Understanding the drivers of Urban Development Agreements with the rough set approach and robust decision rules

The rise of neoliberalism in the context of urban development has encouraged cooperation between public and private parties. This cooperation is structured by contracts, generally called Urban Development Agreements (UDAs). Being part of the urban regeneration strategies, UDAs aim at achieving durable improvements of abandoned areas, namely brownfields, according to the sustainability principles. Thus, within the negotiation between private developers and public administrations, multiple and conflicting instances have to be faced case by case. Despite the uniqueness of each UDA, it is possible to define a set of pertinent characteristics that play a crucial role in determining the fairness and appropriateness of the public-private partnership. Given this context, we propose a novel variant of the Dominance Rough Set Approach (DRSA) for i) exploring the relationship between condition attributes or criteria and effects of urban development processes and for ii) supporting negotiations according to the detection of a set of relevant features. Specifically, DRSA is applied on a sample of UDAs recently concluded in the Lombardy Region (Northern Italy), and then tested on a sample of other UDAs under the negotiation phase. The analysis involves five dimensions represented by attributes and criteria related to urban, institutional, negotiation, development and economic contexts. The inferred decision rules provide useful knowledge for supporting complex decision processes such as the allocation of costs and benefits within UDAs.     

泰勒规则:一个新的解释

泰勒规则在20世纪90年代以来为美联储等央行所采用,也为众多央行所关注,但该规则在操作中存在诸多不确定性。由于货币政策最终目标物价稳定的强制性,政策目标利率具有一定的相机抉择性,泰勒规则其实是规则和相机抉择的结合。考虑到利率平滑的机会成本较小,泰勒规则发挥作用的关键在于货币当局与公众建立良好的交流机制。货币当局应配合利率调整实行联合或单独交流战略,管理预期,影响市场行为。     

A test of the Investor's Daily stock ranking system

This paper examines the profitability of trading strategies derived from stock rankings published in Investor's Business Daily. The best system provides market-adjusted abnormal monthly returns of 1.81% from buying S&P 500 stocks, and a 3.18% abnormal return on an arbitrage portfolio. Stocks selected for trading have above average volatility, but a portion of abnormal return may be a reward for identifying stocks with short-run sustainable price momentum. Results seem indicative of market inefficiency, but the phenomena may be temporary since abnormal returns are lower during the second half of the data set.     

Generating currency trading rules from the term structure of forward foreign exchange premia

The quality of an exchange rate forecasting model has typically been judged relative to a random-walk in terms of out-of-sample forecast errors. The difficulty of outperforming this benchmark is well documented, although Clarida and Taylor have demonstrated how the random walk can be beaten in this metric by exploiting information embedded within the term structure of forward exchange rate premia. But this achievement does not guarantee success within an investment context. We therefore assess whether the Clarida-Taylor framework can be used to generate significant trading profits in combination with an acceptable degree of risk in a realistic investment portfolio context.

Cognitive Rules, Institutions, and Competition

Rules exert an important influence on rational individual behaviour. In economic analyses, two different types of rules occur that both induce rule-following behaviour. However, they are rarely distinguished. The differentiation of institutions (as interpersonal rules) and cognitive rules (as intrapersonal rules) allows for a clarification of substantial differences between the two types of rules, for example, concerning the incorporated knowledge and rule-persistence. Furthermore, the analysis of the interrelation of the two types of rules offers fruitful insights that still are not much explored in economics. The important dimensions to be considered are rule-harmony that stabilises institutional arrangements, and rule-conflict that induces pressure on persistent institutions. In this context, competition can be seen as a medium of interaction that allows individual agents to learn both about the behaviour of interacting agents and the nature and effects of the institutional framework. The integration of competition - as the core concept of economics - into the interplay of institutions and cognitive rules explores a missing point within the analysis of the economics of rules.     

Efficient Contracting and Fair Play in a Simple Principal-Agent Experiment

We study behavior within a simple principal-agent experiment. Our design allows for a large class of linear contracts. Principals can offer any feasible combination of (negative) fixed wages and incentives in the form of return sharing. This great contractual flexibility allows us to study incentive compatibility simultaneously with issues of 'fair sharing' and reciprocity, which were previously found to be important. We find a high degree of incentive-compatible behavior, but also 'fair sharing' and reciprocity. In contrast to other incentive devices studied in the literature, the incentives are 'reciprocity-compatible'. Principals recognize the agency problem and react accordingly.     

试论国际贸易行政案件法律适用问题

入世带给司法机关的严峻挑战是 ,如何将WTO法律在国内实施以解决与WTO有关的国际贸易争端。在WTO法律国内适用问题上各成员国空前统一 ,采用了间接适用原则 ,对此我国也不例外。我国在坚持间接适用WTO法律的同时也承诺了特定情况下的直接适用 ,能否直接适用关键要看是否有利于保护本国利益。     

论国际商事仲裁员披露义务规则

国际商事仲裁是跨国交易者越来越普遍地采用的争议解决手段。尽管国际商事仲裁员可以由跨国交易的当事人协议选定，遵循披露义务规则却仍然是绝大多数国家和国际商事仲裁机构的强制性要求。对违背该义务的行为，国际商事仲裁法制非常健全的国家或地区为当事人提供了很周全的救济手段。目前，我国依然没有建立起有效的国际商事仲裁员披露义务及其违反的救济规则，我国应当借鉴发达国家或地区的经验，通过修仃《仲裁法》的相关条款予以完善。
