Testing the theory of PPP for emerging market economies that practice flexible exchange rate regimes

This study aims to test the long-run validity of purchasing power parity by using Fourier quantile unit root and Fourier cointegration analyses for 12 emerging market economies that practice a flexible exchange rate regime. With the Fourier approach, structural breaks are modelled as a gradual and smooth process. Fourier quantile unit root test results show that real exchange rate series are stationary for Colombia, India, Philippines, Poland, South Africa, and Turkey. On the other hand, Fourier cointegration test results reveal that purchasing power parity is valid for Brazil, Colombia, India, Mexico, South Africa, Thailand, and Turkey.     

Slack and the performance of state-owned enterprises

Organizational slack has been recognized as critical to firm performance, although its impact is not always positive. Slack may be used to fuel innovation or alternatively excess resources may be squandered on pet projects. However, most research on slack is rooted in studying private firms in developed economies, especially the United States. Whether prior research on organizational slack can readily inform our understanding of state-owned enterprises’ (SOEs) behavior is questionable since SOEs prioritize goals such as social welfare and full employment differently than do the privately owned enterprises (POEs). The differences between SOEs and POEs influence their sources and use of slack due to the nature of their ownership, budget constraints, and agency relations. To bring insight to this issue we develop an institutional change lifecycle model to study the relationship between slack and the economic and social aspects of SOE performance.     

连续性跟踪测试中创新的数据采集方法:处理市场研究准则与市场实况之间的必然冲突

跟踪测试的“3C”：一致性，一致性，和一致性 跟踪测试是指在多于一个时间点上，在相同的抽样人群内收集同类信息的市场研究项目。跟踪测试所得到的数据可用于评估市场的变化，这对于那些快速变化的事物尤显重要——例如厂告宣传——又或是那些微小变化都会影响业务表现的领域——例如客户满意度。为了确保跟踪测试提取出了市场上发生的真实变化，理论上每次测试都需按照相同的方式执行。例如，每次都问相同的题目。按照相同的顺序提问，访问同类型的被访，由同一组访问员进行数据采集等等。其中至关重要的是测试所使用的访问方法。通常在开始一个跟踪测试的时候有很多方法可供选择——电话访问、面访、入户访问（这个方法在中国仍被很普遍地使用）或定点访问等。     

Venture Capitalists, Syndication and Governance in Initial Public Offerings

This paper examines the development of effective boards in venture capital (VC)-backed initial public offerings. It argues that VC-backed IPOs suffer from two sets of agency costs which are related to principal–agent and principal–principal relationships between the founders and members of the VC syndicate. Using a unique sample of 293 entrepreneurial IPOs in the UK it shows that VC syndicates invest in relatively more risky firms. VC-backed IPOs have more independent boards than IPOs with no VC involvement, with board independence being higher in syndicated VC-backed firms. These results are consistent with assumption that these governance factors are used to mitigate agency costs associated with VC involvement in IPO firms. We also find that in syndicated IPOs there is a higher equity presence of passive private equity firms investing alongside VC firms.     

Communicating nutrition information at the point of purchase: An eye‐tracking study of shoppers at two grocery stores in the United States

Providing nutrition information at the point of purchase is one approach that can be used to help consumers adopt and maintain a healthy diet. Previous research has examined consumer self‐reported notice and use of the information as well as how the design of the information affects its attention and use in a laboratory environment using eye‐tracking methodology. This study advances the literature by applying eye‐tracking methodology to explore consumer visual and choice behavior in a real shopping environment, and by recognizing that nutrition information competes with other visual stimuli in the store and consumers are vulnerable to a “limited attention span” for nutrition information in a shopping setting. Data came from a cross‐sectional survey conducted in two grocery stores in the United States in July 2014 with a convenience sample of 60 grocery shoppers while they were selecting and buying items from one of three product categories (ready‐to‐eat cereal, snacks, and soup). The study finds that point‐of‐purchase nutrition information faced strong competition for participants’ attention from other visual elements in a real shopping environment and the attention is dominated by nonnutrition elements, particularly brand/product name, product imagery, and product pricing. Nutrition‐related information, on the other hand, received much less attention, with claims and front‐of‐package nutrition symbols seen by more participants than the Nutrition Facts label. The study suggests that to more effectively enable nutrition information to “catch the eyes” of shoppers at the point of purchase, increasing consumer exposure to the information and enhancing shopper education may merit further investigation.     

Where is the opportunity in opportunity zones?

In December 2017, the U.S. Congress passed into law the Opportunity Zone (OZ) program. As an OZ, designated low-income census tracts provide considerable tax breaks to property investors, intending to attract investments and spur economic growth. As the success of the program is dependent on investors' responses, we analyze market reactions in a difference-in-differences framework. We identify two potential effects on property markets: tax breaks for investors and expected land value appreciation. Our results show that tax breaks are priced efficiently. Qualified properties increase by 7–20% in price, while vacant land increase up to 37%. In contrast, we find limited signs of expected land value appreciation.     

Proxy variable estimation of productivity and efficiency

We model productivity and inefficiency jointly, instead of modeling and estimating either only productivity or only inefficiency with many variable and quasi-fixed inputs. In the first model, we use a multi-step procedure. We use the proxy variable method based on the first-order condition (FOC) of expected profit maximization with respect to the single variable input to take care of the endogeneity problem arising from both productivity and inefficiency. To separate mean inefficiency from mean productivity we assume them nonparametric functions of different sets of exogenous variables. In the second model, we consider a novel system consisting of the production function and the FOCs of expected profit maximization for the multiple variable inputs. Distributional assumptions are made on all the random errors associated with the production function, the FOCs, productivity, and inefficiency functions in the second model. We use the Colombian food manufacturing data as an application of our model.     

IMAGINING A DECOLONIZED CITY IN AND FROM AOTEAROA NEW ZEALAND

Imagining decolonized cities creates space to explore how urban places could strip away colonial dominance and restore the ability of Indigenous people to live, know and be. In this essay, we describe one attempt to create such space. While working in Porirua in Aotearoa New Zealand, we ran an urban design competition, hosted workshops with young people and held a symposium. Through all three phases we drew on utopian thinking to imagine beyond the current constraints of urban form in Aotearoa New Zealand to consider how cities might reflect the diverse realities of Māori. While this approach is an attempt at generating hopeful geographies, it also sat in tension with (post)colonial realities, such as racist attempts by white people to claim Indigeneity, and the ongoing need for land to be returned to Indigenous people. We argue that envisioning how cities might be decolonized is useful and needs to be rooted in the particular politics of place, but this imagining needs to be paired with action to confront persistent colonialism.
