Extreme risk spillovers between crude palm oil prices and exchange rates

This study is the first attempt to examine the extreme risk spillovers between Malaysian crude palm oil (CPO) and foreign exchange currencies of the three largest CPO importers: India, the European Union and China throughout the global financial crisis. Using daily data of three currencies, CPO spot and futures from 2000 to 2018, our results show: First, before the crisis, the unexpected change in foreign exchange rates is the primary driver of risk spillover to the CPO market. Second, during the crisis, the extreme movement of CPO spot returns is dominant in the Malaysian exchange rates relative to the euro. Third, after the crisis, the spillover flows from the CPO market to the foreign exchange market. Overall, our findings show the importance of CPO pricing dynamics in mitigating foreign exchange risk over the crisis period. This paper contributes to the extant literature by recognizing the effect of risk spillover on the targeted foreign exchange rate for portfolio allocation.     

Time-varying inter-urban housing price spillovers in China: Causes and consequences

The spatial spillovers of housing prices across regions are well documented by a large body of previous studies. This paper tries to investigate the dynamic (time-varying) evolution of spatial interactions and their underlying driving factors intensively. Using a recently developed Generalized Autoregressive Score (GAS) model, this paper examines the time-varying spatial spillovers of housing prices in 70 major and median cities of China from 2006 to 2019. We find that the GAS model can well capture the impact of time-varying critical events of Chinese real estate market on the whole. However, different regions display heterogeneous variation patterns over time. Further investigation shows that inter-regional labor mobility and trades are two major channels, accounting for 1.25% and 2.58% of the monthly standard deviations of spatial spillover effects from one city to another, respectively. We also characterize and distinguish between three time-varying patterns of spatial spillovers within different regions of China. Our results shed lights on the understanding of spatial spillovers across regional real estate markets across different city network structures within China.     

Environmental regulations in private and mixed duopolies: Taxes on emissions versus green R&D subsidies

In this article, we compare two kinds of environmental regulations—emissions taxes and green R&D subsidies—in private and mixed-duopoly markets in the presence of R&D spillovers. We show that a green R&D subsidy is better (worse) than an emissions tax when the green R&D is efficient (inefficient), irrespective of R&D spillovers, whereas the existence of a publicly owned firm encourages the government to adopt a subsidy policy. We also show that the optimal policy choice depends on R&D efficiency and spillovers. In particular, when green R&D is inefficient and the spillover rate is low (high), the government should choose an emissions tax and (not) privatize the state-owned firm. When green R&D is efficient, however, an R&D subsidy is better, but a privatization policy is not desirable for society, irrespective of spillovers.     

On the peer effects of star students

We estimate the effect that star students have on their siblings’ learning outcomes, measured by their high school grade point average (GPA) and their math grades. To this end, we couple administrative school data on grades with an unusual natural experiment in Peru that generates exogenous variation in the presence of star students at home. We find that star students increase their siblings’ GPA by 0.33 SDs and their math grades by 0.22 SDs. The effect size is inversely related to number of siblings, suggesting that the remaining siblings act as substitutes for the star student.     

Price connectedness between green bond and financial markets

We study price connectedness between the green bond and financial markets using a structural vector autoregressive (VAR) model that captures direct and indirect transmission of financial shocks across markets. Using heteroskedasticity to identify the structural VAR model parameters, our empirical findings reveal that the green bond market is closely linked to the fixed-income and currency markets, receiving sizeable price spillovers from those markets and transmitting negligible reverse effects. We also show that, in contrast, the green bond market is weakly tied to the stock, energy and high-yield corporate bond markets. These findings have implications in terms of portfolio and risk management decisions for environmentally aware investors holding positions in green bonds.     

A Welfare-Based Analysis of International Monetary Policy Spillovers at the Zero Lower Bound

We study the welfare effects of international monetary policy spillovers at the zero lower bound, focusing on the effects of forward guidance in a large economy (“foreign”) on its smaller trading partner (“home”) in scenarios motivated by the global financial crisis. We find that foreign forward guidance has an overall prosper-thy-neighbor effect on the home economy as long as it increases foreign welfare. This finding holds under alternative assumptions about exchange rate pass-through or the degree of international financial integration. However, foreign forward guidance may worsen the trade-off between the stabilization objectives of home monetary policy.     

发展竞争、土地供应策略互动与城市用地增长——基于252个城市数据的空间面板模型实证检验

研究目的：针对发展竞争驱动下产生的地方政府土地供应策略，从空间维度上展开进一步分析，解析城市土地供应行为中存在着怎样的空间互动关系。研究方法：运用2007—2017年的城市层面面板数据和空间计量模型进行了实证检验。研究结果：（1）服务于发展竞争的土地供应策略，对本城市和周边城市的用地增长都会产生影响；（2）工业用地价格波动与商住用地价格波动都会产生空间溢出效应，且前者产生的空间溢出效应更强；（3）工业用地价格存在“竞次式”的城市间互动，其价格增长会显著抑制本城市的用地扩张，但会促进周边城市的用地增长；（4）商住用地价格提升会促进本城市用地扩张，并抑制周边城市用地扩张；（5）作为因变量的城市用地规模，在同省/异省的城市间分别存在着“彼此促进”和“此消彼长”两种互动关系。研究结论：区域协调、用地增长两个方面要紧密结合，针对工业用地价格“竞次式”竞争和商住用地价格高价出让，从城市间关系协调入手进行调控政策的设计与创新。     

Aggregate and distributional impacts of China’s household responsibility system

It is 40 years since China started to abandon collective farming, with initial rural reforms in 1978 that culminated in adoption of the household responsibility system (HRS). Existing studies of impacts of these reforms do not consider nonrandom spread of the HRS, spillovers from early adopters, or distributional effects. In this paper, the synthetic control method and spatial autoregressive panel models with autoregressive errors are used to estimate impacts of the HRS that account for these features. The HRS had a significant positive effect on grain output and food supply in China, while also helping to reduce regional inequality.     

Agglomeration economies and university program creation in the knowledge economy

Existing academic literature on the relationship between agglomeration economies and university activities is both under-theorized and relatively sparse in terms of empirical examination. This paper addresses each of these voids by contributing and analyzing a market model of pro-revenue education program creation such as graduate-level executive business education (e.g. EMBA) that reveals some intriguing characteristics. For instance, it shows that demand for these pro-revenue programs is inelastic and therefore uniquely determines their availability. More specifically, we show that through agglomeration economies these types of education programs are more likely to emanate from universities located in metropolitan areas and from less academically prestigious universities. Regression analysis of a cross-section of national public universities lends support to important facets of our formal model by suggesting that agglomeration economies continue to increase the probability of offering EMBA programs through a city size of approximately 2.12 million and that the probability that a given business school will offer an EMBA is negatively related to the academic prestige of the institution to which it is affiliated.     

Volatility spillovers between WTI and Brent spot crude oil prices: an analysis of granger causality in variance patterns over time

There has been an increase in price volatility in oil prices during and since the global financial crisis (GFC). This study investigates the Granger causality patterns in volatility spillovers between West Texas International (WTI) and Brent crude oil spot prices using daily data. We use Hafner and Herwartz’s (2006) test and employ a rolling sample approach to investigate the changes in the dynamics of volatility spillovers between WTI and Brent oil prices over time. Volatility spillovers from Brent to WTI prices are found to be more pronounced at the beginning of the analysis period, around the GFC, and more recently in 2020. Between 2015 and 2019, the direction of volatility spillovers runs unidirectionally from WTI to Brent oil prices. In 2020, however, a Granger-causal feedback relation between the volatility of WTI and Brent crude oil prices is again detected. This is due to the uncertainty surrounding how the COVID-19 pandemic will evolve and how long the economies and financial markets will be affected. In this uncertain environment, commodities markets participants could be reacting to prices and volatility signals on both WTI and Brent, leading to the detection of a feedback relation.
