Indirect Taxation in Greece: Evaluation and Possible Reform

The paper assesses the distributional and efficiency/disincentive aspects of the Greek indirect tax system, which provides 60% of total tax revenue. The marginal welfare costs of broad commodity groups were computed to identify welfare-improving directions of reform. The disincentive effects were estimated from marginal indirect tax rates using Household Expenditure Survey data. The indirect tax structure is shown to be unnecessarily complicated and inefficient, without achieving any redistributive goals. The UK indirect tax structure was shown to be simpler, more equitable and more efficient to implement and administer when simulated on Greek consumers.     

The impact of regional competition on the health care industry

We investigate factors that determine firm markups by employing data on prices and quantities of various medical procedures at major hospitals in the United States. We focus on the impact of hospital quality, rival competition and the number of medical procedures upon the health care demand. Our analysis covers health-care markets across the United States with the market definition based upon the hospital referral regions. Our findings highlight potential implications of the relationship between hospital markups and market structure.     

STRATEGIC BIDDING AND CONTRACT RENEGOTIATION

When firms bid in procurement auctions, they take into account the likelihood of future contract renegotiations. If they anticipate that certain input quantities will change ex post, they have an incentive to strategically skew their itemized bids, thereby increasing profits for themselves and costs for the procuring agency. We develop and estimate a structural model of strategic bidding using a data set of road construction projects in Vermont. We find that bidding strategies lead to increased markups for renegotiated items and reduced markups for nonrenegotiated items, results consistent with bid‐skewing.     

Planning Gentrification and the ‘Absent’ State in Athens

In times of austerity, gentrification is promoted as a prime investment opportunity capable of reviving stagnating local economies. In Athens, pro‐gentrification policies (using English slogans like ‘Re‐launch Athens’ and ‘Re‐activate Athens’) have become increasingly defined in their targeting of specific areas. Moreover, planning in Greece is characterized by spontaneity, fragmentation and tolerance of speculation, specifically favouring the gentrification process. In many cases, the state's ‘absence’ after promulgation of regeneration projects acts as a clear strategy for inner‐city gentrification. After discussing the emergent relations between state policies on urban intervention and gentrification in the post‐crash era, this article will focus on the peculiarities of the Greek planning system and how these have led to the gentrification of an inner‐city area called Metaxourgio.     

Efficient Bayesian Mechanisms for Collective Goods: Is a Deficit Inevitable?

This paper considers efficient Bayesian mechanisms for the provision of collective goods. We study the impact of excludability and the nature of externalities exhibited by collective goods upon incentives. We demonstrate that if a good is rivalrous only excludability of benefits allows a designer to restrict each agent's payoff enough to achieve efficiency in the limit. The more exclusive a rivalrous good, the smaller is the financial deficit in the mechanism relative to the size of the surplus of the economic activity. In contrast, if a good exhibits positive externalities, excludability is no longer necessary to achieve efficiency in provision.     

Informed trading around merger and acquisition announcements: Evidence from the UK equity and options markets

This paper offers new evidence on informed trading around merger and acquisition announcements from the UK equity and options market. The analysis suggests that in about 25–33% of events there is abnormal option trading volume during the month that precedes the announcement. Such evidence is found in both call and put option volumes, is robust to different “estimation” and “event window” lengths, to different sub‐samples, and to liquidity considerations. These results support the argument that informed investors will transact in both the options and the stock market, and are comparable to results reported by the FSA in the cash market. © 2010 Wiley Periodicals, Inc.

The role of organizational cultures in information‐systems security management: A goal‐setting perspective

The aim of this research is to investigate the role of strong organizational cultures in setting information‐systems security goals. In doing so, we explore and discuss the concept of culture within three financial organizations with different social and organizational structures, and seek to demonstrate the importance of having a cohesive culture in efficiently setting information‐security goals. The relationship between goal setting, culture strength, and performance is also discussed, as there have been studies that indirectly indicate that such a relationship may exist. The contribution of this work to interpretive information‐systems research consists of its study of culture and goal setting in a security‐management context, and its grounding within an interpretive epistemology. In addition, this research promotes an interdisciplinary and interorganizational theory to foster dialogue that transcends industry‐specific contexts and explores different organizational practices that can improve leadership's role in human life.
