Tax Setting in a Federal System: The Case of Personal Income Taxation in Canada

In a decentralised tax system, the effects of tax policies enacted by one government are not confined to its own jurisdiction. First, if both the regional and the federal levels of government co-occupy the same fields of taxation, tax rate increases by one layer of government will reduce taxes collected by the other. Second, if the tax base is mobile, tax rate increases by one regional government will raise the amount of taxes collected by other regional governments. These sources of fiscal interdependence are called in the literature vertical and horizontal tax externalities, respectively. Third, as Smart (1998) shows, if equalisation transfers are present, an increase in the standard equalisation tax rate provides incentives to raise taxes to the receiving provinces. A way to check the empirical relevance of these hypotheses is to test for the existence of interactions between the regional tax rate, on the one hand, and the federal tax rate, the tax rate set by competing regions, and the standard equalisation tax rate, on the other hand. Following this approach, this paper estimates provincial tax setting functions with data on Canadian personal income taxation for the period 1982–1996. We find a significant positive response of provincial tax rates to changes in the federal income tax rate, the tax rates of competing provinces, and the standard equalisation rate (only for receiving provinces). We also find that the reaction to horizontal competition is stronger in the provinces that do not receive equalisation transfers.

Competition regimes and air transport costs: The effects of open skies agreements

The relevance of transport costs has increased as liberalization continues to reduce artificial barriers to trade. Is it worthwhile to implement policies designed to increase competition in transport markets? Focusing on air transport, this paper quantifies the effects of liberalization of air cargo markets on transport costs. Between 1990 and 2003, the United States implemented a series of Open Skies Agreements, providing a unique opportunity to assess the effect that a change in the competition regime has on prices. In our sample, Open Skies Agreements reduce air transport costs by 9% and increase by 7% the share of imports arriving by air. Those results hold for developed and upper-middle-income developing countries but for lower-middle-income and low-income developing countries Open Skies Agreements do not reduce air transport costs.     

Maximal Domain of Preferences in the Division Problem

The division problem consists of allocating an amount of a perfectly divisible good among a group of n agents. Sprumont (1991) showed that if agents have single-peaked preferences over their shares, then the uniform allocation rule is the unique strategy-proof, efficient, and anonymous rule. We identify the maximal set of preferences, containing the set of single-peaked preferences, under which there exists at least one rule satisfying the properties of strategy-proofness, efficiency, and strong symmetry. In addition, we show that our characterization implies a slightly weaker version of Ching and Serizawa's (1998) result. Journal of Economic Literature Classification Numbers: D71, D78, D63.     

Online sales, Internet use, file sharing, and the decline of retail music specialty stores

This paper uses phonebook records of music retailers in the United States for the years 1998 and 2002 to examine how Internet use, file sharing, and online sales of records have affected the entry and exit of brick and mortar music specialty retailers. By merging music store information with data on Internet activity and broadband connectedness at the metropolitan statistical area (MSA) level, with the number of broadband providers at the zip code level, and with a database of the location of universities, I analyze how online purchases, broadband, and Internet use affected the survival probability and the change in the number of music stores between 1998 and 2002. I further study whether the number of employees and chain membership affected the survival probability. I find that broadband connectedness increased the death rate of brick and mortar music stores and reduced their number. I also find that the presence of a university led to a reduction in the number of music specialty stores in the zip code.     

Sustainable finance: The role of savings and credit cooperatives in Ecuador

The current world situation leads us to consider that sustainable development needs to be a global priority to ensure the future of the planet and improve the quality of life. There is a need for sustainable finance to support this. Savings and credit cooperatives could help to achieve this impact as they serve the microfinance and microlending market. They facilitate the financial inclusion of the most vulnerable people, most of whom live in rural areas and are members of organizations, such as agricultural cooperatives and associations. Previous studies have focused exclusively on overall profitability, so this paper contributes to extending the literature by analyzing the whole population of savings and credit cooperatives in Ecuador (510 institutions), focusing on their profitability in two ways: the overall profitability necessary for the viability of the business and, in addition, the microcredit portfolio profitability, as a specific measure of its contribution to sustainability and social value creation. Another novelty is that the analysis has been carried out using several machine learning techniques for the wider generalization of the results. These show that size is the most relevant variable for predicting the ROE and that the microcredit portfolio profitability is conditioned by the credit variables.     

Welfare and sectoral productivity shifts in a small open economy with imported agricultural inputs: The case of Sub-Saharan Africa

This paper studies the impact of sectoral productivity growth on welfare in Sub-Saharan Africa. Using the analytical framework of a DSGE model, the main finding is that, for the estimated values of structural parameters, the allocation of scarce resources to the tradable agricultural sector for boosting productivity leads to a greater increase in overall welfare than would be the case if they were allocated to the non-traded goods sector.

     

Trade in the shadow of power: Japanese industrial exports in the interwar years

During the interwar years, Japanese industrialization accelerated alongside the expansion of industrial exports to regional markets. Trade blocs in the interwar years were used as an instrument of imperial power to foster exports and as a substitute for productivity to encourage industrial production. The historiography on Japanese industrialization in the interwar years describes heavy industries’ interests in obtaining access to wider markets to increase economies of scale and reduce unit costs. However, this literature provides no quantitative evidence that proves the success of those mechanisms in expanding exports. In this article we scrutinize how Japan—a relatively poor country—used colonial as well as informal power interventions to expand regional markets for its exports, especially for the most intensive human capital sector of the industrializing economy. Our results show that Japanese exports in 1938 would have been around one-third smaller had no empire ever existed, which indicates an outstanding effect of empire in the international context.     

Group identification with (incomplete) preferences

We consider the problem of identifying members of a group based on individual opinions. Since agents do not have preferences in the model, properties of rules that concern preferences (e.g., strategy‐proofness and efficiency) have not been studied in the literature. We fill this gap by working with a class of incomplete preferences derived directly from opinions. Our main result characterizes a new family of group identification rules, called voting‐by‐equitable‐committees rules, using two well‐known properties: strategy‐proofness and equal treatment of equals. Our family contains as a special case the consent rules (Samet & Schmeidler. J. Econ. Theory, 110 (2003), pp. 213–233), which are symmetric and embody various degrees of liberalism and democracy; and it also includes dictatorial and oligarchic rules that value agents’ opinions differently. In the presence of strategy‐proofness, efficiency turns out to be equivalent to non‐degeneracy (i.e., any agent may potentially be included or excluded from the group). This implies that a rule satisfies strategy‐proofness, efficiency, and equal treatment of equals if, and only if, it is a non‐degenerate voting‐by‐equitable‐committees rule.
