Tacit collusion with imperfect monitoring in the Canadian manufacturing industry: an empirical study

This article undertakes a cross-sectoral analysis of a salient empirical implication of the model of tacit collusion advanced by Abreu, Pearce, and Stachetti (1986). Specifically, we assess the prevalence of a first-order Markovian process for alternating between price wars and collusive periods through nonparametric tests. The analysis focuses on 30 different industries in Canada. The evidence provides weak support for optimal collusion in one industry, which is consistent with the idea that such kind of collusive arrangements is unusual, or, if collusion is all too common, that price wars as deviations from collusion are rare.     

Environmental Analysis of Packaging for Soft Drinks Using the Life Cycle Assessment Methodology

The knowledge of a product＇s life cycle is the first step on the search of sustainable development. The life cycle assessment （LCA） is an important method because it allows an environment accounting, where the extraction of natural resources and energy of the nature are considered and the ＂returns＂ to the same one and allows in evaluating relative potential the environment impacts generated. The present work had as objective to make an analysis of material and energy flows of the life cycle of three types of packaging for soft drinks： glass bottles of 390 mL, aluminum cans of 350 mL, and bottles of PET of 2,000 mL. The study considered processes since the extraction of raw materials for production of the packaging until the stages of recycling, after the consumption of the soft drink. For the research, an inventory analysis followed the LCA methodology. The main critical points of generation of negative environmental impact during the life cycle of each packaging had been the identified and quantified data in this study. The consumption of natural resources like water and other raw materials and energy, the generation of atmospheric emissions, solid wastes and wastewaters had been the analyzed categories. The results showed that, in accordance with the scenes and defined variables, the most important conclusion was that the bottle of glass presented a less favorable scene to the environment in comparison with other packaging.     

Intertemporal Budget Policies and Macroeconomic Adjustment in Indebted Open Economies

This paper analyzes the role of government intertemporal budget policies in a growing open economy including nominal assets in the presence of an upward sloping supply of debt. This introduces transitional dynamics that influence the effects of government policy instruments on economic growth and the long term fiscal liability. It is shown that capital income taxes or a combination of tax‐cum‐expenditure or government expenditure alone can balance the long term intertemporal government budget constraint. However, those results are shown to depend critically upon the extent of distortion in capital flows brought about the upward sloping supply of debt.

After the wars of independence in the first half of the nineteenthcentury, Latin American countries embarked on a process of insertioninto the world economy, opening their doors to foreign investmentand specializing in the exportation of raw materials. In freemarkets and in an alignment with the British imperial economicsystem, Latin American elites saw a road for economic prosperityand political stability. Between the 1880s and 1914, Latin Americabecame more integrated into the     

Pro-poor trade policy in Sub-Saharan Africa

This paper examines the presence of a pro-poor bias in the existing structure of protection of six Sub-Saharan African (SSA) countries, Burkina Faso, Cameroon, Côte d'Ivoire, Ethiopia, Gambia, and Madagascar. We build on a simple agricultural household production model and we propose an extension to include adjustments in labor income. Our approach, which can be implemented without repeated cross-sections of household level data, suits well the data constraints in SSA. It also allows us to capture the heterogeneity in trade protection at the tariff line level. The pro-poor bias indicators suggest that SSA's trade policies tend to be biased in favor of poor households, as these policies redistribute income from rich to poor households. This is because protection increases the agricultural prices of goods that are sold by African households and this effect dominates both the impacts of higher consumption prices and the strong Stolper–Samuelson effects that benefit skilled over unskilled workers.     

Determinants of hierarchical structure in industrial firms: an empirical study

The paper investigates implications of different theoretical models for hierarchical structure. A sample of 6,578 firms in the Brazilian manufacturing industry is considered and explanatory factors pertaining to structural characteristics, network technology, technological innovations, managerial innovations and incentive mechanisms are investigated. Important joint effects are detected for all groups of variables in partial contrast with the related previous literature. Moreover, one detects significant joint effect of the newly considered group of incentive variables. The evidence in terms of individual effects is largely consistent with the predicted effects from the theoretical literature.     

Determinants of firm start-up size in the Brazilian industry: an empirical investigation

The article investigates the determinants of newly created industrial establishments in Brazil in 1997 taking as reference explanatory variables referring to market structure and industry dynamics, stronger effects are detected for larger firms. Minimum efficient scale, industry size, industry growth and turbulence display the expected positive effects on firm size, but the intensity of those are more pronounced for larger firms. The suboptimal scale variable, on the other hand, exhibits a counterintuitive positive effect and perhaps other types of barriers to entry that are not related to scale aspects may be important in the Brazilian case.     

Attitudinal loyalty and trust in entrepreneurship: building new relationships

This paper studies the impact of attitudinal loyalty and trust in entrepreneurship, following a client-focused strategy. In this context, trust and commitment are the cornerstone of relationship marketing, and contributes positively to achieving attitudinal loyalty, which is suitable for the maintenance of relationships over time. This variable also acts as a facilitator or mediator on the influence satisfaction has on loyalty. We show that satisfaction has a positive impact on trust and attitudinal loyalty. Following structural equation modelling methodology we test all the relationships in a sample composed by travel agency customers.     

Note on the existence and modulus of continuity of the {\textit{SLE}}_8 curve

We review one method for estimating the modulus of continuity of a Schramm–Loewner evolution (SLE) curve in terms of the inverse Loewner map. Then we prove estimates about the distribution of the inverse Loewner map, which underpin the difficulty in bounding the modulus of continuity of SLE for $\kappa =8$ . The main idea in the proof of these estimates is applying the Girsanov theorem to reduce the problem to estimates about one-dimensional Brownian motion.     

Energy prices,substitution, and optimal borrowing in the short run: An analysis of adjustment in oil importing developing countries

The paper discusses optimal short-term borrowing in response to an increase in the price of imported inputs. The rationale for borrowing lies in the increase in substitution possibilities in production (between imported and domestic inputs) and in consumption (between traded and non-traded goods) as the economy adjusts its structure to the new prices. A typology of LDCs and the oil price increases in the 70's are used to illustrate the results of the model, which are compared with the actual increase in borrowing during the period.
