensive theoretical literature that postulates a tradeoff between child quantity and quality within a family however there is little causal evidence that speaks to this theory using a rich dataset on the entire population of norway over an extended period of time we examine the effects of family size and birth order on the educational attainment of children while we find a negative correlation between family size and children s education when we include indicators for birth order and or use twin births as an instrument family size effects become negligible in addition birth order has a significant and large negative effect on children s education we also study adult earnings employment and teenage childbearing and find strong evidence for birth order effects with these outcomes particularly among women these findings suggest the need to revisit economic models of fertility and child production focusing not only on differences across families but differences within families as well

some tests on the effects of inflation targeting in new zealand canada and the uk abstract there is no empirical evidence that inflation targeting has changed macroeconomic variables in the unrestricted var context there are two possible interpretations for this result one is that inflation targeting may truly have no significant impacts on macroeconomic variables the alternative scenario might be that the number of parameters in our model is so large relative to the number of observations that our tests do not have enough power to reject the null hypothesis of no structural changes further statistical investigations are desirable as more data become available and alternative models are devised

inflation and relative price variability abstract theoretical explanations of the inflation relative price variability relationship are often observationally equivalent this paper compares two theoretical models menu costs and imperfect information the microfoundations of the models are used to generate new testable differences between the theories

are entrepreneurship and cognitive skills related some international evidence do national differences in cognitive skills cs predict a nation s likelihood of generating high quality entrepreneurs who create and expand high value businesses we answer this question by estimating cross country regressions that use the acs and szerb global entrepreneurship development index gedi and a measure of national cs after including conventional controls we find for a sample of 60 countries that our measure of cs robustly predicts the gedi unconditional correlation 0 65 standardized beta 0 42 an index that gives weight to both entrepreneurial attitudes within a nation and the institutional and economic prerequisites for creating high value high growth firms we find that this result also holds for an alternative measure of entrepreneurship

a simplified stock flow consistent dynamic model of the systemic financial fragility in the new capitalism in the last few years many financial analysts and heterodox economists but even some dissenters among orthodox economists have referred to the contribution of hyman p minsky as fundamental to understanding the current crisis however it is well known that the traditional formulation of minsky s financial instability hypothesis shows serious internal logical problems furthermore minsky s analysis of capitalism must be updated on the basis of the deep changes which during the last three decades have concerned the world economy in order to overcome these theoretical and empirical troubles this paper first introduces the reader to the mechanics of the financial instability theory according to the formulation of the traditional minskian literature section 2 second it shows why minsky s theory cannot be regarded as a general theory of the business cycle section 3 third the paper attempts to supply a simplified but consistent re formulation of minsky s theory by inter breeding it with inputs coming from the new cambridge theories and the current formal minskian literature the aim of this is to analyze the impact of both capital asset inflation and consumer credit on the financial soundness of the non financial business sector sections 4 7 some concluding remarks are provided in the last part of the paper section 8

omitted ability bias and the increase in the return to schooling over the 1980s there were sharp increases in the return to schooling estimated with conventional wage regressions we explore whether the relationship between ability and schooling changed over this period in ways that would have increased the schooling coefficient in these regressions our empirical results reject the hypothesis that an increase in the bias of the schooling coefficient due to a change in the relationship between ability and schooling has contributed to observed increases in the return to schooling we also find that the increase in the schooling return has occurred for workers with relatively high levels of academic ability

transition to entrepreneurship from the public sector predispositional and contextual effects studies of career dynamics implicitly claim that government employees are not entrepreneurial utilizing longitudinal data from the u s panel study for income dynamics we investigate the reasons for the low rate of entrepreneurship from the public sector we conjecture that it is due to labor market matching processes and the bureaucratic nature of public organizations and bureaucratization of individuals our life course analysis identifies labor market matching as a major determinant nonentrepreneurial types choose public sector employment we also uncover tenure and context effects which decrease and increase the hazard rate of entrepreneurial exit respectively whereas the former effect points toward adaptation and internal labor market sorting the latter draws attention to exits due to frustration

estimating average and local average treatment effects of education when compulsory schooling laws really matter the change to the minimum school leaving age in the united kingdom from 14 to 15 had a powerful and immediate effect that redirected almost half the population of 14 year olds in the mid twentieth century to stay in school for one more year the magnitude of this impact provides a rare opportunity to a estimate local average treatment effects late of high school that come close to population average treatment effects ate and b estimate returns to education using a regression discontinuity design instead of previous estimates that rely on difference in differences methodology or relatively weak instruments comparing late estimates for the united states and canada where very few students were affected by compulsory school laws to the united kingdom estimates provides a test as to whether instrumental variables iv returns to schooling often exceed ordinary least squares ols because gains are high only for small and peculiar groups among the more general population i find instead that the benefits from compulsory schooling are very large whether these laws have an impact on a majority or minority of those exposed

examining the formation of human capital in entrepreneurship a meta analysis of entrepreneurship education outcomes abstract effective human capital formation through the medium of entrepreneurship education and training eet is of increasing concern for governments as eet is growing rapidly across the world unfortunately there is a lack of consistent evidence showing that eet helps to create more or better entrepreneurs we undertake the first quantitative review of the literature and in the context of human capital theory find that there is indeed support for the value of eet based on 42 independent samples n 16 657 we find a significant relationship between eet and entrepreneurship related human capital assets r w 217 and entrepreneurship outcomes r w 159 the relationship between eet and entrepreneurship outcomes is stronger for academic focused eet interventions r w 238 than for training focused eet interventions r w 151 we find evidence of heterogeneity in many of our correlations and recommend that future studies examine potential moderators to more clearly delineate eet effect sizes we also find a number of methodological weaknesses among the studies analyzed and that those studies with lower methodological rigor are overstating the effect of eet recommendations to improve the quality of future work in the field are provided

relative price and inflation variability in a simple consumer search model there is a large empirical literature on the effect of aggregate inflation on both price level dispersion relative price variability rpv and inflation rate dispersion relative inflation variability riv across goods or locations early empirical work of riv has an explicit theoretical foundation in signal extraction models however recent empirical work on rpv has produced results inconsistent with signal extraction models in particular while riv is increasing in the absolute value of inflation shocks rpv is a negative monotonic function of inflation shocks we show that consumer search theory offers a potential explanation for these apparently contradictory observations

macroeconomic forecasting using diffusion indexes this article studies forecasting a macroeconomic time series variable using a large number of predictors the predictors are summarized using a small number of indexes constructed by principal component analysis an approximate dynamic factor model serves as the statistical framework for the estimation of the indexes and construction of the forecasts the method is used to construct 6 12 and 24 monthahead forecasts for eight monthly u s macroeconomic time series using 215 predictors in simulated real time from 1970 through 1998 during this sample period these new forecasts outperformed univariate autoregressions small vector autoregressions and leading indicator models

the nairu unemployment and monetary policy this paper examines the precision of conventional estimates of the nairu and the role of the nairu and unemployment in forecasting inflation the authors find that although there is a clear empirical phillips relation the nairu is imprecisely estimated forecasts of inflation are insensitive to the nairu and there are other leading indicators of inflation that are at least as good as unemployment this suggests deemphasizing the nairu in public discourse about monetary policy and instead drawing on a richer variety of leading indicators of inflation

short and medium term financial real cycles an empirical assessment 2019 elsevier ltd theories such as minsky s financial instability hypothesis or new keynesian financial accelerator models assign a key role to financial factors in business cycle dynamics we propose a simple var based estimation framework to examine some of the financial real interaction mechanisms that are at the core of these theories we examine cycle frequencies in seven oecd countries over the period 1970 2015 and find that output contains short and medium business cycle frequencies while interest rates business debt and household debt exhibit short medium and long cycles respectively we find robust evidence for financial real interaction mechanisms i at high frequencies between interest rates and gdp in australia and the usa and ii at medium frequencies between business debt and gdp in canada and great britain the effect of interest rates and debt seems to operate via investment rather than consumption we find no evidence for an interaction mechanism between household debt and gdp our results provide support for minskyan and financial accelerator models in which output interacts with interest rates or corporate debt
