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.     

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.     

Is Latin America Catching Up? A Time‐Series Approach

Most Latin American economies ended the twentieth century further behind the United States (in terms of productivity) than they had been in 1950. We investigate whether this reflects the effect of occasional economic setbacks or a systematic tendency to fall behind the United States. This is done using a time‐series approach that allows for up to two structural breaks in a series. We find evidence that relative productivity is a (broken) trend‐stationary process for most of the 18 countries considered but that only one, Chile, shows evidence of catching up with the United States at the century’s close.     

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.     

Do tax cuts generate twin deficits? A multi‐country analysis

Abstract We study the effects of tax shocks on the budget and external deficits for 16 industrialized countries over the post‐1970 period. Our structural approach is based on a small open economy model where a tax cut affects the external deficit by two distinct channels. The demographic channel works through the overlapping‐generation structure of the model. The forecasting channel works through the dynamic structure of the model. Our empirical analysis documents that tax shocks generate twin deficits, and that both channels play important roles in explaining the positive comovement between the budget and external deficits.     

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.     

Non‐Linear Oil Price Dynamics: A Tale of Heterogeneous Speculators?

Abstract. While some of the recent surges in oil prices can be attributed to a robust global demand at a time of tight production capacities, commentators occasionally also blame the impact of speculators for part of the price pressure. We propose an empirical oil market model with heterogeneous speculators. Whereas trend-extrapolating chartists may tend to destabilize the market, fundamentalists exercise a stabilizing effect on the price dynamics. Using monthly data for West Texas Intermediate oil prices, our STR-GARCH estimates indicate that oil price cycles may indeed emerge due to the non-linear interplay between different trader types.     

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.     

Does public‐sector employment fully crowd out private‐sector employment?

Employment matters for development because it can raise household income, lower inequality, promote economic growth, and contribute to political stability. Many countries have high rates of public employment, but what effect does this have on overall employment and unemployment rates? This paper investigates if and to what extent public‐sector employment crowds out (reduces) private‐sector employment. In particular, we estimate regressions of unemployment or private‐sector employment on two measures of public‐sector employment. The study uses an especially assembled dataset, which is novel for its coverage of a large sample of developing countries as part of a panel of rich and poor countries. Our results point to full or just about full crowding‐out for the entire sample. Unlike previous cross‐country studies, which were restricted to advanced economies, we are able to show that these results also apply to developing countries, although crowding‐out may not be quite as high as in advanced economies. The results mean that high rates of public employment have an offsetting large negative impact on private employment rates and do not reduce overall unemployment rates. With the qualifier that government activities may help the economy in other ways, our results imply that, rather than creating public‐sector jobs, scarce fiscal resources could be better spent on other developmental needs.     

IS THE WIGWAM WORTH IT? A CONTINGENT VALUATION METHOD ESTIMATE FOR A SMALL‐CITY SPORTS ARENA

The public good benefits arising from an historic high school gymnasium are estimated using the contingent valuation method. While other works focus on larger cities and usually emphasize new buildings for professional teams, this study looks at an historic building for amateur sports. It is found that the benefits are small in spite of the importance of the building and high school sports in general to the history of the city. Because this gymnasium is particularly large and recognized, this would seem to give an upper bound to the value of sports arenas in cities of this size. (JEL H41, L83)     

A ONE‐SECTOR GROWTH MODEL WITH CONSUMPTION STANDARD: INDETERMINATE OR DETERMINATE?

In a representative agent, one-sector growth model in which the discounting is decreasing in the consumption standard measured as the current average consumption flow, Drugeon (1998) establishes local indeterminacy. This paper extends Drugeon's setup in the discount rate. In our setup, the consumption standard is a habit stock that a weighted average of the whole history of average consumption flows in the past. Local indeterminacy emerges only when the speed of habit formation tends to infinity; otherwise, local indeterminacy cannot appear, no matter how large the habit affects the discount rate.     

WOULD AUSTRALIA–NEW ZEALAND BE A VIABLE CURRENCY UNION? EVIDENCE FROM INTERSTATE RISK‐SHARING PERFORMANCES

In this article, we first measure the potential welfare gains from perfect risk sharing among Australian states and New Zealand regions under possible unification. We show that New Zealand regions reap moderate gains from perfect risk sharing when they form a union with Australia, whereas for Australian states, the gains are somewhat similar to what they have attained at the intranational level. Second, we measure the extent of interstate risk sharing and intertemporal smoothing between the two countries. We are able to observe a substantial degree of intertemporal smoothing among Australian states and New Zealand regions, either alone or jointly, thus confirming the permanent income hypothesis. Further, unique to the risk‐sharing literature, we decompose the aggregate (nondiversifiable) output shocks into positive and negative components, in order to assess the strength of risk‐sharing mechanisms across business cycles. The study finds a virtual absence of risk sharing when Australia and New Zealand face negative aggregate fluctuations, raising doubts about the feasibility of the union, particularly during economic downturns.

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.     

WAL‐MART AND BANKS: SHOULD THE TWAIN MEET? A PRINCIPLES‐BASED APPROACH TO THE ISSUES OF THE SEPARATION OF BANKING AND COMMERCE

The application in July 2005 by Wal-Mart to obtain a specialized bank charter from the state of Utah and to obtain federal deposit insurance reopened a national debate concerning the separation of banking and commerce. Though Wal-Mart withdrew its application in March 2007, the issue and the debate continue. This article offers a principles-based approach to this issue that begins with the recognition that banks are special and that safety and soundness regulation of banks is therefore warranted. Building on that recognition, the article lays out the principle that the "examinability and supervisability" of an activity should determine if that activity should be undertaken by a bank. Even if an otherwise legitimate activity is not suitable for a bank, it should be allowed for a bank's owners (whether the owners are individuals or a holding company), so long as the financial transactions between the bank and its owners are closely monitored by bank regulators. The implications of this set of ideas for the Wal-Mart case and for banking and commerce generally are then discussed . ( JEL G21, G28)     

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.     

THE USE OF PPP ARRANGEMENTS IN STREET LIGHTING: A WIN‐WIN OPTION?

Street lighting is a classic example of a public good, and governments are extensively involved in its provision. Adequate lighting facilitates both car traffic and personal safety while improving an urban area's character. However, many systems are mismanaged and obsolete, incurring high energy costs and emissions with relatively low lighting quality. Public authorities facing budget constraints often find retrofitting old street‐lighting systems challenging. They have two options: either direct in‐house, public‐authority renovation or contracting with a private company through a public–private partnership (PPP). Although private‐sector‐participation approaches vary, most public authorities can now enter into a street‐light modernization PPP agreement. That can be a win‐win option for both the public and private sectors. The upfront investment is small and operational expenses outweigh capital expenses, generating lower payback periods and energy‐cost reduction with light‐emitting diode (LED) technology. Little public expenditure is necessary when private partners are compensated via shared energy savings. We analyze the Detroit street‐light PPP – the United States’ first – and find that PPPs are practical for retrofitting US street lights and in other countries where they are antiquated.     

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.

DOES THE MISSION OF PROVIDERS MATTER ON A QUASI‐MARKET? THE CASE OF THE BELGIAN ‘SERVICE VOUCHER’ SCHEME

ABSTRACT 1 : In 2001, the Belgian government introduced a ‘service voucher’ scheme in the field of domestic (housework) services, following a quasi‐market mechanism which fosters competition between providers of different types as regards sector (for‐profit, public, third sector) and mission (seeking profits, home care provision to vulnerable groups and work integration of the unemployed). Empirical evidence suggests that third sector organizations focusing on a social mission recognized by a tutelary regulation are the best performing with regards to the quality of jobs and service organization, leading to a better ‘triangulation’ of the service relationship. On the other hand, for‐profit providers, especially temporary work agencies, seem to favour their capacity of adaptation to the desiderata of their clients and costs’ minimization to the detriment of the quality of jobs which are made as flexible as possible.     

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.
