The growth effects of tax rates in the OECD

This paper explores the merits of macro‐ and micro‐based tax rate measures within an open economy “fiscal policy and growth” model. Using annual data for 15 OECD countries we find statistically small, non‐robust long‐run growth effects of macro‐based average tax rates on capital income and consumption, but some evidence for average labour income tax effects. Changes in “micro” marginal income tax rates at both the personal and corporate levels yield statistically robust GDP responses of modest size. Both domestic and foreign corporate taxes appear relevant. In general, tax effects on GDP operate largely via factor productivity rather than factor accumulation.     

Risk sharing and industrial specialization in China

We investigate how risk sharing shapes industrial specialization across prefecture-level cities in China. By unbundling the mechanisms of risk sharing, we find that ex ante risk sharing generates a first-order stimulant effect on the geographical concentration of manufacturing industries, particularly for non-state-owned enterprises and cyclical industries. Ex post risk sharing matters only for state-owned enterprises. This result remains robust to instrument variable estimation and controlling for other determinants of industrial specialization. Finally, we show that interregional labor migration (special fiscal transfers) plays an important role in promoting interregional ex ante (ex post) risk sharing. The study implies that much more risk sharing and efficiency gains from industrial specialization would be achieved if capital markets and credit markets are better developed.     

Discrepancies between ex ante and ex post efficiency under identical subjective probabilities

Summary. Starr (1973) showed that, if people have different subjective probabilities, ex ante and ex post efficiency conflict. Conversely, under the simple preferences that he considered, the discrepancy between ex ante and ex post efficiency disappears when subjective probabilities are identical. Here I consider identical subjective probabilities, but more general preferences. First, risk attraction is admitted. Second, I dispense with the double requirement (dubbed IZU) of additive separability and state-independence of the utility of zero-date consumption, an unrealistic requirement when modeling the investment in durable goods. I find that, under IZU, and as long as ex post preferences satisfy the natural assumption of quasiconcavity (and satisfy some technical qualifications), an ex ante efficient allocation is indeed ex post efficient, but the converse is not necessarily true under risk attraction. If, on the other hand, IZU is violated, then one can have ex ante efficient allocations that are not ex post efficient, and vice-versa, even under risk aversion.

MEASURING VARIATIONS IN LIFETIME WELFARE EX ANTE AND EX POST: SOME EXPLORATORY CALCULATIONS

Whereas longevity‐adjusted consumption measures have become increasingly used as indicators of lifetime standards of living, it remained unnoticed that those measures, by relying on period – rather than cohort – life tables, constitute indicators of expected – rather than actual – lifetime standards of living. In order to estimate the actual gap between ex ante and ex post measures of lifetime welfare, this paper computes, for 19th‐century European economies, longevity‐adjusted consumption measures based on period and cohort life tables. It is shown that the gap between ex ante and ex post measures is statistically significant, and that attempts to reduce it are likely to be unsuccessful, because standards of living tend to exhibit, over temporal horizons as long as a human life, structural breaks, which make the ex ante measurement of lifetime welfare highly speculative.     

Hybrid Contests

This paper examines hybrid contests where participants commit two types of resources to improve their probability of winning the prize. The first type is forfeited ex ante, before the prize is allocated, by winners and losers alike, while the second is committed ex ante by all contenders but expended ex post, after the prize is allocated, and only by the contestant that wins the prize. The model yields a number of interesting results. Among them is the finding that, as the number of contestants increases, the ex ante expenditures of individual contestants decrease while the ex post expenditure increases. Even more interesting, the total of the ex ante and ex post expenditures by the contenders in a hybrid contest may decrease with the number of competitors. The study also finds that there is no rent overdissipation, and compares the total expenditures in the contest and “all‐pay” allocation mechanisms.     

Exploring causal relationships in an innovation program with Robust Portfolio Modeling

Many countries seek to foster the commercial exploitation of science-based research results through selective policy instruments. Typically, these instruments involve processes of follow-up data collection where the results of ex ante and ex post assessments are systematically recorded. Yet, several factors – such as the presence of multiple objectives, predominance of qualitative data and missing observations – may complicate the use of such data for adjusting the management practices of these instruments. With the aim of addressing these challenges, we adopt Robust Portfolio Modeling¹ (RPM) as an evaluation framework to the analysis of longitudinal data: specifically, we (i) determine subsets of outperforming and underperforming projects through the development of an explicit multicriteria model for ex post evaluation, and (ii) carry out comparative analyses between these subsets, in order to identify which ex ante interventions and contextual characteristics may have contributed to later performance. We also report experiences from the application of RPM-evaluation to a Finnish innovation program and outline extensions of this approach that provide further decision support to the managers of innovation programs.     

The cyclical behaviour of fiscal policy: evidence from the OECD

This paper addresses the topic of cyclicality in fiscal policy. In particular, we show that the level of cyclicality varies across spending categories and across OECD countries. In line with leading theories of fiscal cyclicality, we show that countries with volatile output and dispersed political power are the most likely to run procyclical fiscal policies. Wage government consumption is highlighted as the most important channel by which these variables affect fiscal cyclicality.     

Barriers to Global Free Trade through Bilateral Agreements

This paper examines the formation of bilateral free trade agreements (FTAs) in the context of a dynamic noncooperative bargaining game with a random proposer. We show that global free trade (a grand coalition) does not necessarily occur unless transfer payments among countries are allowed. When transfer payments are possible, bilateral FTAs always achieve global free trade, but the ex‐ante and ex‐post inequalities of social welfare among countries are larger than those when all countries are independent because of the strategic bargaining behavior.     

Uncertainty,Learning and Heterogeneity in International Environmental Agreements

This paper concerns the formation of International Environmental Agreements under uncertainty about environmental damage with different models of learning (complete learning, partial learning or no learning). The results of the existing literature are generally pessimistic: the possibility of either complete or partial learning generally reduces the level of global welfare that can be achieved from forming an IEA relative to no learning. That literature regards uncertainty as a parameter common to all countries, so that countries are identical ex ante as well as ex post. In this paper we extend the literature to the case where there is no correlation between damage costs across countries; each country is uncertain about a particular parameter (in our case the benefit-cost ratio) drawn from a common distribution but, ex post, each country’s realized parameter value is independently drawn. Consequently, while countries remain identical ex ante, they may be heterogeneous ex post. We show that this change reinforces the negative conclusions about the effects of partial learning on international environmental agreements, but, under certain conditions, moderates the negative conclusions about the effects of complete learning.     

Is Fiscal Policy Procyclical in the Euro Area?

We test the relationship between the cyclically adjusted primary balance and alternative indicators of cyclical conditions for the euro area and 18 OECD countries over the period 1970–2009. A countercyclical stance of discretionary fiscal policy is found during bad times after 1999 in the euro area as a whole and in a few member countries only (France, Ireland and The Netherlands). It is also associated with high public deficits or low public debts. There is no significant case of procyclical fiscal policy after 1999, neither in good times nor in bad times.     

The cyclicality of fiscal policy: New evidence from unobserved components approach

This paper employs the multivariate version of the unobserved components model to reinvestigate the cyclicality of fiscal policy in eleven OECD countries. The novelty of the multivariate approach lies in its superior ability to disentangle the correlations in cycles from the correlations in slopes of the relevant variables while allowing for those correlations in the model. The results suggest that fiscal policy is mildly counter-cyclical in seven of the eleven countries analyzed which resonates with the standard Keynesian models. However, the slope (growth) of government consumption is found to be positively correlated with real GDP in these economies. There is no evidence of procyclical fiscal policies in any of these eleven industrial countries. The results remain robust when we use subsamples and an alternative fiscal policy variable.     

Are you hiring Johnny Football or Johnny Doe? Uncertain labour quality and the measurement of monopsony in college football

I assess monopsony in the college football labour market as it relates to both typical and elite performers, while also accounting for the uncertain performance quality of prospective players who are in this labour market. Existing studies suggest that the marginal revenue product (MRP) of elite collegiate players later drafted into the National Football League (NFL), significantly exceeds their compensation. These comparisons overstate monopsony rents because schools don’t know ex ante which prospects will become these elite performers. Using financial data spanning 2004–2011 from 114 major schools, I estimate the MRP of players sorted into three ex post quality tiers, and find that while eventual NFL draftees generate revenue that significantly exceeds their compensation, a majority of scholarship players do not. Then, using Rivals.com talent ratings of 6,604 prospective players recruited from 2002–2008, I estimate the probability that prospects will reach each ex post quality tier given their ex ante ratings. MRP estimates are adjusted by these conditional probability estimates to reflect the expected MRP of prospects, which allows more appropriate assessment of monopsony rents. I find that schools possess substantially less monopsony power than unadjusted MRP estimates suggest.     

FISCAL POLICY AND ASSET PRICES

We analyse the impact of fiscal policy on asset prices using a panel vector auto‐regressive (PVAR) approach and quarterly data for ten industrialized countries. We find that positive fiscal shocks lead to a temporary fall in stock prices and a gradual and persistent decrease in housing prices. The empirical findings also point to: (i) a contractionary effect of fiscal policy on output in line with the existence of crowding‐out effects and the deterioration of credit conditions; (ii) a weakening of the effectiveness of fiscal policy in recent times; (iii) a more persistent response of asset prices for countries with a lower degree of openness; (iv) a larger impact of fiscal policy on asset prices for small countries; (v) a close link between the responsiveness of asset prices to fiscal policy and the government’s size; (vi) an increase of the sensitivity of asset prices to fiscal policy shocks following the process of financial deregulation and mortgage liberalization; and (vii) significant fiscal multiplier effects in the context of severe housing busts. Finally, the evidence suggests that changes in equity prices may help governments towards consolidation of public finances.     

RIGHT ON TARGET: EXPLORING THE FACTORS LEADING TO INFLATION TARGETING ADOPTION

This paper examines which economic, fiscal, external, financial, and institutional characteristics of countries affect the likelihood that they adopt inflation targeting (IT) as their monetary policy strategy. We estimate a panel binary response model for 60 countries and two subsamples consisting of Organization for Economic Cooperation and Development (OECD) and non‐OECD countries over the period 1985–2008. The findings suggest that past macroeconomic performance of a country, its fiscal discipline, exchange rate arrangements, as well as the structure and development of its financial system have a significant impact on the likelihood to adopt IT. However, the factors leading to IT adoption differ significantly between OECD and non‐OECD countries. (JEL E42, E52)     

Private investment with social benefits under uncertainty: The dark side of public financing

We develop a game‐theoretic model of private–public contribution to a long‐term project with sequential actions and moral hazard. A private agent is one who is in charge of both the financial contribution and the management effort, these two actions entailing private costs and uncertain ex‐post private and social benefits. A public agent is one who decides the amount of public funding to this quasi‐public good, knowing that the size and the probability of attaining a surplus ex post depend on the private agent's effort. We consider four public‐funding scenarios: benefit‐sharing versus cost‐sharing crossed with ex‐ante versus ex‐interim government intervention. We test our theoretical predictions by means of an experiment that confirms the main result of the model: Cost‐sharing public intervention is more effective than benefit‐sharing in boosting private financial contribution to the project. Furthermore, when public intervention comes after private contribution ( ex‐interim government intervention), both public‐funding scenarios have a negative impact on the private management effort. In our model, the latter result is explained by the private agent's high degree of risk aversion. These results have policy implications for strategic investments with long‐term social consequences. In deciding the optimal timing and method of the contribution, governments should also consider the indirect effects on agents’ long‐term management efforts.     

The Nature of Financial and Real Business Cycles: The Great Moderation and Banking Sector Pro‐Cyclicality

This study takes a fresh look at the nature of financial and real business cycles in OECD countries using annual data series and shorter quarterly economic indicators. It first analyses whether the last cycle has been different compared to previous cycles in terms of length, amplitude, asymmetry and changes of these parameters during expansions and contractions. We also study the degree of economic and financial cycle synchronization between OECD countries but also of economic and financial variables within a given country and gauge the extent to which cycle synchronization changed over time. We next describe the connection between the great moderation and the last cycle. Finally, the study discusses the synchronization between the real economy and the financial sector and provides some new evidence on the banking sector's pro‐cyclicality by using aggregate and bank level. The main findings show that the amplitude of the real business cycle was becoming smaller during the great moderation, but asset price cycles were becoming more volatile. In part, this was linked to developments in the banking sector which tended to accentuate pro‐cyclical behaviour. Greater synchronization of cycles may help explain the severity of the crisis.     

The dual nature of public goods and congestion: the role of fiscal policy revisited

Abstract The role of fiscal policy is examined when public goods provide both productive and utility services. In the presence of congestion, the consumption tax is shown to be distortionary. Optimal fiscal policy involves using consumption‐based instruments in conjunction with the income tax. An income tax‐financed increase in government spending dominates both lump‐sum and consumption tax‐financing. Replacing the lump‐sum tax with an income tax to finance a given level of spending dominates introducing an equivalent consumption tax. These results contrast sharply with the literature, where the consumption tax is generally viewed as the least distortionary source of public finance.     

Optimal Universal and Categorical Benefit Provision with Classification Errors and Imperfect Enforcement

We determine the optimal combination of a universal benefit and categorical benefit when individuals differ in their ability to work and, if able to work, their productivity. The categorical benefit is conditioned ex ante on applicants being unable to work and ex post on recipients not working. The awards test makes Type I/II errors. If the ex post condition is (i) not enforced, the optimal categorical benefit is positive only if the awards test has discriminatory power, while maximum welfare falls with both error propensities; but if (ii) fully enforced, the optimal categorical benefit is positive always and maximum welfare can increase with the Type II error propensity.     

Fiscal stabilizations: When do they work and why

This paper studies the determinants and channels through which fiscal contractions influence the dynamics of the debt-to-GDP ratio and GDP growth. Using data from a panel of OECD countries, the paper shows that the success of fiscal adjustments in decreasing the debt-to-GDP ratio depends on the size of the fiscal contraction and less on its composition. The rate of growth of output matters too, but higher GDP growth does not drive the success of a fiscal stabilization. In contrast, whether a fiscal adjustment is expansionary depends largely on the composition of the fiscal maneuvre. In particular, stabilizations implemented by cutting public spending lead to higher GDP growth rates. The effects of the composition on growth work mostly through the labor market rather than through agents’ expectations of future fiscal policy. Finally, the evidence suggests that successful and expansionary fiscal contractions are not the result of accompanying expansionary monetary policy or exchange rate devaluations.
