budget processes and commitment to fiscal discipline abstract we present a framework of investigation into the political economy of the budget process our model suggests that institutional rules governing the budget process can be found to limit the importance of fiscal illusion empirical evidence supports that proposition the choice of rules depends on the political environment as well as the dominant source of uncertainty in the budget process

are the determinants of co2 emissions converging among oecd countries this paper studies convergence in co2emission intensity co2 emissions over gdp among oecd countries over the period 1960 2008 based on its determinants namely energy intensity energy consumption over gdp and the so called carbonisation index co2 emissions over energy consumption we apply the phillips and sul 2007 methodology which tests for the existence of convergence clubs our results highlight that differences in emission intensity convergence are more determined by differences in convergence of the carbonisation index rather than by differences in the dynamic convergence of energy intensity

politics and efficiency of separating capital and ordinary government budgets we analyze a golden rule that separates capital and ordinary account budgets and allows a government to finance only capital items with debt many national governments followed this rule in the eighteenth and nineteenth centuries and most u s states do today we study an overlapping generations economy where majorities choose durable and nondurable public goods in each period when demographics imply even moderate departures from ricardian equivalence the golden rule substantially improves efficiency examples calibrated to u s demographics show greater improvements at the state level or with nineteenth century demographics than under current national demographics

why has u s inflation become harder to forecast we examine whether the u s rate of price inflation has become harder to forecast and to the extent that it has what changes in the inflation process have made it so the main finding is that the univariate inflation process is well described by an unobserved component trend cycle model with stochastic volatility or equivalently an integrated moving average process with time varying parameters this model explains a variety of recent univariate inflation forecasting puzzles and begins to explain some multivariate inflation forecasting puzzles as well

boom bust cycle asymmetrical fiscal response and the dutch disease this paper investigates the changes in expenditure policy in oil exporting countries during boom bust in commodity price cycles and their implications for real exchange rate movements to do so we introduce a dutch disease model with downward rigidities in government spending to revenue shocks this model leads to a decoupling between real exchange rate and commodity export price movement during busts we test our model s theoretical predictions and underlying assumptions using panel data for 32 oil exporting countries over the period 1992 to 2009 results are threefold first we find that changes in current spending have a stronger impact on real exchange rate compared to capital spending second we find that current spending is downwardly sticky but increases in boom time and conversely for capital spending third we find limited evidence that fiscal rules have helped reduce the degree of responsiveness of current spending during booms in contrast we find evidence that fiscal rules are associated with a significant reduction in capital expenditure during busts while responsiveness to booms is more muted this raises concerns on potential adverse consequences of this asymmetry on economic performance in oil exporting countries

is trade good or bad for the environment sorting out the causality we seek to contribute to the debate over globalization and the environment by asking what is the effect of trade on a country s environment for a given level of gdp we take specific account of the endogeneity of trade using exogenous geographic determinants of trade as instrumental variables we find that trade tends to reduce three measures of air pollution statistical significance is high for concentrations of so2 moderate for no2 and lacking for particulate matter although results for other environmental measures are not as encouraging there is little evidence that trade has a detrimental effect on the environment

are shocks to ecological footprint in oecd countries permanent or temporary abstract the main goal of this study is to check the unit root properties of the ecological footprint and its six subcomponents cropland footprint grazing land footprint fishing grounds footprint forest land footprint built up land footprint and carbon footprint in 25 oecd the organisation for economic co operation and development countries during the period 1961 2013 this study uses a new stationarity test with sharp and smooth breaks in the panel setting developed by bahmani oskooee et al 2014 empirical findings demonstrate that the fishing grounds footprint does not have mean reverting behavior while the remaining ecological indicators display stationary properties under the assumption of both homogenous and heterogeneous long run variance therefore if policymakers decide to decrease the size of the fishing grounds footprint they will not face stiff resistance in addition to the panel results the univariate stationarity test results can also help policymakers in each country design effective emission reduction policies

competition and cooperation in the market for exclusionary rights salop and david scheffman 1983 show that firms profitably can gain market power by conduct that raises their competitors costs raising rivals costs is a more credible route to market power than is predatory pricing because it is not necessary to cause the rivals to exit no deep pocket is required and the additional profits are gained immediately that paper argues that vertical restraints and contracts with input suppliers can be fertile ground for raising competitors costs by contracting with one or more suppliers to exclude rivals either by dealing with them on discriminatory terms or refusing to deal with them altogether a firm sometimes can increase its rivals costs as a result it can sometimes gain the power to raise price in the market in which it sells output this type of contract often can be characterized as the purchase of an exclusionary right from the input suppliers that is in addition to the purchase of inputs the predator also purchases the right to exclude some of its rivals from access to the suppliers inputs exclusionary rights contracts can exist in a variety of forms at one extreme are agreements that involve only exclusionary rights no inputs are exchanged at all for example it was reported in alcoa that at one time alcoa purchased exclusionary covenants from power companies from which it did not purchase electricity the contracts involved only the utilities promises not to sell electricity to other aluminum companies such naked exclusionary rights contracts are unusual of course most exclusionary rights are bundled with the sale of inputs for example stroh beer has alleged that the two major brewers purchase not only advertising time on network sports programs but also the right to exclude remaining brewers from advertising on those same programs even though the networks have other advertising time available it might be argued that such exclusionary conduct would always fail for two reasons the excluded rivals would have available effective counterstrategies to prevent their own exclusion and input suppliers would have no incentives to reduce their sales by excluding some customers these criticisms imply that raising rivals costs by contracting with suppliers would not be credible it surely is not true that exclusionary strategies to restrict rivals input purchases will always succeed in raising their costs for example where rivals easily can substitute to other equally cost effective inputs or where entry into the production of inputs is so easy that the excluded rivals can efficiently produce the input themselves then cost raising strategies will fail moreover where competition in the output market would be sufficient to maintain low prices despite the exit or increased costs of the excluded competitors then no profit maximizing firm would spend any resources trying to exclude those rivals these conditions are discussed in detail in our earlier paper 1985 tdiscussants ronald h coase university of chicago gregory k down yale university david sappington bell communications research and university of pennsylvania

club convergence in carbon dioxide emissions we examine convergence in carbon dioxide emissions among 128 countries for the period 1960 2003 by means of a new methodology introduced by phillips and sul econometrica 75 6 1771 1855 2007a contrary to previous studies our approach allows us to examine for evidence of club convergence i e identify groups of countries that converge to different equilibria our results suggest convergence in per capita co2 emissions among all the countries under scrutiny in the early years of our sample however there seem to be two separate convergence clubs in the recent era that converge to different steady states interestingly we also find evidence of transitioning between the two convergence clubs suggesting either a slow convergence between the two clubs or a tendency for some countries to move from one convergence club to the other

testing for convergence in carbon dioxide emissions using a century of panel data this paper tests the convergence in per capita carbon dioxide emissions for a collection of developed and developing countries using data spanning the period 1870 2002 for this purpose three recently developed panel unit root tests that permit for dependence among the individual countries are employed the results lend strong support in favor of convergence for the panel as a whole estimates of the speed of this convergence is also provided

convergence of per capita co2 emissions across the globe insights via wavelet analysis abstract this paper examines the convergence of per capita carbon dioxide co2 emissions for 162 countries across the globe covering all income groups high income oecd high income non oecd middle income and low income countries as categorized by the world bank the incidence of stochastic convergence is analysed by making use of recently developed wavelet based unit root tests the existing studies on this subject make use of conventional unit root tests using time series and or panel data a serious drawback of these tests is that they analyse the stochastic behaviour of any series in time domain only whereas the stochastic process may behave differently across different frequencies as well thus wavelet methods are an obvious solution as they consider frequency dimension as well in addition to time dimension when analyzing the stochastic behaviour of any data series and hence these methods encompass the conventional unit root testing methodologies by providing a clear and complete picture of the stochastic process our empirical findings based on latest available time series annual data from 1960 to 2010 lend support in favor of convergence among 38 countries including 18 high income oecd countries 2 high income non oecd countries 13 middle income countries and 5 low income countries while for the rest of 124 countries the co2 emission series is found to be non stationary suggesting the divergence in these countries these findings are in contrast with the most of the existing studies which may be due to the use of wavelet based unit root tests that are of course better alternatives some policy implications evolve from the empirical findings

profiting from countervailing power an effect of government control we demonstrate that a firm subject to government regulation might expect an increase in profit upon creation of an independent monopoly upstream such a monopoly serves to increase the expected cost of the regulated firm as a result even regulators who behave socially optimally will decrease the frequency with which they audit reports of high production cost the reduction in governmental investigation permits the firm to increase the rents it derives from its superior information about cost the possible implications of our model for a theory of political limit pricing are also briefly mentioned

convergence in carbon dioxide emissions among industrialised countries revisited this paper examines the existence of stochastic and deterministic convergence of carbon dioxide co2 emissions in 23 countries over the period 1960 2002 for that purpose we conduct unit root testing by employing the recently developed panel stationarity test of carrion i silvestre et al carrion i silvestre j l del barrio castro t lopez bazo e 2005 breaking the panels an application to the gdp per capita econometrics journal 8 159 175 which assumes a highly flexible trend function by incorporating an unknown number of structural breaks we accommodate general forms of cross sectional dependence as well as control for finite sample bias through bootstrap methods overall our analysis provides strong evidence supporting both stochastic and deterministic convergence in co2 emissions thus confirming strazicich and list strazicich m c list j a 2003 are co2 emission levels converging among industrial countries environmental and resource economics 24 263 271 and westerlund and basher westerlund j basher s a 2007 testing for convergence in carbon dioxide emissions using a century of panel data environmental and resource economics forthcoming findings of convergence

growth friendly fiscal rules safeguarding public investment from budget cuts through fiscal rule design abstract we study patterns of public investment behavior during fiscal consolidations in seventy five advanced and emerging economies during 1990 2018 and find that results differ significantly depending on fiscal rule design fiscal rules can be flexible meaning that they include mechanisms to accommodate exogenous shocks e g cyclically adjusted fiscal targets well defined escape clauses and differential treatment of investment expenditures or rigid meaning they establish numerical limits on fiscal targets without taking into account flexible features we find that in countries with either no fiscal rule or with a rigid fiscal rule a fiscal consolidation of at least 2 percent of gdp is associated with an average 10 percent reduction in public investment instead in countries with flexible fiscal rules the negative effect of fiscal adjustments on public investment vanishes which implies that flexible rules protect public investment during consolidation episodes the corollary is that the design of fiscal rules can add a growth friendliness dimension to the fiscal sustainability objective that has typically been the focus of fiscal rules in the past provided public investment is productive

convergence of per capita carbon dioxide emissions in the eu legend or reality abstract designing appropriate environmental and energy policies in order to meet the kyoto protocol s carbon dioxide co 2 reduction targets in the european union eu requires a detailed examination and thorough understanding of co 2 emission trends across the eu member states this paper investigates whether co 2 emissions have converged across 22 european countries over the 1971 to 2006 period the bayesian shrinkage estimation method is employed to do this work and the results reveal the following first the hypothesis of absolute convergence in per capita co 2 emissions is supported and a slight upward convergence is observed second the fact that countries differ considerably in both their speed of convergence and volatility in emissions makes it possible to identify different groups of countries third the results with respect to convergence do not vary much once the share of industry in gdp is accounted for in a conditional convergence analysis however a decreasing share of industry in gdp seems to contribute to a decline in per capita emissions these findings may carry important implications for both national and eu environmental policies

good bad or ugly on the effects of fiscal rules with creative accounting abstract do fiscal rules lead to fiscal adjustment or do they encourage the use of creative accounting this question is studied with a model in which fiscal rules are imposed on measured fiscal variables which can differ from true variables because there is a margin for creative accounting the probability of detecting creative accounting depends on its size and the transparency of the budget the model studies the effects on fiscal policy of a budget rule separating structural from cyclical effects and examines how these effects depend on the underlying fiscal distortion and on the degree of transparency of the budget

production and consumption based convergence analyses of global co2 emissions abstract the convergent trend of co2 emissions has received wide spread attention in an attempt to meet the global reduction target but almost all of the focus has been on the production side a systematic investigation on the convergence of global co2 emissions from the production side and the consumption side is of great importance to find the pathways for the worldwide low carbon development this study distinguished production and consumption based co2 emissions of 129 economies during the period 1995 2015 based on traditional sigma gamma beta stochastic and club convergence models we identified convergence progress of co2 emission on both the production and consumption sides taking convergence speed and influential factors into account we demonstrated different convergence pathways to a reasonable climate strategy this study obtained four key results first in all cases global per capita co2 emissions on the production and consumption sides were convergent second the speed of convergence on the production side was higher than on the consumption side third population density energy intensity and the share of trade and industrialization had significant effects on the production side while per capita gdp was more important on the consumption side low carbon development due to medium and high technology manufacturing had equal impacts on consumption and production forth different convergence processes among organization for economic co operation and development oecd european union eu asia pacific economic cooperation apec and rest80 i e the other 80 developing economies indicate that mitigation policies should differ according to the industrial structure and by economic development the results of this study will extend our empirical understanding of global co2 emissions and their policy implications

why is fiscal policy often procyclical many countries especially developing ones follow procyclical fiscal policies namely spending goes up taxes go down in booms and spending goes down taxes go up in recessions we provide an explanation for this suboptimal fiscal policy based upon political distortions and incentives for less than benevolent government to appropriate rents voters have incentives similar to the starving the leviathan classic argument and demand more public goods or fewer taxes to prevent governments from appropriating rents when the economy is doing well we test this argument against more traditional explanations based purely on borrowing constraints with a reasonable amount of success

voting on the budget deficit comment textabstractin this comment it is argued that a balanced budget rule may cause underinvestment as a consequence such a rule is not ex ante efficient in order to achieve the ex ante optimal outcome it would be necessary to add an extra rule for the level of public investment unfortunately however such an investment rule is likely to be very difficult to implement in practice when there are no rules to prevent underinvestment it is no longer clear whether a balanced budget rule is beneficial or not in some cases the cost of low levels of investment outweigh the benefits of a balanced budget

have air pollutant emissions converged among u s regions evidence from unit root tests previous studies of income distribution have found evidence indicating that incomes across u s regions have converged supporting the prediction of the neoclassical growth model a potential shortcoming in these studies is that only one measure of well being is considered a measure of wealth linked to incomes or production this paper examines whether income convergence was accompanied by air pollutant emission convergence results from unit root tests provide some evidence that indicators of environmental quality have converged across u s regions during the 1929 1994 period

behavior of the firm under regulatory constraint a recent article by akira takayama discusses an earlier paper by harvey averch and leland l johnson on fair rate of return regulation of public utilities although takayama p 255 agrees with averch and johnson s general conclusions that a firm will tend to increase its investment with the introduction of an active constraint on its rate of return he criticizes the a j argument as being confusing ambiguous and in error takayama then attempts a clarification and presents a new formulation which leads to the a j result quoted above this comment will discuss several of takayama s criticisms in addition to showing that the so called a j effect cannot be derived from the basic assumptions made by both averch and johnson and takayama 1 we will show that the very assumptions used to prove the a j effect by defining the region of x require an assumption that the a j effect exists in the first place

the macroeconomic effects of fiscal rules in the us states abstract fiscal policy restrictions are often criticized for limiting the ability of governments to react to business cycle fluctuations and consequently the adoption of quantitative restrictions is viewed as inevitably leading to increased macroeconomic volatility in this paper we use data from 48 us states to investigate how budget rules affect fiscal policy outcomes our key findings are that 1 strict budgetary restrictions lead to lower policy volatility i e less aggressive use of discretion in conducting fiscal policy and 2 fiscal restrictions reduce the responsiveness of fiscal policy to output shocks these two results should have opposite effects on output volatility while less discretion should reduce volatility less responsiveness of fiscal policy might amplify business cycles we provide empirical support for the first effect restrictions by reducing discretion in fiscal policy can reduce macroeconomic volatility

macroeconomic effects of fiscal adjustment a tale of two approaches abstract we investigate the short term effects of fiscal adjustment on economic activity in 20 oecd countries from 1970 to 2009 we compare two approaches the traditional approach based on changes in cyclically adjusted primary balance capb and the narrative approach based on historical records proponents of the latter argue that it captures discretionary fiscal adjustment more accurately than the traditional approach we propose a new definition of capb that takes account of fluctuations in asset prices and reflects idiosyncratic features of fiscal policy in individual countries using this new definition we find that fiscal adjustments always have contractionary effects on economic activity in the short term we find no evidence of expansionary non keynesian fiscal adjustments spending based fiscal adjustments lead to smaller output losses than tax based fiscal adjustment these results are in line with the literature using the narrative approach suggesting that the capb when correctly specified can be used as a measure of fiscal adjustments

regulation asymmetric information and auditing this article analyzes a model of a regulated firm that is better informed about its cost function than is the regulator by auditing at a cost however the regulator is assumed to be able to observe the realized cost of the firm if the regulator finds that the firm had misrepresented its costs at the time at which prices were set he can order a refund to consumers in the optimal policy the regulator audits when the firm reports for pricing purposes that its costs will be high and orders a refund when the auditfinds that realized costs are lower than anticipated given the original report a separation result that obtains for an important case indicates that the initial pricing decision is independent of the auditing decision the auditing decision however depends on the price that was initially set the optimal auditing strategy is characterized and the nature of the welfare gains are identified the methodology used in the analysis involves the characterization of an equilibrium of a revelation game with an ex post observable

economic stabilization in the post crisis world are fiscal rules the answer abstract we investigate whether fiscal rules help to reduce the extent of policy procyclicality how government expenditure policy responds to gdp in a dynamic panel framework with 81 advanced emerging and developing countries over 1985 2012 we construct two new fiscal rule indices and investigate whether rules help to dampen procyclical policies we condition our empirical specifications on the degree to which governments appear able to manage and enforce fiscal rules we find that fiscal rules are very effective in reducing procyclicality of policy once a minimum threshold of government efficiency quality has been reached government efficiency alone is not enough to reduce procyclicality of fiscal policy however high government efficiency combined with strong fiscal rules is a potent combination facilitating counter cyclical policy responses to gdp movements

is there convergence in per capita so2 emissions in china an empirical study using city level panel data abstract as china s economy has grown rapidly in recent years china s environmental pollution has become increasingly significant among all the traditional pollutants sulfur dioxide has been monitored by the chinese government since the 1990s in this study china s city level panel data between 2002 and 2012 are utilized to investigate the existence of convergence in per capita sulfur dioxide emissions across chinese cities the conventional estimation methods for convergence suffer from an endogeneity problem and therefore produce biased results to address the endogeneity problem and allow for dynamics dynamic panel data estimators are utilized and the static estimation results are conducted as a robustness check in addition the influential factors for convergence are examined the empirical results indicate that in the chosen sample period there were absolute and conditional convergences in per capita sulfur dioxide emissions across cities within the whole nation as well as in the eastern western and central regions of china because per capita gross domestic product and the ratio of secondary industry to gross domestic product are both positively related with per capita sulfur dioxide emissions higher income per capita and greater importance of the secondary industry would cause the convergence speed to be lower therefore the most straightforward policy implication for the empirical results is that the policies for controlling sulfur dioxide emissions should be regionally differentiated for cities with high sulfur dioxide emissions per capita the regulation could be tight as the emissions would decrease faster because convergence exists however for cities with low sulfur dioxide emissions per capita the target for reducing emissions should not be excessively aggressive

the new stability and growth pact a first assessment abstract the paper proposes a theoretical model of fiscal policy offering new insights on some of the key policy trade offs involved in the recent reform of the stability and growth pact as suggested by the proponents of the reform greater room for case specific economic judgment in the implementation of the pact may improve welfare in our model these gains occur because the consolidation path implied by the implementation of the pact does not discourage high quality measures in practice however the difficulty to extract true policy intent from budget figures may hinder the qualitative assessment of fiscal policy hence reforming a rules based fiscal framework with a view to enhance its economic rationale would also require closer monitoring a better grasp of the policies underlying the budget and ultimately stricter enforcement in that sense recent reforms are at best unhelpful

fiscal rules and discretion under persistent shocks this paper studies the optimal level of discretion in policymaking we consider a fiscal policy model where the government has time inconsistent preferences with a present bias toward public spending the government chooses a fiscal rule to trade off its desire to commit to not overspend against its desire to have flexibility to react to privately observed shocks to the value of spending we analyze the optimal fiscal rule when the shocks are persistent unlike under independent and identically distributed shocks we show that the ex ante optimal rule is not sequentially optimal as it provides dynamic incentives the ex ante optimal rule exhibits history dependence with high shocks leading to an erosion of future fiscal discipline compared to low shocks which lead to the reinstatement of discipline the implied policy distortions oscillate over time given a sequence of high shocks and can force the government to accumulate maximal debt and become immiserated in the long run

carbon dioxide emissions intensity of portuguese industry and energy sectors a convergence analysis and econometric approach abstract given the relevance of energy and pollution issues for industrialised countries and the importance of industry and energy sectors to the achievement of their economic and environmental goals it is important to know if there is a common pattern of emissions intensity fuel intensity and energy intensity between industries to know if it justifies a more specific application of energy policies between sectors which sectors have the greatest potential for reducing energy use and which are the long term effects of those specific variables on the mitigation of emissions we found that although there is literature on decomposition of effects that affect emissions the study of the convergence and of the relationships between these variables does not include ratios or effects that result from the decomposition analysis thus the above questions are not answered much less for the portuguese reality the purpose of this paper is to study i the existence of convergence of some relevant ratios as carbon dioxide co 2 emissions intensity co 2 emissions by fossil fuel consumption fossil fuel intensity energy intensity and economic structure between industry and energy sectors in portugal and ii the influence that the consumption of fossil fuels the consumption of aggregate energy and gdp have on co 2 emissions and the influence that the ratios in which co 2 emissions intensity decomposes can affect that variable using an econometric approach namely panel corrected standard errors estimator we concluded that there is sigma convergence for all ratios with exception of fossil fuel intensity gamma convergence verifies for all ratios with exception of co 2 emissions by fossil fuel from the econometric approach we concluded that the considered variables have a significant importance in explaining co 2 emissions and co 2 emissions intensity

a signal jamming theory of predation we propose a new theory ofpredation based on signal jamming in our model the predator s characteristics are common knowledge while the entrant is uncertain of his own future profitability the entrant uses his current profit to decide whether to remain in the market and the predator preys to jam or interfere with this inference problem thus our model differs from those based on reputation effects in which the predator preys to signal information about himself

assessing the decoupling of economic growth from environmental impacts in the european union a consumption based approach abstract pursuing a responsible and sustainable development the united nations urged to decouple economic growth from environmental impacts several european union eu policies have been implemented towards such goal although multiple authors have evaluated the decoupling of the economic growth from the resource use or environmental concerns the environmental assessment mostly focused on pressures rather than impacts and used single indicators assumed to be a proxy of the overall effects on the environment furthermore no studies were found using a process based life cycle approach to quantify the environmental impacts of consumption to solve such research gap this paper assesses the decoupling in the eu focusing on potential environmental impacts complementing a production based approach with two options for accounting for the impacts of consumption the aim of this paper is to evaluate the decoupling of the economic growth in terms of gross domestic product from the environmental impacts due to eu 28 consumption assessed by means of life cycle assessment lca the decoupling is then assessed in impact terms rather than limited to pressures by using the environmental footprint ef2017 indicators which allows assessing 16 different impacts the consumption footprint indicator quantified the environmental impacts of eu apparent consumption including the territorial impacts domestic footprint and the embodied impacts in both imports and exports trade footprint the inventory of pressures for the trade component is compiled either with a bottom up approach process based lca of representative traded goods or a top down approach input output based lca methodological aspects influencing the decoupling assessment and the resulting outputs are presented and discussed according to the results the environmental impacts of eu 28 consumption showed decoupling during the last decades 2005 2014 between relative to absolute decoupling depending on the inventory modeling approach taken some countries showed higher decoupling levels than others displaying a heterogeneous map of eu 28 decoupling which was led by acidification particulate matter land use and eutrophication impacts notwithstanding current limitations the assessment of decoupling using consumption based environmental indicators is very promising for supporting policy making towards addressing the actual impacts driven by the eu production and consumption system

voting on the budget deficit this paper analyzes a model in which a group of rational individuals votes over the composition and time profile of public spending all voters agree that a balanced budget is ex ante optimal however if there is disagreement between current and future majorities a balanced budget is not a political equilibrium under majority rule under certain conditions a majority of the voters favors a budget deficit and the equilibrium deficit is larger the greater is the polarization among voters copyright 1990 by american economic association

the costs and benefits of balanced budget rules lessons from a political economy model of fiscal policy this paper analyzes the impact of a balanced budget rule that requires that legislators do not run deficits in the political economy model of battaglini and coate 2008 the main finding is that the rule leads to a gradual reduction in the level of public debt legislators reduce debt in periods when the demand for public goods is relatively low they do so because the rule by restricting future fiscal policies raises the expected costs of carrying debt whether the rule increases citizen welfare depends on a comparison of the benefits of a lower debt burden with the costs of greater volatility in taxes and less responsive public good provision a quantitative version of the model is developed in which costs and benefits can be evaluated a welfare loss results if the debt level when the rule is imposed lies in the support of the long run distribution associated with the unconstrained equilibrium

analysis of co2 emissions in apec countries a time series and a cross sectional decomposition using the log mean divisia method abstract we decompose the changes of co2 emissions in apec countries over time as well as the differences of co2 emissions among three income groups of apec countries at a given period of time based on the logarithmic mean divisia decomposition approach among the major findings of the paper the growth in per capita gdp and population are the two dominant contributors to the increase in co2 emissions in most cases furthermore energy efficiency and fuel switching are found to be the two most promising fields for possible cooperation between apec member countries

structural break unit root and the causality between energy consumption and gdp in turkey abstract this paper tries to investigate a series of unit root and causality tests to detect causality between the gdp and energy consumption in turkey employing hsiao s version of granger causality method for the 1950 2000 period the conventional unit root tests indicate the series are i 1 whereas the endogenous break unit root tests proposed by zivot and andrews zivot e and andrews d w k 1992 further evidence on the great crash the oil price shock and the unit root hypothesis journal of business and economics statistics 10 251 270 and perron perron p 1997 further evidence on breaking trend functions in macroeconomic variables journal of econometrics 80 355 385 reveal that the series are trend stationary with a structural break therefore it is inappropriate to take the first difference of the data to achieve stationarity the main conclusion of this study is that there is no evidence of causality between energy consumption and gdp in turkey based on the detrended data

balanced budget rules and fiscal outcomes evidence from historical constitutions this paper studies the long run fiscal consequences of balanced budget rules bbr that are enshrined in a country s constitution using historical data dating back to the 19th century and applying a difference in difference approach we find that the introduction of a constitutional bbr reduces government debt to gdp and expenditure to gdp ratios on average by around 11 and 3 percentage points respectively we do not find evidence that bbrs affect tax revenues our analysis indicates that such rules reduce the probability of experiencing a debt crisis and that the effective enforcement of bbrs can be conditional on the quality of democratic institutions in addition we implement an instrumental variable approach by instrumenting the probability of having budget rules on de jure constraints on changing the constitution this and other tests suggest that the relations we find are largely causal going from bbrs to fiscal outcomes
