Is there a Laffer curve between aggregate output and public sector employment?

This paper develops a model of the relationship between public sector employment, total output and aggregate real demand in market prices, where public employment has a positive productivity effect on private output. Public employment crowds out private employment and output because its increase induces higher wages and taxes. The valuation of government output is also taken into account. While public employment affects total output and aggregate real demand in an a priori ambiguous way, numerical simulations suggest that the relationship may be nonlinear; positive, when public sector is “small” and negative, when it is “large”. Using the annual data from 22 OECD countries over the period 1960–1996 and estimating and testing for threshold models and more commonly used specifications with multiplicative interaction terms give support to this nonlinearity hypothesis between public employment and private sector output.

How does entry regulation influence entry into self‐employment and occupational mobility?1

We analyse how an entry regulation that imposes a mandatory educational standard affects entry into self‐employment and occupational mobility. We exploit German reunification as a natural experiment and identify regulatory effects by comparing differences between regulated and unregulated occupations in East Germany with the corresponding differences in West Germany after reunification. Consistent with our expectations, we find that entry regulation reduces entry into self‐employment and occupational mobility after reunification more in regulated occupations in East Germany than in West Germany. Our findings are relevant for transition or emerging economies as well as for mature market economies requiring large structural changes after unforeseen economic shocks.     

HOW IMPORTANT ARE TERMS‐OF‐TRADE SHOCKS?

According to conventional wisdom, terms‐of‐trade shocks represent a major source of business cycles in emerging and poor countries. This view is largely based on the analysis of calibrated business‐cycle models. We argue that the view that emerges from empirical structural vector autoregression (SVAR) models is strikingly different. We estimate country‐specific SVARs using data from 38 countries and find that terms‐of‐trade shocks explain less than 10% of movements in aggregate activity. We then estimate key structural parameters of a three‐sector business‐cycle model country by country and find a disconnect between the importance assigned to terms‐of‐trade shocks by theoretical and SVAR models.     

Competition in the traditional sector does not matter for the ‘Core–Periphery’ model

We modify Paul Krugman’s (1991) ‘Core–Periphery’ model by replacing the traditional competitive sector with a monopolistically competitive one. We show that the structure of spatial equilibria remains the same as in the original model. This result continues to hold true under Cournot or Bertrand oligopolistic competition with free entry in the traditional sector. The key factor that explains why the nature of competition in the traditional sector does not matter for the spatial equilibria is constant expenditure shares–due to nested Cobb–Douglas and CES preferences–which imply that trade in the traditional sector is independent from its sectoral characteristics.     

LA POLITIQUE BUDGÉTAIRE ÉVINCE‐T‐ELLE L’INVESTISSEMENT PRIVÉ AU BÉNIN?

RESUME : Cet article analyse les effets de la politique budgétaire sur l’investissement privé au Bénin à l’aide de deux modèles économétriques (l’approche par le flux d’investissement public et l’approche par le capital public), estimés en utilisant les outils d’économétrie avancée tels que les tests de racine unitaire et de cointégration et en appliquant la procédure en deux étapes suggérée par Engle et Granger (1987) . Nos résultats indiquent que la politique fiscale mais aussi le stock permanent de capital privé et le crédit au secteur privé favorise l’investissement privé. Cependant, la formation de capital public et les dépenses de consommation publique évincent l’investissement privé.     

What makes a successful export? Evidence from firm‐product‐ level data

Abstract We analyse a very rich and unique panel database that provides information on exports at the firm‐product level. Motivated by the recent theory of multi‐product firms, we investigate what determines the survival of products in the export mix to find that, in export dynamics, characteristics of the product as well as that of the firm matter. In particular, firm productivity as well as product scale and tenure are associated with a higher export survival rate. This suggests, in line with theory, that there are firm‐ as well as firm‐product‐specific competencies that are important for shaping firms’ export mix.     

IS MARKET‐ORIENTED REFORM PRODUCING A ‘TWO‐TRACK’ EUROPE? EVIDENCE FROM ELECTRICITY AND TELECOMMUNICATIONS

ABSTRACT: The European Commission has formally recognized that adequate provision of basic household services, including energy, communications, water and transport, is key to ensuring equity, social cohesion and solidarity. Yet little research has been done on the impact of the reform of these services in this regard. This article offers an innovative way to explore such questions by analyzing and contrasting stated and revealed preferences on citizen satisfaction with and expenditure on two services, telecommunications and electricity, in two large countries, Spain and the UK. We find evidence that in telecommunications, but not in electricity, reform has led to a ‘two‐track’ Europe, where citizens who are elderly, not working or the less‐educated behave differently in the market, with the result that they are less satisfied with these services than their younger, working, better‐educated, counterparts.     

Do South‐South trade agreements increase trade? Commodity‐level evidence from COMESA

Abstract .  South-South trade agreements are proliferating. Yet the impact of these agreements is largely unknown, as existing North-North and North-South micro-level studies are likely to yield misleading predictions for South-South trade agreements. This paper estimates the impact of COMESA on Uganda's imports between 1994 and 2003. Detailed import and tariff data at the 6-digit Harmonized System level are used for more than 1,000 commodities. Based on a difference-in-difference estimation strategy, the paper finds that – in contrast to evidence from aggregate statistics – COMESA's preferential tariff liberalization has not considerably increased Uganda's trade with member countries, on average, across sectors. The effect, however, is heterogeneous across sectors. Finally, the paper finds no evidence of trade-diversion effects.     

Do German Welfare‐to‐Work Programmes Reduce Welfare Dependency and Increase Employment?

Abstract. During the last decade, many Western economies reformed their welfare systems with the aim of activating welfare recipients by increasing welfare‐to‐work programmes (WTWP) and job‐search enforcement. We evaluate the short‐term effects of three important German WTWP implemented after a major reform in January 2005 (‘Hartz IV’), namely short training, further training with a planned duration of up to three months and public workfare programmes (‘One‐Euro‐Jobs’). Our analysis is based on a combination of a large‐scale survey and administrative data that is rich with respect to individual, household, agency level and regional information. We use this richness of the data to base the econometric evaluation on a selection‐on‐observables approach. We find that short‐term training programmes, on average, increase their participants' employment perspectives. There is also considerable effect heterogeneity across different subgroups of participants that could be exploited to improve the allocation of welfare recipients to the specific programmes and thus increase overall programme effectiveness.     

WILL TAX‐BASED HEALTH INSURANCE REFORMS HELP THE SELF‐EMPLOYED STAY IN BUSINESS?

The self‐employed face a tax‐induced disadvantage relative to wage and salary workers when it comes to the payment of health insurance premiums. This paper uses a panel of individual tax return data to test whether lower health insurance premium costs because of an expanded tax incentive result in longer periods of self‐employment. The results suggest that households claiming the deduction are indeed less likely to exit self‐employment. Equalizing the treatment of health insurance premiums for the self‐employed and wage workers by allowing full deductibility from Self‐Employment Contributions Act (SECA) taxes would result in a 7% decrease in the probability of exit.

ARE COOPERATIVES MORE PRODUCTIVE THAN INVESTOR‐OWNED FIRMS? CROSS‐INDUSTRY EVIDENCE FROM PORTUGAL

We analyse empirically whether cooperatives and investor‐owned firms differ in terms of productive efficiency. Using rich Portuguese panel data covering a wide range of industries, we apply two different empirical approaches to estimate potential differences in productive efficiency. The results from our benchmark random‐effects model show that cooperatives are significantly less productive, on average, than investor‐owned firms, both at the aggregate level and for most of the industries considered. However, the results derived from a System‐GMM approach, which is our preferred empirical strategy, are much less conclusive, and we cannot conclude that cooperatives are generally less efficient that investor‐owned firms. With either approach, though, we find no evidence that cooperatives are more productive than investor‐owned firms in any industry.     

Employed unemployed? On shadow employment in transition

Unregistered employment poses two types of challenges to the researchers: (1) reliably evaluating the wage differential between formally and informally employed and (2) accounting for the push and pull factors in general and the effects of business cycle in particular. We address the former with the use of propensity score matching and analyse the evolution of the estimated average compensations and the differentials with reference to GDP and unemployment fluctuations. Using 13 years of quarterly labour force survey data from Poland of de iure unemployed but de facto employed individuals we find, that in-the-shadow compensations tend to be higher and procyclical. We also find considerable distributional heterogeneity.     

Political cycles in Greece’s municipal employment

We consider the politically motivated fluctuations in Greece’s municipal employment, constructing a data-set from primary data and focusing on the composition of municipal employment in terms of employment relationship forms. Our analysis produces strong evidence of pre-electoral manipulation through increases in the number of contract employees. Considering a number of control variables and robustness checks does not affect the key results. Such variables include whether mayors run for reelection, incumbents’ political alignment with central government, partisan shifts, general elections, mayors’ turnover rate, and timing patterns. Our evidence provides insights into Greece’s political economy in the run-up to the current economic crisis.     

Economic Growth in Canada and the United States: Supply‐Push or Demand‐Pull?

Understanding the nature of structural change and the sources of economic growth of an economy, especially the relative importance of different industries, is essential for policy‐making. This paper estimates industry contribution to economic growth in both Canada and the United States. It argues that industry contribution should be evaluated on the basis of the performance of an industry in terms of creating economic value relative to other industries. In particular, it calls for the quantity and the price effects, which is consistent with real GDP in the chained‐Fisher index that values the industry more when its price rises and less when its price declines. This is an important departure from the traditional methodologies that consider only quantity effect. This paper shows that the contribution from demand‐driven industries is significantly more than the finding based on traditional thinking.     

How does informal employment impact income inequality?

This study investigates how informal employment impacts total income inequality in urban China. Finite mixture methodology is employed to examine the segments that exist in the informal labour market, and the Theil index (T0) is used to break down total income inequality according to different subsamples. We found that the two-segment model (upper-tier and lower-tier) best describes the structure of the informal labour market in urban China and that the upper-tier segment contributes most to the total income inequality.     

Did the Hartz Reforms Speed‐Up the Matching Process? A Macro‐Evaluation Using Empirical Matching Functions

Abstract. Starting in January 2003, Germany implemented the first two so-called Hartz reforms, followed by the third and fourth packages of Hartz reforms in January 2004 and January 2005, respectively. The aim of these reforms was to accelerate labor market flows and reduce unemployment duration. Without attempting to evaluate the specific components of these Hartz reforms, this paper provides a first attempt to evaluate the overall effectiveness of the first two reform waves, Hartz I/II and III, in speeding up the matching process between unemployed and vacant jobs. The analysis is conceptually rooted in the flow-based view underlying the reforms, estimating the structural features of the matching process. The results indicate that the reforms indeed had an impact in making the labor market more dynamic and accelerating the matching process.     

Are sequential round‐robin tournaments discriminatory?

I examine sequential round‐robin tournaments with three and four symmetric players. Each player is matched once with each other player and each match is organized as a Tullock contest. A single prize is allocated to the player with the most matches won. I show that, depending on the position of their matches in the sequence of the tournament, the players' ex ante winning probabilities and expected payoffs differ. Compared to tournaments with matches organized as all‐pay auctions, however, discrimination is weaker and partially reversed. Moreover, aggregate effort in tournaments with suitable Tullock contests is larger than in tournaments with all‐pay auctions. The fairness of round‐robin tournaments may be improved by an endogenous sequence of matches or the requirement that players fix their effort ex ante.     

CAN SECRET INTERVENTION BE COMPATIBLE WITH A NON‐PROFITMAKING CENTRAL BANK AND A FUNDAMENTAL‐CONSISTENT TARGET?

The coexistence of secret intervention operations and “the signaling channel” (Mussa. The Role of Official Intervention, 1981) seems confusing. Vitale ( Journal of International Economics, 49, 1999, 245–267) resolves this puzzle by employing an asymmetric information framework and an assumption of a fundamental‐inconsistent target for the exchange rate. Ferré and Manzano ( International Journal of Finance and Economics, 14, 2009, 378–393) follow Vitale's microstructure framework and argue that the central banks' profitability motivation offers a rationale for their secret intervention even under a target consistent with the fundamentals. However, that the authority uses its superior information to obtain speculative profits through secret intervention in the market is not a typical goal for central banks. To theoretically explain the opaqueness in non‐profitmaking central banks' exchange rate policies, we employ a model of a central bank's optimization by considering that no bank really knows the exact fundamental rate and they take into account the possible bad consequences of announcing the intervention. We also show that, in passing the bank's private information to market participants, a bank's announcement of the intervention size is equivalent to revealing its target rate. (JEL E58, F39)     

Do Merger Laws Deter Cross‐Border Mergers and Acquisitions?

Cross‐border merger and acquisition (M&A) flows have surged since the early 1990s. In the meanwhile, more and more countries have passed merger laws that regulate M&A. We propose a gravity model to examine the influence of merger law on cross‐border M&As. Based on a data set on cross‐border deals from 1985 to 2015, we find that merger regulation has a deterrence effect on cross‐border M&As. We show the robustness of our results in a number of tests, including using different measurements of cross‐border M&A activity and merger law. We also document a heterogeneous effect on member countries of the Organization for Economic Co‐operation and Development.     

Is the model “loans‐plus‐savings” better for microfinance in Eastern Europe and Central Asia? A propensity score matching comparison

Microfinance institutions are gradually evolving into multiservice organizations offering not only loans but also savings, and other financial and nonfinancial services. We contribute to the literature aimed at identifying how combining credit with savings affects outreach and sustainability in microfinance institutions (MFIs). We apply the propensity score matching method as well as its augmented dose–response version to compare the performance of loans‐plus‐savings MFIs with that of lending‐only in a sample of 710 observations from Eastern Europe and Central Asia. Owing to our unique capital structure data, we control for the use of subsidized capital, which related work ignores while existing evidence points to tradeoffs between subsidies and savings. We find that financial performance and breadth of outreach are positively associated with savings mobilization, while the evidence on depth of outreach points to a possible mission drift.
