世界遗产视野中的中国传统工业遗产

我国有着十分丰富的传统工业遗产资源,在许多古代文献与现代研究已有著述。在已经公布的六批总计2358项全国重点文物保护单位中,共有工业遗产171项,其中古代传统工业遗产计为14类149项,体现出我国政府对传统工业遗产的保护力度。但在我国(物质)文化遗产暨工业遗产研究领域,从世界遗产的视野对传统工业遗产的研究,与国际同一研究领域相比,还存在着较大的差距。文章运用地理学的观念与方法,阐述了中国传统工业遗产研究的背景与意义、保护现状以及研究展望,为今后的工业遗产保护提供参考。     

Islamist terrorism and the status of women

We investigate the effect of Islamist terrorist activity on women's legal position in society, using data for 171 countries between 1970 and 2016. To identify causal effects, we exploit the prevalence of Islamist terrorism in neighboring countries as an exogenous source of variation, arguing that regional terrorism affects local terrorism through contagion effects. We show that increased activity by Islamist terrorist groups is linked to lower legal status of women. By contrast, we find that neither Islam per se nor other types of terrorism have comparable effects. This reinforces the notion that Islamist terrorism is singularly interested and effective in weakening women's rights. Our results are consistent with a rational-economic model of terrorism, where Islamist terrorists purposefully use violence to maximize political utility, while governments make concessions that constrain the role of women because the costs of compliance are lower than the harm from continued Islamist terrorism.     

Multiplicity in general financial equilibrium with portfolio constraints

This paper explores the role of portfolio constraints in generating multiplicity of equilibrium. We present a simple financial market economy with two goods and two households, households who face constraints on their ability to take unbounded positions in risky stocks. Absent such constraints, equilibrium allocation is unique and is Pareto efficient. With one portfolio constraint in place, the efficient equilibrium is still possible; however, additional inefficient equilibria in which the constraint is binding may emerge. We show further that with portfolio constraints cum incomplete markets, there may be a continuum of equilibria; adding incomplete markets may lead to real indeterminacy.     

The “Business Climate” and Economic Inequality

“Business climate indexes” characterize state economic policies, and are often used to try to influence economic policy debate. However, they are also useful in research as summaries of a large number of state policies that cannot be studied simultaneously. Prior research found that business climate indexes focused on productivity and quality of life do not predict economic growth, while indexes emphasizing taxes and costs of doing business indicate that low‐tax, low‐cost states have faster growth of employment, wages, and output. In this paper, we study the relationship between these two categories of business climate indexes and the promotion of equality or inequality. We do not find that the productivity/quality‐of‐life indexes predict more equitable outcomes, although some of the policies underlying them suggest they might. We do find, however, that the same tax‐and‐cost‐related indexes that are associated with higher economic growth are also associated with increases in inequality.     

Non‐linear geographics and the economics of transition and democratization1

The purpose of this study is to analyse the effects of geography on the transition process in authoritarian political regimes, and to investigate the nature of the links between political change, economic reforms and geographical location. A simple model of transition and democratization is presented wherein we show that the effectiveness of repression by the incumbent elite is a negative function of the distance to the ‘free world’. In consequence, geography has conflicting effects on shifts in political power. This article provides a rationale for the counterintuitive fact that the first authoritarian country to start a transition process towards democratization is not necessarily the one nearest to the free world.     

A note on the incompatibility of strategy-proofness and Pareto-optimality in quasi-linear settings with public budgets

We show that any deterministic mechanism, for allocating identical items that are complements to budget-constrained bidders, cannot simultaneously satisfy individual-rationality, strategy-proofness, Pareto-efficiency, and no-positive-transfers. This holds even for two bidders, two items, and commonly-known budgets, and generalizes to richer settings.     

Optimal Retirement with Increasing Longevity

We develop an optimizing life‐cycle model of retirement with perfect capital markets. We show that longer healthy life expectancy usually leads to later retirement, but with an elasticity less than unity. We calibrate our model using data from the US and find that, over the last century, the effect of rising incomes, which promote early retirement, has dominated the effect of rising lifespans. Our model predicts continuing declines in the optimal retirement age, despite rising life expectancy, provided the rate of real wage growth remains as high as in the last century.     

Second thoughts on free riding

We use the strategy method to classify subjects into cooperator types in a large-scale online Public Goods Game and find that free riders spend more time on making their decisions than conditional cooperators and other cooperator types. This result is robust to reversing the framing of the game and is not driven by cognitive ability, confusion, or natural swiftness in responding. Our results suggest that conditional cooperation serves as a norm and that free riders need time to resolve a moral dilemma.     

纳税信用评级结果披露与研发投入

以纳税信用评级披露作为一个天然外生冲击,并基于2013—2016年1214家A股上市公司的微观数据构造准自然实验,使用双重差分法系统评估纳税信用评级结果披露对上市公司研发投入的影响。结果发现:纳税信用评级结果披露显著增加了上市公司的研发投入。基于PSM-DID方法的估计结果与上述结论无明显差异。稳健性检验也表明上述结论的正确性。机制检验表明,纳税信用评级结果披露通过降低企业的融资约束,进而促进企业增加研发投入。此外,分样本回归发现纳税信用评级结果披露只能对中小型企业和民营企业的研发投入产生促进作用。     

Credit constraints and productivity of SMEs: Evidence from Canada

To what extent firms are constrained by external credit is usually unobserved in commonly used firm-level data. We use a survey of financing among Canadian small and medium-sized enterprises to measure the likelihood of a firm being constrained by credit. We find that firm size, current debt-to-asset ratio and cash flow are robust indicators of being financially constrained, while long-term debt to asset ratio is not a significant indicator of credit constraints. We then estimate the firm-level total factor productivity, taking into account the measured credit constraints. Omitting credit constraints leads to an upward bias of productivity estimates, by 4 percent. In addition, we find no strong evidence that suggests credit constraints lead to slower productivity growth. Finally, we confirm that both investment and employment growth are negatively affected by the measured credit constraints.
