Joint Quantity/Quality Management of Groundwater

Economic literature on groundwater managementhas traditionally been split into two areas: there are papers that evaluate different schemes of dynamicaquifer management, considering that pumping costs vary with stock but ignoring water quality. On the other hand, there are papers that considercontamination problems caused by specificpollutants. This paper presents two alternative models for joint quantity-quality management, and it shows that existing models are in fact special cases of these. The framework isdynamic and considers both the stock of waterquantity and a stock measure of water quality. Optimal taxes are derived, and shown to be different from those in existing quantity-only or quality-only models. Implementationproblems are briefly discussed.     

Click Here for Internet Insight: Advances in Clickstream Data Analysis in Marketing

Clickstream data are defined as the electronic record of Internet usage collected by Web servers or third-party services. The authors discuss the nature of clickstream data, noting key strengths and limitations of these data for research in marketing. The paper reviews major developments from the analysis of these data, covering advances in understanding (1) browsing and site usage behavior on the Internet, (2) the Internet's role and efficacy as a new medium for advertising and persuasion, and (3) shopping behavior on the Internet (i.e., electronic commerce). The authors outline opportunities for new research and highlight several emerging areas likely to grow in future importance. Inherent limitations of clickstream data for understanding and predicting the behavior of Internet users or researching marketing phenomena are also discussed.

Taking services to foreign markets: A taxonomy of Brazilian service firms

This study develops a taxonomy of international service firms from an emerging market, Brazil, and assesses whether there are significant differences in international performance between the groups. After an extensive literature review, a survey was carried out with a sample of international service firms located in an emerging economy, Brazil. Using as a departure point two theoretical perspectives, the internationalization process theory and industrial organization theory, in addition to service dimensions extracted from the empirical service management literature, the study identifies four groups—large traditionals, generalist neophytes, solitary traditionals, and daring differentiators—based on firm characteristics, international services delivered, internationalization process characteristics, and international strategies adopted. The findings suggest that there are significant differences in performance between the groups.     

NINA/LILA debtors under the Portuguese Insolvency Act: A hidden problem in plain sight?

No income, no assets (NINA) and low income, low assets (LILA) debtors are a non‐negligible part of the increasingly ‘financialized’ market economy. Falling outside the financial market or accessing it through low quality financial products, NINA/LILA debtors appear to be under prioritized by both legal and judicial regimes and public policies. Focusing on the legal and judicial dimension, and taking as an illustration the Portuguese context, we discuss how preinsolvency and insolvency solutions still remain ill‐adjusted for such cases. In spite the existence of some legal provisions aiming at fostering access to law and courts regardless individuals' financial conditions, they do not perform very well with insolvent debtors lacking a regular income. Addicionally, there are non‐legal barriers that prevent those with less economic means to fight properly for their social and economic rights.     

Comparing two territory partitions in districting problems: Indices and practical issues

Planning as part of public sector decision-making situations is an activity of critical importance, with direct relevance for urban planners. The ramifications of such decisions generally have significant effect on peoples’ lives. The current paper deals with the comparison between territorial maps in the context of districting problems with a strong socio-economic component. The theoretical problem involves the comparison of two partitions in a connected, undirected, and planar graph. In considering this problem, we introduce three new indices to compare territory partitions: compatibility, inclusion, and distance, all of which have importance for real-world planning situations. Numerical experiments of these indices were carried out for the communes network in (Iˆle de France), France.     

Taxation without commitment

This paper considers a Ramsey model of linear capital and labor income taxation in which a benevolent government cannot commit ex-ante to a sequence of policies for the future. In this setup, if the government is forced to keep budget balance in every period, then it may not be able to sustain zero capital taxes in the long run, as shown in Benhabib and Rustichini (J Econ Theory 77:231–259, 1997) and Phelan and Stachetti (Econometrica 69:1491–1518, 2001). However, (Dominguez in J Econ Theory 135:159–170, 2007) shows that if the government is allowed to borrow and lend to households, the optimal capital income tax still converges to zero in the long run, as long as the value of defaulting is independent of the level of government debt. This paper provides a game theoretic setup with government debt where the value of the worst equilibrium only depends on the initial level of capital and can be determined in advance. This implies that under our assumptions the best sustainable equilibrium has zero capital taxes in the long run, even in the absence of government commitment.     

Bank merger and acquisitions activity in the EU: much ado about nothing?

This paper investigates the patterns of consolidation within the European banking industry and examines the efficiency of the banks involved in the merger and acquisitions (M&A) activity to determine whether their performance improved as a result of M&A decisions. The performance of these banks is compared with that of other large banks, which have chosen alternative routes of development. The period covered is 1998 to 2004. The findings suggest that banks involved in M&A activity are more efficient after the M&A or when compared with other large banks. Country-specific characteristics appear to play an important role in explaining the results.
