The rise and fall of spatial inequalities in France: A long-run perspective

This paper studies the evolution and determinants of spatial inequalities in France. To this end, we use a unique database providing data on value-added, employment, and population over the entire set of French “Départements” in 1860, 1896, 1930, 1982, and 2000. These data cover three sectors: Agriculture, Manufacturing, and Services. Firstly, we confirm the existence of a bell-shaped process of spatial concentration in Manufacturing and Services over time. In contrast, labor productivity has been converging across departments. Secondly, we find considerable agglomeration economies over the whole period. The spatial distribution of these gains is determined mainly by market potential in the first sub-period, 1860–1930, and higher education in the second, 1930–2000.     

Wage Dispersion and Firm Productivity in Different Working Environments

This article investigates the impact of wage dispersion on firm productivity in different working environments. More precisely, it examines the interaction with: (i) the skills of the workforce, using a more appropriate indicator than the standard distinction between white‐ and blue‐collar workers, and (ii) the uncertainty of the firm economic environment, which has, to our knowledge, never been explored on an empirical basis. Using detailed cross‐sectional linked employer–employee data for Belgium, we find a hump‐shaped relationship between (conditional) wage dispersion and firm productivity. This result suggests that up to (beyond) a certain level of wage dispersion, the incentive effects of ‘tournaments’ dominate (are dominated by) ‘fairness’ and/or ‘sabotage’ considerations. Findings also show that the intensity of the relationship is stronger for highly skilled workers and in more stable environments. This might be explained by the fact that monitoring costs and production–effort elasticity are greater for highly skilled workers, and that in the presence of high uncertainty, workers have less control over their effort–output relation, and associate higher uncertainty with more unfair environments.     

Context matters to explain field experiments: Results from Colombian and Thai fishing villages

During the last decade, field experiments regarding the study of common pool resource governance have been performed that replicated earlier findings of laboratory experiments. One of the questions is how the decisions made by participants in rural communities are influenced by their experience. This paper presents the results of field experiments in Colombia and Thailand on fishery resources. Context information is derived from the communities via in-depth interviews, surveys and role playing exercises. The use of different methodological tools allowed to link decisions in field experiments with contextual variables for two fishery villages. Explanation of core variables in social dilemmas is given, the degree of cooperation levels, preferred rules, rule compliance and enforcement. Main findings include: i) fishermen made decisions in the field experiments that reflected their own experience and context, ii) agreements for rule crafting are possible only under specific conditions that guarantees livelihoods and sustainability, iii) the broader context determines cooperation levels at a local level, iv) inequalities in the sanctioning of rule breakers decrease the possibilities of reaching cooperation agreements, and v) high levels of trust among local fishermen is not a sufficient condition for resource sustainability, when trust in external rule makers and enforcers is low.     

The influence of international trade on labour productivity in services: The case of Brazil in the 1990s

In the developing world, services account for a rising share of domestic employment and international trade. Thus, it is important to know whether trade liberalization contributes to labour productivity in services. We explore this question, examining the 1990–2000 Brazilian trade liberalization. We find that growth of imports and exports strengthened labour productivity in services, but the contribution was smaller in subsectors with more college graduates, and this negative offset was larger in subsectors that received large foreign direct investment (FDI) inflows. Improved access to imported manufactured intermediate inputs raised downstream services' labour productivity and downstream manufacturing firms benefitting from tariff cuts enacted by trade partners generated spillovers that improved the labour productivity of upstream service subsectors. However, FDI inflows and investments in human and physical capital modified these downstream factors. We conclude that the Brazilian trade liberalization strengthened productivity in services, but unequally across subsectors.     

Does a Terroir Product Tell the Same Story to Tourists,Day‐trippers and Local Consumers? The Moderating Role of Variety‐seeking Tendency and Perceived Authenticity

The issue of segmentation of the culinary tourism market is central for local economic actors because many products and activities address several marketing targets, including tourists and residents. This research shows that the assessment of the attributes of a terroir cheese is not altered by the consumer's tourist status. In contrast, taking into account the underlying motivations behind culinary tourism, an individual variable (the variety‐seeking tendency) and a variable related to the product (its perceived authenticity) appear as relevant segmentation criteria for such a culinary tourism product.

Impact of completing chronic hepatitis C (CHC) treatment on post-therapy healthcare cost

Background:

Chronic hepatitis C (CHC) is associated with significant economic burden. This study evaluated the healthcare cost alleviation associated with treatment of CHC.

Methods:

Health insurance claims from 60 self-insured US companies were analyzed (01/2001–03/2012). Adult patients with ≥1 CHC diagnosis (ICD-9-CM: 070.44, 070.54), initiating interferon, and with ≥2 dispensings and with ≥48 weeks of follow-up were selected. Patients diagnosed with HIV or who completed only 24 weeks of interferon therapy (a surrogate for CHC genotypes 2 and 3) were excluded from the study. Interferon users were categorized into complete and discontinued therapy cohorts. During the post–48-week treatment period, cohorts were compared for healthcare resource utilization using rate ratios (RRs), as well as healthcare costs using per-patient per-year (PPPY) cost differences.

Results:

A total of 1017 patients who completed and 953 patients who discontinued interferon therapy were identified. Relative to the discontinued therapy cohort, the completed therapy cohort had significantly fewer hospitalizations (RR [95% CI]?=?0.74 [0.68, 0.81], p?p?p?=?0.039), which translated into significantly lower total healthcare costs PPPY (cost difference [95% CI]?=?$4540 [1570, 7680], p?=?0.004) and hospitalization costs (cost difference [95% CI]?=?$3039 [1140, 5248], p?=?0.002). Non–CHC-related costs accounted for 55% and CHC-related costs for 45% of the all-cause cost difference between cohorts.

Limitations:

Claims data may have contained inaccuracies, and genotypes of patients with CHC could not be confirmed. The study consisted of privately insured individuals and may not be generalizable to the entire CHC population.

Conclusion:

Compared to discontinued therapy patients, CHC patients who completed interferon therapy and presumably had a higher rate of achieving SVR were found to have lower levels of healthcare resource utilization and costs post-therapy. The reduction was primarily in costs associated with non–HCV-related comorbidities.     

The Value Relevance of Reputation for Sustainability Leadership

This study investigates whether the market valuation of the two summary accounting measures, book value of equity and net income, is higher for firms with reputation for sustainability leadership, when compared to firms that do not enjoy such reputation. The results are interpreted through the lens of a framework combining signalling theory and resource-based theory, according to which firms signal their commitment to sustainability to influence the external perception of reputation. A firm’s reputation for being committed to sustainability is an intangible resource that can increase the value of a firm’s expected cash flows and/or reduce the variability of its cash flows. Our findings are according to expectations and show that the net income of firms with good sustainability reputation has a higher valuation by the market, when compared to their counterparts.     

The impact of human capital on the early success of necessity versus opportunity-based entrepreneurs

This paper examines whether founders’ backgrounds influence new firm survival in the early years after startup, focusing, in particular, on the impact of unemployment-driven entrepreneurship. For entrepreneurs who left their previous employment to found a new firm, both general and specific human capital play a key role in enhancing early survival chances. However, various forms of human capital have little effect on early survival of unemployment-driven entrepreneurs, who rely mostly on previous entrepreneurial experience to persevere. Results suggest that pre-entry capabilities play an important role in the early success of opportunity-based entrepreneurs, but have little influence on the early success of necessity-based ones.     

A Socio-technical Approach for Group Decision Support in Public Strategic Planning: The Pernambuco PPA Case

This article describes a socio-technical approach to public strategic planning. A multi-methodological framework with decision support systems (DSS) of problem structuring, multi-criteria decision analysis and strategic thinking was used in a decision conferencing process to support the key-players of the Pernambuco State Department of Social Development and Human Rights, in Brazil, to elaborate its 2008–2011 Multi-Annual Plan (PPA). This interactive process took place in June 2007, with thirty technical and political actors meeting in 5 consecutive days to discuss what should be the fundamental objectives/development axes of the PPA and to generate, assess and classify intervention programmes to achieve the objectives. Structuring objectives and programmes started by a group causal mapping session supported by the Decision Explorer DSS. Then, a multi-criteria group value model, created on-the-spot by means of the M-MACBETH DSS, helped the politicians in evaluating the overall benefit of each programme. The doability of the programmes was also appraised with MACBETH and, finally, the programmes were classified into four benefit versus doability categories defined in a $2\times 2$ strategic graph: “pearls” (programmes with high benefit value and easy to implement), “oysters” (high benefit but difficult to implement), “bread and butter” (easy to implement but of low added value) and “white elephants” (low benefit and difficult to implement). The group agreed that at least all pearls and oysters should be selected. The programmes were prioritised based on their value-for-effort and the robustness of the selection was analysed with the PROBE DSS a posteriori.
