融入策划思想的规划思路探讨——以同里景区控制性规划为例

经济全球化的大背景下,投资体制、资源和利益分配体制都快速的摆脱原来计划经济的轨道,越来越受市场规律的引导和制约,在投资渠道越来越多元的今天,建设程序也有了很大的不同,这些变革都要求我们在规划过程中打破原来以物质空间规划为重心的规划方式,全方位的革新规划的技术方法和思路．为了在规划过程中真正理解规划实施的最重要因素“市场需求”,我们尝试在同里景区控制性规划中借鉴市场营销等方面的理论,引入市场策划的思想,力求让规划成果兼顾投资方利益以及公共利益,使之在实施过程中具有更高的可行性和可操作性。     

利益与风险偏好差异:上市公司委托理财行为及对策的经济学分析

通过对上市公司决策主体分企业和个人两个层次的分析发现由于企业的内部控制者在委托理财行为中可以获得较大收益却无需承担失败的损失,加上长期的执法不力,他们与企业存在利益与风险偏好上的差异,从而解释了那么多的上市公司对风险很大的委托理财趋之若鹜的原因.要重构上市公司委托理财行为中的"共有信念",需要加大执法力度,且实现一定约束下的法律成本在用于制定新的法规和执行已有法规之间的优化配置;此外,通过提高企业控制人的分成比例,设立企业控制人的个人保证账户也可以减少企业控制人在委托理财中的违法违规行为.     

General equilibrium impact of an energy-saving policy in the public sector

We analyse a disregarded environmental policy instrument: a switch in government expenditure away from energy (or other natural resources) and toward a composite good which includes energy-saving expenditure. We first develop two variants of an analytical general equilibrium model. A composite good is produced with constant returns to scale, and energy is imported or produced domestically with diminishing returns, yielding a differential rent to its owners. The government purchases energy and composite goods from private firms. Such a policy unambiguously increases employment. It also raises private consumption and welfare under two conditions: (i) it is not too costly and (ii) the initial share of the resource is smaller in public spending than in private consumption, or the difference is small enough. We then run numerically a model featuring both importation and domestic production of energy (oil, gas and electricity), for the OECD as a whole. Simulations show that employment, welfare and private consumption rise. We provide magnitudes for different parameter values. Earlier versions of this paper have benefited from conference participants at the European Council for an Energy-Efficient Economy, International Society for Ecological Economics World Congress, CIRED seminar and EUREQua environmental economics seminar.

城市新就业职工住房保障问题实证研究——基于合肥市新就业职工的调查

调查表明,50％多的新就业职工住房困难.由于收入较低,新就业职工住房支付能力严重不足,30％多的新就业职工家庭缺乏租房支付能力;超过70％的新就业职工家庭缺乏购房支付能力.所以,要尽快将新就业职工纳入住房保障范围.首先,提高新就业职工收入水平,遏制住房价格过快上涨;其次,多渠道筹集住房保障资金;第三,积极创新相关配套政策,完善公共租赁住房准入和退出机制;第四,适时推出限价商品住房,利用优惠信贷政策,提高新就业职工住房支付能力.

Quote inefficiency in options markets

In an arbitrage-free economy with non-zero bid-ask spreads the existence of payoffs whose price is lower than the price of a dominated payoff cannot be discarded in general. However, when the former price corresponds to trivial portfolios which involve buying or selling one unit of the basis assets, its presence, although not an arbitrage, is a severe market anomaly which we refer to as an inefficient quote. In an empirical study, we report evidence that indicates that in options markets both the frequency and the magnitude of these anomalies are substantial and we document puzzling patterns in their behavior.     

Institutional failure or market failure?

We investigate the effect of the power of creditors, property rights protection, and institutional quality, on bank profits using a panel of 498 banks from 46 countries. Results show that better institutions and stronger property rights protection reduce bank profits, while stronger power of creditors drives up bank profits significantly. Results imply that better institutions and enhanced property rights protection lead to greater flow of credit allowing firms and investors to undertake more profitable ventures. By extension, stronger creditor rights erect steeper barriers to external finance for firms and investors. National indicators of economic freedoms may be more important to lowering the spread than strict creditor rights. Seemingly, credit markets fail when economic institutions fail or when governments intervene into these markets in ways that impede the safety and soundness of financial transactions and private contracting.     

《行政复议法》实施以来的成就、不足与展望

《行政复议法》的颁布与施行至今已有十余年,在这十多年的时间里,行政复议制度有效发挥了化解行政争议、保护行政相对人的合法权益以及保障和监督行政机关依法行政等功能,但与此同时,行政复议制度还有诸多不足。当前,对《行政复议法》实施以来所取得成就的回顾以及对其不足的反思,是完善我国行政复议制度的一项重要任务,也是我国行政复议制度取得更大成就的必由之路。     

Females' perspectives on tourism's impact and their employment in the sector: The case of Petra,Jordan.

This study aims to explore the trend towards gender equality in the tourism sector of the Petra region, Jordan. To do so, a mixed methods design including a questionnaire and in-depth interviews was employed for female residents of rural and urban areas in the region. The results show that women do not have favourable view of tourism's economic impacts and that several barriers exist to their employment in the tourism sector. The findings' implications and future studies are addressed.     

Understanding the impact of COVID-19 intervention policies on the hospitality labor market

Using new high-frequency data that covers a representative sample of small businesses in the United States, this study investigates the effects of the COVID-19 pandemic and the resulting state policies on the hospitality industry. First, business closure policies are associated with a 20–30% reduction of non-salaried workers in the food/drink and leisure/entertainment sectors during March-April of 2020. Second, business reopening policies play a statistically significant role in slowly reviving the labor market. Third, considerable differences exist in the impact of policies on the labor market by state. Fourth, the rise of new COVID-19 cases on a daily basis is associated with the continued deterioration of the labor market. Lastly, managerial, practical, and economic implications are described.
