addressing leakage in the eu ets border adjustment or output based allocation the eu ets has been criticised for threatening the competitiveness of european industry and generating carbon leakage i e increasing foreign greenhouse gas emissions two main options have been put forward to tackle these concerns border adjustments and output based allocation i e allocation of free allowances in proportion to current production we compare various configurations of these two options as well as a scenario with full auctioning and no border adjustment against this background we develop a model of the main sectors covered by the eu ets electricity steel cement and aluminium we conclude that the most efficient way to tackle leakage is auctioning with border adjustment which generally induces a negative leakage a spillover this holds even if the border adjustment does not include indirect emissions if it is based on eu rather than foreign specific emissions or for some values of the parameters if it covers only imports another relatively efficient policy is to combine auctioning in the electricity sector and output based allocation in exposed industries especially if free allowances are given both for direct and indirect emissions i e those generated by the generation of the electricity consumed although output based allocation is generally less effective than border adjustment to tackle leakage it is more effective to mitigate production losses in the sectors affected by the ets which may ease climate policy adoption c 2011 elsevier b v all rights reserved

the inflation tax in a real business cycle model money is incorporated into a real business cycle model using a cash in advance constraint the model economy is used to analyze whether the business cycle is different in high inflation and low inflation economies and to analyze the impact of variability in the growth rate of money in addition the welfare cost of the inflation tax is measured and the steady state properties of high and low inflation economies are compared

carbon leakage and capacity based allocations is the eu right competitiveness and carbon leakage are major concerns for the design of co2 emissions permits markets in the absence of a global carbon tax and of border carbon adjustments output based allocation is a third best solution and is actually implemented australia california new zealand the eu has followed a different route free allowances are allocated to existing or new capacities in proportion to a benchmark independent of actual production this paper compares these two schemes in a formal setting and shows that the optimal one is in fact a combination of both schemes or output based allocation alone if uncertainty is limited a key assumption of our analysis is that the short term import pressure depends both on the existing capacities and the level of demand which is typical in capital intensive and internationally traded sectors a calibration of the model is used to discuss the eu scheme for the cement sector in the third phase of the eu ets 2013 2020 this allows for a quantification of various policies in terms of welfare investment production company profits public revenues and leakage

long term growth and short term economic instability when learning by doing is at the origin of growth the long run growth rate should be negatively related to the amplitude of the business cycle if human capital accumulation is increasing and concave in the cyclical component of production empirical evidence strongly supports this nding for industrialized countries and european regions using the standard control variables we nd that countries and regions that have a higher standard deviation of growth and of unemployment have lower growth rates the result does not come from an e ect of instability on investment the negative relation however does not hold for non industrialized countries for which learning by doing may not to be the main engine of growth 2000 elsevier science b v all rights reserved jel classixcation o40 e32

should a carbon tax be differentiated across sectors abstract if some but not all countries are cooperating to reduce co2 emissions one could make the following argument a high carbon tax for carbon intensive tradeable sectors in the cooperating countries will reduce the production of goods from these sectors and therefore co2 emissions in the cooperating countries however this will to a large extent be counteracted by increased production of such goods in the countries that have no climate policy and since it is only total co2 emissions from all countries that are relevant for the climate there is no point in a policy that simply relocates co2 emissions from the cooperating countries to the countries that have no climate policy according to this line of reasoning carbon intensive tradeable sectors should thus face a lower carbon tax than other sectors of the economy this paper shows that a carbon tax should not be differentiated across sectors in the economy provided one can use import and export tariffs on all traded goods it is also shown that such a differentiation of carbon taxes is optimal for the cooperating countries if they are prevented from using tariffs on the traded goods however informational or political factors constraining the use of tariffs are likely also to constrain the possibility of differentiating carbon taxes between sectors

cyclical and causal relations between real wages and employment in the eu this paper analyses and compares the joint behaviour of real wages and employment over the business cycle in the european union eu economies using both annual and quarterly data since 1960 further investigation of the cointegrating properties and the existence of causal effects in the real wage employment relation is undertaken by employing appropriate var models the evidence suggests weak procyclical or acyclic behaviour of real wages relative to cyclical employment in the quarterly data and stronger procyclicality in the annual data thus confirming the dunlop tarshis result for the majority of the eu economies with a few exceptions no cointegrating relations were detected while the granger causality tests suggest either weak or lack of unidirectional causality finally the sensitivity analysis showed that the filtering method has not much influence on the results but the choice of deflator may overturn them in certain cases

business cycles theory evidence and policy implications this paper looks at recent advances in the study of aggregate fluctuations the emphasis is on three prominent areas of research the stochastic growth model economies which exhibit macroeconomic complementarities and models that emphasize heterogeneity each section of the paper outlines the theory examines relevant empirical evidence and then discusses some policy implications of the analysis

real business cycles under test abstract according to the theory of real business cycles exogenous technological productivity shocks are the primary source of economic fluctuations following the lines of the multisectoral long and plosser 1983 model the paper shows that such a view of business cycles leads to an inherent sectoral ordering in which non consumer sectors are exogenous on the contrary empirical evidence based on var testing and cross spectral methods reveals that consumer goods sectors precede this result can be explained by a simple extension of the dynamic long and plosser innovation process in which significant stochastic demand disturbances are taken into account in particular these demand shocks have to dominate inverse supply innovations such issues of real business cycle theory suggest that only a more explicit modelling of demand influences will reconcile theory with observation

the cyclical behavior of prices abstract the procyclical behavior of prices has been a staple of business cycle lore since the work of the early nber business cycle researchers this paper reexamines that empirical fact the aggregate data do not support procyclical price movements as a stable feature of the business cycle the only episode where it is a robust feature of the data is the period between the two world wars particularly the period of the great depression

endogeneity in brand choice models applications of random utility models to scanner data have been widely presented in marketing for the last 20 years one particular problem with these applications is that they have ignored possible correlations between the independent variables in the deterministic component of utility price promotion etc and the stochastic component or error term in fact marketing mix variables such as price not only affect brand purchasing probabilities but are themselves endogenously set by marketing managers this work tests whether these endogeneity problems are important enough to warrant consideration when estimating random utility models with scanner panel data our results show that not accounting for endogeneity may result in a substantial bias in the parameter estimates

economic fluctuations in central and eastern europe the facts this article provides a detailed empirical analysis of quarterly frequency dynamics in macroeconomic aggregates in 12 countries of central and eastern europe cee it shows that business fluctuations in cee countries are in general more pronounced than in developed ones and are of similar size as in other emerging market economies private consumption is particularly volatile relative to major developed economies government spending is dominantly procyclical and net exports are strongly countercyclical the most frequent country outliers are the high inflation countries of bulgaria romania and russia especially in labour market price and exchange rate variables excluding these countries from the sample makes many of the observed patterns in cyclical dynamics more homogenous and broadly similar to ones established in developed economies

efficiency wages and the business cycle puzzle abstract the main thrust of this work is to open the real business cycle rbc methodology to non walrasian considerations and reciprocally to submit some non walrasian models to the discipline of the rbc approach in doing so we provide a first rbc model with involuntary unemployment and a suboptimal equilibrium path we also demonstrate the promise and difficulty of resolving the business cycle puzzle by appealing to quantity rationing in the labor market

government size and macroeconomic stability abstract we analyze the effects of government size on output variability in the context of a rbc model in which government size is parameterized by the income tax rate and the share of government purchases in output the model implies that i income taxes are destabilizing and ii for most specifications considered government purchases are stabilizing we compare those predictions with the results of simple cross country regressions using data for 22 oecd countries the estimated relationship between empirical indicators of government size and measures of gdp variability appears far stronger than the model predicts and often has the opposite sign

the role of trade and competitiveness measures in us climate policy efforts of the 111th us congress to pass comprehensive climate change legislation although unsuccessful provide insights into the challenges of reaching political agreement on a package for reducing greenhouse gas ghg emissions chief among legislators concerns is the economic burden on their constituents their household energy bills and particularly their jobs perhaps the most vocal interests in the climate debate are the energy intensive manufacturing sectors they argue that the increased costs of carbon pricing will harm their ability to compete in international markets and that trading partners lack of comparable regulation would shift emissions abroad carbon leakage eroding the environmental benefits the salience of those arguments is under scored by statements by senators from industrial states in 2008 ten democratic senators laid out the principles that final legislation should address cost containment relief for working families technology investment equitable treatment of states and prominently enhanced safeguards to ensure a truly equitable and effective global effort that minimizes harm to the us economy and protects american jobs 1

the econometrics of the general equilibrium approach to business cycles early in this century american institutionists and members of the german historical school attacked and rightfully so neoclassical economic theory for not being quantitative this deficiency bothered ragnar frisch and motivated him along with irving fisher joseph schumpeter and others to organize the econometric society in 1930 the aim of the society was to foster the development of quantitative economic theory that is the development of what frisch labeled econometrics soon after its inception the society started the journal econometrica frisch was the journal s first editor and served in this capacity for twenty five years

the rbc models through statistical inference an application with french data the aim of this paper is to evaluate the capacity of rbc models to mimic the french business cycle we are thus led to investigate the three following assumptions on the labour market 1 the non time separability of leisure 2 the indivisibility of labour and 3 the imperfect information on labour market and time varying effort using the general method of moments we estimate the structural parameters and we test 1 the model s hypothesis using a set of overidentifying restrictions and 2 the model s implications i e its ability to reproduce the cyclical features of the french economy

unemployment and the business cycle in a small open economy g m m estimation and testing with french data abstract what is a relevant model for the european business cycle in this paper the empirical performances of three models are compared a canonical walrasian r b c framework its extension to the case of a small open economy and a version of this model with search and wage bargaining on the labor market structural parameters of the models are estimated using g m m and their abilities to reproduce the french business cycle taken as representative of the european business cycle are tested only the small open economy with unemployment is able to generate theoretical moments that match their empirical counterparts

competitive pricing behavior in the auto market a structural analysis in a competitive marketplace the effectiveness of any element of the marketing mix is determined not only by its absolute value but also by its relative value with respect to the competition for example the effectiveness of a price cut in increasing demand is critically related to competitors reaction to the price change managers therefore need to know the nature of competitive interactions among firms in this paper we take a theory driven empirical approach to gain a deeper understanding of the competitive pricing behavior in the u s auto market the ability motivation paradigm posits that a firm needs both the ability and the motivation to succeed in implementing a strategy boulding and staelin 1995 we use arguments from the game theoretic literature to understand firm motivation and abilities in different segments of the auto market we then combine these insights from the game theoretic literature and the ability motivation paradigm to develop hypotheses about competition in different segments of the u s auto market to test our hypotheses of competitive behavior we estimate a structural model that disentangles the competition effect from the demand and cost effects on prices the theory of repeated games predicts that firms with a long run profitability objective will try to sustain cooperative pricing behavior as a stable equilibrium when conditions permit for example markets with high concentration and stable market environments are favorable for sustaining cooperative behavior and therefore provide firms with the ability to cooperate the theory of switching costs suggests that in markets in which a firm s current customers tend to be loyal firms have a motivation to compete very aggressively for new customers recognizing the positive benefits of loyalty from the customer base in the long run as consumer loyalty in the market increases the gains from increasing market share by means of aggressive competitive behavior are more than offset by losses in profit margins firms therefore have the motivation to price cooperatively empirically we find aggressive behavior in the minicom pact and subcompact segments cooperative behavior in the compact and midsize segments and bertrand behavior in the full size segment these findings are consistent with our theory based hypotheses about competition in different segments in estimating a structural model of the auto market we address several methodological issues a particular difficulty is the large number of car models in the u s auto market existing studies have inferred competitive behavior only in markets with two to four products they also use relatively simple functional forms of demand to facilitate easy estimation functional forms of demand however impose structure on cross elasticities between products such structure when inappropriate can bias the estimates of competitive interaction we therefore use the random coefficients logit demand model to allow flexibility in cross elasticities we also use recent advances in new empirical industrial organization neio to extend structural estimation of competitive behavior to markets with a large number of products we use the simulation based estimation approach developed by berry et al 1995 to estimate our model a frequent criticism of the neio approach is that its focus on industry specific studies limits the generalizability of its findings in this study we retain the advantages of neio methods but partially address the issue of generalizability by analyzing competitive behavior in multiple segments within the auto industry to see whether there is a consistent pattern that can be explained by theory theoretical modelers can use our results to judge the appropriateness of their models in predicting competitive outcomes for the markets that they analyze a by product of our analysis is that we also get estimates of demand and cost apart from competitive interactions for the market managers can use these estimates to perform what if analysis they can answer questions about what prices to charge when a new product is introduced or when an existing product s characteristics are changed

international business cycles in theory and in practice this paper investigates whether multi country international business models can account for international comovements in the oecd there are substantial positive comovements between many output components between levels of employment and between total factor productivities the standard international business cycle model is not consistent with these comovements except for consumption levels the model implies either negative or very low comovements this is a robust feature of the theoretical models independently of specific parameter values one interesting finding is that a more general specification of the technology shock processes lead to substantial comovements but at the cost of another deficiency

risk sharing in the business cycle why do all developed economies experience fluctuations in their economic activity the real business cycle rbc literature has provided an answer to this question by demonstrating that a well functioning decentralized model economy subject to exogeneous productivity shocks will behave in a way similar in many respects to the business fluctuations experienced by actual economies kyland and prescott 1982 this is particularly true if one imposes restrictions on the choice set of the representative consumer worker hansen 1985 taking account of demand shocks in the form of variations in government spending further improves the performance of the model christian0 and eichenbaum 1990 should we be content with this answer first we must observe that the set of facts current rbc models are able to replicate is very limited and thus that claims of theoretical success should be proportionately modest danthine and donaldson 1990 second at this level of explanation it is quite likely that the same modest set of facts currently used to define the business cycle will be consistent with models of the economy which are significantly different from the pure walrasian formulations which have predominated to date it is this latter issue tihich we propose to address in this paper our starting point is the observation that all industrial economies have developed institutional and social arrangements designed to improve the distribution of income and risks over what would prevail in walrasian equilibrium trade unions minimum wage laws and unemployment compensation mechanisms are examples of such arrangements and they could be all interpreted as having the objective either of moving the economy away from

current real business cycle theories and aggregate labor market fluctuations hours worked and the return to working are weakly correlated traditionally the ability to account for this fact has been a litmus test for macroeconomic models existing real business cycle models fail this test dramatically we modify prototypical real business cycle models by allowing government consumption shocks to influence labor market dynamics this modification can in principle bring the models into closer conformity with the data our empirical results indicate that it does

aggregate inventory behavior in large european economies abstract inventory fluctuations are known to be an important propagation mechanism for u s business cycles this paper compares the significance of inventory fluctuations in the u s with four other major industrial economies in europe a general model of aggregate inventory demand is specified which seeks to encompass the models presented in recent studies of inventory behavior this model is estimated for the large european economies united kingdom west germany france and italy the preferred models that result from this analysis are compared with the empirical evidence for the u s

european emission trading scheme and competitiveness a case study on the iron and steel industry abstract we quantify the impact of the european emission trading scheme ets on the two dimensions of competitiveness production and profitability for the iron and steel industry among those covered by the scheme this sector is one of the most exposed since it is both highly co 2 intensive and relatively open to international trade we also examine the robustness of these results to various assumptions marginal abatement cost curve trade and demand elasticities as well as pass through rates and updating of allocation rules of which the latter two are scarcely debated we conclude that for this sector competitiveness losses are small we prove this conclusion to be robust hence arguments against tightening the environmental stringency of the ets in phase ii are not justified on grounds of competitiveness loss our systematic sensitivity analysis allows us to identify the important assumptions for each output variable it turns out that pass through rates and updating rules are significant despite being often implicit and least debated in existing analyses

business cycles in switzerland a comparative study abstract the goal of this paper is to provide an empirical description of business cycles in switzerland and a comparison with business cycles in other countries we adopt a view of business cycles as a set of regularities in the movements and the co movements of economic aggregates common to all decentralized economies lucas 1977 and test whether switzerland conforms to this view in order to identify the appropriate cyclical series we follow a procedure proposed by hodrick and prescott 1980 we then compute correlations of various types we test their stability through time and compare with corresponding estimates for the u s france germany and the u k

the persistence of marketing effects on sales are marketing efforts able to affect long term trends in sales or other performance measures answering this question is essential for the creation of marketing strategies that deliver a sustainable competitive advantage this paper introduces persistence modeling to derive long term marketing effectiveness from time series observations on sales and marketing expenditures first we use unit root tests to determine whether sales are stable or evolving trending over time if they are evolving we examine how strong this evolution is univariate persistence and to what extent it can be related to marketing activity multivariate persistence an empirical example on sales and media spending for a chain of home improvement stores reveals that some but not all advertising has strong trend setting effects on sales we argue that traditional modeling approaches would not pick up these effects and therefore seriously underestimate the long term effectiveness of advertising the paper concludes with an agenda for future empirical research on long run marketing effectiveness

international evidence on the historical properties of business cycles we contrast properties of real quantities with those of price levels and stocks of money for ten countries over the last century although the magnitude of output fluctuations has varied across countries and periods relations among real quantities have been remarkably uniform properties of price levels however exhibit striking differences between periods inflation rates are more persistent after world war ii than before and price level fluctuations are typically procyclical before world war ii and countercyclical afterward fluctuations in money are less highly correlated with output in the postwar period but are no more persistent than in earlier periods jel e32 e31

indivisible labor lotteries and equilibrium abstract this paper considers an economy where labor is indivisible and agents are identical although the discontinuity in labor supply at the individual level disappears as a result of aggregation it is shown that indivisible labor has strong consequences for the aggregate bahavior of the economy it is also shown that optimal allocations involve lotteries over employment and consumption

international real business cycles we ask whether a two country real business cycle model can account simultaneously for domestic and international aspects of business cycles with this question in mind we document a number of discrepancies between theory and data the most striking discrepancy concerns the correlations of consumption and output across countries in the data outputs are generally more highly correlated across countries than consumptions in the model we see the opposite

real business cycle theory wisdom or whimsy abstract this paper assesses the empirical plausibility of the view that aggregate productivity stocks account for most of the variability in post world war ii us output we argue that the type of evidence forwarded by proponents of this proposition is too fragile to be believable the answer could be 70 as kydland and prescott 1989 claim but the data contain almost no evidence against either the view that the answer is really 5 or that the answer is really 200 moreover point estimates of the importance of technology shocks are extremely sensitive to small perturbations in the theory depending on the sample period investigated allowing for labor hoarding behavior in an otherwise standard rbc model reduces the ability of technology shocks to account for aggregate fluctuations by between 30 to 60

productivity shocks in a sectoral real business cycle model for west germany abstract if aggregate output is driven by integrated productivity shocks then sectoral output series should display few if any cointegrating relationships similarly serial correlation cofeature should be a rare occurrence these conjectures are confirmed in an analysis with west german data however productivity shocks identified and tested in an extended version of the long and plosser real business cycle model do not contain enough unit roots to account for those found in the output series hence productivity shocks can at best provide a partial explanation for aggregate output fluctuations

measuring market power in the ready to eat cereal industry the ready to eat cereal industry is characterized by high concentration high price cost margins large advertising to sales ratios and numerous introductions of new products previous researchers have concluded that the ready to eat cereal industry is a classic example of an industry with nearly collusive pricing behavior and intense nonprice competition this paper empirically examines this conclusion in particular i estimate price cost margins but more importantly i am able empirically to separate these margins into three sources i that which is due to product differentiation ii that which is due to multi product firm pricing and iii that due to potential price collusion the results suggest that given the demand for different brands of cereal the first two effects explain most of the observed price cost margins i conclude that prices in the industry are consistent with noncollusive pricing behavior despite the high price cost margins leading firms are able to maintain a portfolio of differentiated products and influence the perceived product quality it is these two factors that lead to high price cost margins

the equity premium and the allocation of income risk abstract this paper examines the extent to which the equity premium puzzle can be resolved by taking account of the fact that stockholders bear a disproportionate share of output uncertainty we do this in the context of a non walrasian rbc model where risk reallocation is justified by borrowing restrictions the risk shifting mechanism we propose has the same effect as would arise from an increase in the risk aversion parameter of the representative agent and thus contributes to a rise in the equity premium as with more standard rbc models it remains that our model is unable to replicate key financial statistics in particular the observation that the equity return is more variable than national product cannot be accounted for under standard technology assumptions

a small open economy model with transaction costs in foreign capital abstract in this paper we develop a stochastic dynamic general equilibrium model for a small open economy in the real business cycle modeling tradition household preferences depend on private and public consumption and leisure production technology depends on public capital government finances its investment consumption and transfer payments by means of a proportional income tax rate households buy and sell foreign assets in an international capital market with transaction costs and also receive transfer payments from abroad we calibrate the model for the greek economy the volatility persistence and co movement properties of the business cycle component of the data generated by the model are broadly consistent with the actual behavior of the corresponding actual data we use the model to investigate the response of major macroeconomic variables to temporary and permanent changes in government policy variables foreign transfers and the rate on return of foreign assets we find that increasing government consumption and domestic transfers financed through distorting taxation lowers capital labor in most cases and output while it increases foreign asset holdings both in the short and the long run increasing government investment financed by distorting taxation eventually increases capital and output and decreases labor finally transfers from abroad decrease capital labor and output while they increase consumption

tax analysis in a real business cycle model on measuring harberger triangles and okun gaps abstract a tax distorted real business cycle model is parameterized calibrated and solved numerically in an attempt to measure the size of harberger triangles relative to okun gaps in particular the model constructed is used to study quantitatively the impact of various distortional government tax and subsidy schemes it is shown that the government can use tax policy to stabilize cyclical fluctuations and this is done for the economy being studied the benefits of implementing such a stabilization policy are calculated and compared with the size of the welfare gains realized from reducing various tax distortions

advertising effects in presidential elections presidential elections provide both an important context in which to study advertising and a setting that mitigates the challenges of dynamics and endogeneity we use the 2000 and 2004 general elections to analyze the effect of market level advertising on county level vote shares the results indicate significant positive effects of advertising exposures both instrumental variables and fixed effects alter the ad coefficient advertising elasticities are smaller than are typical for branded goods yet significant enough to shift election outcomes for example if advertising were set to zero and all other factors held constant three states electoral votes would have changed parties in 2000 given the narrow margin of victory in 2000 this shift would have resulted in a different president

net exports consumption volatility and international business cycle models abstract conventional two country rbc models interpret countercyclical net exports as reflecting primarily the dynamics of capital i show that quantitatively theoretical economies rely on counterfactual terms of trade effects trade fluctuations on the contrary are driven by consumption smoothing thus generating procyclical net trade in goods i then consider a class of preferences that embeds home production in a reduced form consumption volatility increases so that countercyclical net exports reflect primarily a strong relation between consumption and imports as in the data the major discrepancy between theory and data concerns the variability of international prices

participation in gvcs and co2 emissions abstract this paper attempts to explore the determinants of co2 emissions in the context of international trade while there exist studies that examine the roles of horizontal specialization and inter industry trade transactions little previous research attention has been paid to the roles of vertical specialization and intra industry trade transactions in affecting co2 emissions to fill the knowledge gap this study uses the panel data of 62 countries and regions for the period of 1995 2011 to estimate the effect of participation in global value chains gvcs on per capita co2 emissions major findings include 1 the relationship between participation degrees in gvcs and per capita co2 emissions is found to be inversely u shaped at the aggregate economy level and for most individual industries 2 per capita gdp shows an n shaped relationship with per capita co2 emissions and 3 benign drivers of co2 emissions include r d energy conservation and population control it can be concluded that countries with low gdp or gvc participation degrees are expected to experience worsening co2 emissions in the short or even medium run this trend however can be moderated or even reversed with more r d investments

asset returns with transactions costs and uninsured individual risk abstract we explore whether incorporating an explicit motive for holding liquid assets within an equilibrium asset pricing model helps explain the following features of asset returns and turnover in the post war u s economy i the low risk free real interest rate ii the large spread between returns on liquid assets and stocks and iii the greater transaction velocity of liquid assets relative to stocks we introduce a demand for liquid assets by adding uninsured individual risk together with differential costs of trading securities numerical simulations attempting to match the return data generate a ratio of liquid assets to income considerably below observed levels

dynamics of the trade balance and the terms of trade the j curve the authors provide a theoretical interpretation of two features of international data the countercyclical movements in net exports and the tendency for the trade balance to be negatively correlated with current and future movements in terms of trade but positively correlated with past movements they document the same properties in a two country stochastic growth model in which trade fluctuations reflect in large part the dynamics of capital formation the authors find that their general equilibrium perspective is essential the relation between the trade balance and the terms of trade depends critically on the source of fluctuations copyright 1994 by american economic association

carbon motivated border tax adjustments old wine in green bottles 1285 ben lockwood and john whalley we discuss emerging proposals for border tax adjustments btas to accompany commitments to reduce carbon emissions in the eu the us and other oecd economies the rationale offered for such border adjustment is that various entities such as the eu if making commitments to reduce emissions which go beyond those undertaken in other regions of the world impose added costs on domestic producers which create a competitive disadvantage for them some form of remedy is viewed as reasonable to maintain the competitiveness of domestic industries when responding to global environmental problems in this paper we argue that despite its current carbon manifestation the issue of border tax adjustments and both their rationale and their effects on trade are not new and despite the present debate which seems to overlook older literature have arisen before earlier debate on border tax adjustments occurred at the time of the adoption of the value added tax vat in the eu as a tax harmonisation target in the early 1960s but academic literature of the time showed that a change between origin and destination basis in the vat would be neutral and hence the use of a destination based tax in the eu to accompany the vat offered no trade advantage to europe here we argue that essentially the same arguments also apply for carbon motivated btas and in the current debate there seems to be a misconception between price level effects and relative price effects stemming from a bta which needs correcting we also argue that the impact of border tax adjustments should be viewed as independent of the motivation of the adjustments

the output employment and interest rate effects of government consumption abstract we study the impact on aggregate variables of changes in government consumption using the neoclassical stochastic growth model we show theoretically that the impact on output and employment of a persistent change in government consumption exceeds that of a temporary change we also show that in principle there can be an analog to the keynesian multiplier in the neoclassical growth model finally in an empirically plausible version of the model we show that the interest rate impact of a persistent government consumption shock exceeds that of a temporary one our results provide counterexamples to existing claims in the literature

comparisons of business cycles in the ec idiosyncracies and regularities annual data since 1960 and the real business cycle model as a guidance the evidence suggests that there are remarkable similarities between the business cycle pattern of these countries despite significant differences in the patterns of fiscal and monetary policies and the terms of trade we take this evidence to suggest that the type of shocks and the propagation mechanism is fairly similar across the ec countries hence the process of european integration under a set of uniform institutions and policies should not be a problem as far as the business cycle is concerned

realistic cross country consumption correlations in a two country equilibrium business cycle model abstract a well known feature of one good multi agent arrow debreu economies with edentical additively separable homothetic preferences is that the consumptions of all agents are perfectly correlated such economies are widely used in interpreting business cycles but seem to be inconsistent with observed cross country correlations of aggregate consumption this paper provides an example of a two country real business cycle model in which preferences are not separable between consumption and labor supply the model has a simple closed form solution closed form solution and allows for fluctuations in labor supply in equilibrium moreover it generates correlations between national consumption rates which are close to some of those observed in historical data jel f41

production growth and business cycles ii new directions abstract this paper outlines new directions for investigations of real business cycle models consideration of stochastic growth of exogenous and endogenous forms analysis of suboptimal outcomes arising due to externalities of distorting taxes and implications of labor market heterogeneity

between a rock and a hard place a trade theory analysis of leakage under production and consumption based policies without a comprehensive global climate agreement carbon leakage remains a contentious issue consumption based pricing of emissions which could in practice be implemented with a full border tax adjustment bta has been forwarded as an option to increase the effectiveness of unilateral climate policy this paper questions the economic rationale behind this approach using a theoretical 2 times 2 trade model in which leakage occurs through terms of trade effects we show analytically first that consumption based pricing of emissions does not necessarily result in less leakage than production based policies second the sign of the optimal unilateral carbon tariff depends on the carbon intensity differential between the foreign country s exporting and non exporting sectors and not on the differential between home s and foreign s exporting sectors as implied by the full bta approach third based on empirical data for the year 2004 our model implies that full bta applied by the european union on e g imports from and exports to china would by shifting china s production from the export sector with a relatively low carbon intensity towards the more carbon intensive non export sector actually increase leakage

output based allocation of emissions permits for mitigating tax and trade interactions the allocation of tradable emissions permits has important efficiency as well as distributional effects when tax and trade distortions are taken into account we compare different rules for allocating carbon allowances within sectors lumpsum grandfathering output based allocation oba auctioning and among sectors historical emissions or value added shares the output subsidies implicit in oba mitigate tax interactions unlike grand fathering oba with sectoral distributions based on value added is similar to revenue recycling with auctioning oba based on historical emissions supports heavier polluters more effectively counter acting carbon leakage but at higher welfare costs less energy intensive sectors are also sensitive to allocation rules

methodological and empirical issues in real business cycle theory abstract in this paper we argue that the major impact of the rbc literature has been to propose a new methodology for macroeconomics this methodology is distinguished first by the importance it attributes to the empirical description of the phenomena to be explained and second by the use of this description in conjunction with quantitative theorizing i e the construction of computable general equilibrium models whose characteristic statistics match those of the data in accordance with this approach we first report on the current state of knowledge concerning business cycle regularities and conclude that additional empirical effort is called for in order to arrive at the appropriate basis for theorizing we then examine the performance of existing models and evaluate the case for integrating monetary factors and demand shocks into them lastly we review the recent efforts to explain the employment variability puzzle and argue that the search for a solution naturally leads to the incorporation of significant non walrasian features into the rbc framework

climate change policy market structure and carbon leakage abstract the 1997 kyoto protocol on climate change obliges the industrialized countries to initiate the international effort of abating anthropogenic greenhouse gas ghg emissions if such an initiative is to be taken the associated competitive effects may lead to significant relocation of developed countries energy intensive production this paper examines this issue i adopt an oligopolistic structure combined with increasing returns to scale production technologies to represent the strategic interaction among the firms producing energy intensive products this representation is then embedded within a multi regional computable general equilibrium model which in turn is used for quantifying these relocational effects the results suggest that significant relocation of energy intensive industries away from the oecd may occur depending on the type of market structure with leakage rates as high as 130 in which case ghg control policies in the industrialized countries actually lead to higher global emissions

labour market institutions liquidity constraints and macroeconomic stability abstract the sensitivity of employment and real wages hence aggregate labour income to short run fluctuations in output varies across countries we develop a simple theoretical model to show that if workers but not capitalists are liquidity constrained the sensitivity of an economy to exogenous expenditure shocks is inversely related to the extent to which capitalists rather than workers bear fluctuations in income we perform an econometric test of this proposition using cross sectional country level data the empirical results support the view that the lower the sensitivity of labour income to output fluctuations the smaller the output fluctuations themselves will be

real business cycles a new keynesian perspective the debate over the source and propagation of economic fluctuations rages as fiercely today as it did 50 years ago in the aftermath of keynes s the general theory and in the midst of the great depression today as then there are two schools of thought the classical school emphasizes the optimization of private economic actors the adjustment of relative prices to equate supply and demand and the efficiency of unfettered markets the keynesian school believes that understanding economic fluctuations requires not just studying the intricacies of general equilibrium but also appreciating the possibility of market failure on a grand scale

business cycles under monetary union a comparison of the eu and us reserve districts in the usa and the 15 countries that make up the eu the comparison is suggestive of what might be expected to emerge in the way of business cycle synchronization from a monetary union between the member states of the eu now simply non decimal denominations of the euro and the national central banks of the 11 are branches of the european system of central banks many prominent observers doubted that europe would ever reach this stage and many continue to believe that monetary union between such a large and dispar ate group of countries is fundamentally unsound a key element in the argu ments of many critics of emu is the degree of business cycle asynchronicity between the member states of the eu this paper contributes to the ongoing debate by documenting key differences and similarities between business cycles in the eu and business cycles in the 12 federal reserve districts in the united states the practice of looking to the us experience for insights into the problems and functioning of a monetary union has a long precedent in the literature on fixed exchange rates in general and in the literature on emu in particular for example in making an argument for fixed exchange rates rolnick and weber 1994 note that the usa can be viewed as having a system of fixed exchange rates between currencies issued by the 12 regional federal reserve banks they argue that the notes issued by the 12 banks are not strictly ident ical and that the difference between the notes creates the possibility that the united states could have a system of floating exchange rates among the 12 federal reserve districts 1 rolnick and weber go on to examine the features of the relationship among the 12 regional federal reserve banks that make a system of fixed exchange rates between them feasible in the process drawing lessons for how a monetary union among the countries of the eu might work the analysis in this paper complements earlier analyses in a number of ways the resurgence of interest in business cycle research over the past 20

comparing policies to combat emissions leakage border carbon adjustments versus rebates we explore conditions determining which anti leakage policies might be more effective complements to domestic greenhouse gas emissions regulation we consider four policies that could be combined with unilateral emissions pricing to counter effects on international competitiveness a border charge on imports a border rebate for exports full border adjustment and domestic output based rebating each option faces different potential legal hurdles in international trade law each also has different economic impacts while all can support competitiveness none is necessarily effective at reducing global emissions nor is it possible to rank order the options effectiveness depends on the relative emissions rates elasticities of substitution and consumption volumes we illustrate these results with simulations for the energy intensive sectors of three different economies the united states canada and europe although most controversial full border adjustment is usually most effective but output based rebating for key manufacturing sectors can achieve many of the gains

does growth vary over the business cycle some evidence from the g7 countries in this paper we analyse the dynamics of business cycles in the g7 countries our aim is to answer the question of whether growth varies in an absolute sense over the business cycle and hence to examine whether the simple two phase characterization downturn upturn is an appropriate description of the business cycle to study growth over the cycle we estimate single country equations and then a pooled regression that takes into account the important interactions of international business cycles the results confirm the steepness asymmetry of the growth cycles and show that growth varies systematically within upturns and downturns these are consistent with the notion of deepness asymmetry which implies that contractions are more pronounced in the later stages of a downturn whereas expansions are stronger immediately after troughs

environmental taxes and international spillovers the case of a small open economy abstract in the existence of trade interaction a sub global climate change policy can generate externality which can cause competitiveness issues for the producers in compliant regimes however among compliant regions a small economy also receives a significant spillins effect when a large economy takes some regulatory actions that affect particularly the world prices of traded commodities this externality can have notable impacts on the efficiency and pollution abatement opportunities of the small compliant regime with a trivial converse effect in some cases these impacts on the efficiency and emissions abatement can be in opposite directions we capture these findings by incorporating two protection polices i e border tax adjustment and free emissions allocations to emission intensive and trade exposed industries in a multi region analytical and numerical general equilibrium modeling framework these results convey that the large economies hold leading strategic positions towards a cooperative global climate change movement because of their policies influences on the small economies

the dynamic advertising effect of collegiate athletics i measure the spillover effect of intercollegiate athletics on the quantity and quality of applicants to institutions of higher education in the united states an effect popularly known as the flutie effect i treat athletic success as a stock of goodwill that decays over time similar to that of advertising a major challenge is that privacy laws prevent us from observing information about the applicant pool i overcome this challenge by using order statistic distribution to infer applicant quality from information on enrolled students using a flexible random coefficients aggregate discrete choice model that accommodates heterogeneity in preferences for school quality and athletic success as well as an extensive set of school fixed effects to control for unobserved quality in athletics and academics i estimate the impact of athletic success on applicant quality and quantity overall athletic success has a significant long term goodwill effect on future applications and quality however students with lower than average sat scores tend to have a stronger preference for athletic success whereas students with higher sat scores have a greater preference for academic quality furthermore the decay rate of athletics goodwill is significant only for students with lower sat scores suggesting that the goodwill created by intercollegiate athletics resides more extensively with lower scoring students than with their higher scoring counterparts but surprisingly athletic success impacts applications even among academically stronger students

cost of business cycles with indivisibilities and liquidity constraints it is almost universally agreed that individuals face incomplete insurance markets and cannot perfectly insure against the idiosyncratic risk in this paper simple general equilibrium models with incomplete insurance markets are examined in order to assess the impact of imperfect insurance on the magnitude of the welfare costs of business cycles two versions of incomplete insurance markets are considered and certain statistical properties of the equilibrium stochastic processes in these environments are compared with those of a perfect insurance economy

the structure of the climate debate first best climate policy is a uniform carbon tax which gradually rises over time civil servants have complicated climate policy to expand bureaucracies politicians to create rents environmentalists have exaggerated climate change to gain influence other activists have joined the climate bandwagon opponents to climate policy have attacked the weaknesses in climate research the climate debate is convoluted and polarized as a result and climate policy complex climate policy should become easier and more rational as the paris agreement has shifted climate policy back towards national governments changing political priorities austerity and a maturing bureaucracy should lead to a more constructive climate debate

a cross country comparison of the cyclicality of real wages this paper contains the first cross country comparison of the cyclical behaviour of real wages using microdata after controlling for changes in labour quality i find that real wages are strongly procyclical in canada the united kingdom and the united states in contrast the cyclicality of government published real aggregate hourly wages varies substantially across these three countries the disparity suggests that a direct comparison of the cyclical behaviour of real aggregate wages is misleading finally i show that variations in labour quality also bias the cross country correlation of several key labour market variables jel classification j3 e3 une comparaison transversale entre pays du caractere cyclique des salaires reels ce memoire presente la premiere comparaison entre pays du comportement cyclique des salaires reels a l aide de micro donnees apres normalisation pour tenir compte des changements dans la qualite du travail cette etude montre que les salaires reels sont pro cycliques au canada au royaume uni et aux etats unis au contraire le caractere cyclique des donnees sur les salaires horaires agreges varie substantiellement entre ces trois pays cette disparite suggere qu une comparaison directe du comportement cyclique des salaires reels agreges peut etre trompeuse finalement cette etude montre que les variations dans la qualite du travail biaisent aussi les correlations entre pays de plusieurs variables du marche du travail

stochastic fiscal policy and the swedish business cycle in this paper we show that fluctuations in distortive taxes can account for some of the key features of the swedish post war business cycle the empirical fit of a simple stochastic growth model is significantly improved when it is amended to include imperfectly predictable fluctuations in payroll taxes consumption taxes and government consumption indeed using the simulated method of moments smm we find that for large sets of conventional moments models with stochastic fiscal policy cannot be statistically rejected whereas a model without it is always rejected

robust policies to mitigate carbon leakage abstract unilateral climate policy induces carbon leakage through the relocation of emission intensive and trade exposed industries to regions without emission regulation previous studies suggest that emission pricing combined with border carbon adjustment is a second best instrument and more cost effective than output based rebating we show that the combination of output based rebating and a consumption tax for emission intensive and trade exposed goods can be equivalent with border carbon adjustment moreover it is welfare improving for a region that implements emission pricing along with output based rebating to introduce such a consumption tax the welfare gain is particularly large if output based rebating is already implemented for a sector that is not much exposed to leakage e g due to uncertainty about exposure or due to lobbying activities thus supplementing output based rebating with a consumption tax constitutes robust policies to mitigate carbon leakage

understanding real business cycles he 1 960s were a time of great optimism for macroeconomists many economists viewed the business cycle as dead the keynesian model was the reigning paradigm and it provided all the necessary instructions for manipulating the levers of monetary and fiscal policy to control aggregate demand inflation occurred if aggregate demand was stimulated excessively and unemployment arose if demand was insufficient the only dilemma faced by policymakers was determining the most desirable location along this inflation unemployment tradeoff or phillips curve the remaining intellectual challenge was to establish coherent microeconomic foundations for the aggregate behavioral relations posited by the keynesian framework but this was broadly regarded as a detail that should not deter policymakers in their efforts to stabilize the economy the return of the business cycle in the 1970s after almost a decade of economic expansion and the accompanying high rates of inflation came as a rude awakening for many economists it became increasingly apparent that the basic keynesian framework was not the appropriate vehicle for understanding what happens during a business cycle nor did it seem capable of providing the empirically correct answers to questions involving changes in the economic environment or changes in monetary or fiscal policy the view that keynesian economics was an empirical success even if it lacked sound theoretical foundations could no longer be taken seriously the essential flaw in the keynesian interpretation of macroeconomic phenomenon was the absence of a consistent foundation based on the choice theoretic framework of microeconomics two important papers one by milton friedman 1968 and the other by robert lucas 1976 forcefully demonstrated examples of

real business cycles in this paper we demonstrate how certain very ordinary economic principles lead maximizing individuals to choose consumption production plans that display many of the characteristics commonly associated with business cycles our explanation is entirely consistent with i rational expectations ii complete current information iii stable preferences iv no technological change v no long lived commodities vi no frictions or adjustment costs vii no government viii no money and ix no serial dependence in the stochastic elements of the environment we also provide a completely worked out example of the type of artificial economy we have in mind the time series properties of the example exhibit some major features of observed business cycles although this type of model may not be capable of explaining all of the regularities in actual business cycles we believe that it provides a useful well defined benchmark for assessing the relative importance of factors e g monetary disturbances
