We propose a simple‐to‐implement panel data method to evaluate the impacts of social policy. The basic idea is to exploit the dependence among cross‐sectional units to construct the counterfactuals. The cross‐sectional correlations are attributed to the presence of some (unobserved) common factors. However, instead of trying to estimate the unobserved factors, we propose to use observed data. We use a panel of 24 countries to evaluate the impact of political and economic integration of Hong Kong with mainland China. We find that the political integration hardly had any impact on the growth of the Hong Kong economy. However, the economic integration has raised Hong Kong's annual real GDP by about 4%.

This paper provides an analysis of global warming policy as the provision of a global public good. Using a regional model composed of thirteen world regions, the paper shows how disparate incentives among the regions hinder a shift from a Business As Usual (BAU) policy to a Globally Optimal Policy (GOP). In the BAU scenario, there will be large variations in impacts from warming across the regions, meaning some countries have little incentive to participate in collective agreements. Under the GOP scenario, negative impacts from global warming will be significantly reduced in some regions resulting in strong incentives for these regions to press for action. The paper finds that an optimal regulation could save Europe, India, and Africa hundreds of billions of dollars per year by the end of this century, but would cause additional costs to China, Russia, Canada and the USA. Under the optimal regulatory framework, higher levels of abatement are required for developing countries, worsening the existing climate equity problem. 相似文献

We investigate whether the urban flight from more to less dense locations identified by previous housing studies for the early COVID period is a temporary, pandemic-induced phenomenon, or long-term trend. We focus on the period of 2017–2022, 14,961 single-family home transactions from Southwestern Ontario, and three housing market metrics. Our results for sales price in the early pandemic periods are in line with previous studies. However, our results for sales price in the last pandemic phase (2022), marketing time, and visit activity suggest that the urban flight was a temporary phenomenon characteristic of the early COVID phases. 相似文献

This study investigates the factors of members' supportive behavioral intentions to donate and recommend membership to others in the context of engineering professional membership associations. Using data collected from 3,464 members across three engineering professional membership associations, this study found that age, past donation experience, personal and professional benefits, gender, income, and longevity in the field were significant factors to determine giving intention, while personal benefits, professional benefits, past behaviors (donation and volunteering), and longevity in the field were predictors of membership recommendation intentions of engineering professionals. 相似文献

This study finds that the growth of index options open interest has a significant relation with future stock market returns. We propose a theoretical model that considers hedgers and informed traders in the options market and suggests that hedgers fully utilize options according to their expectations of future stock returns. The empirical results show that the growth of out-of-the-money call options open interest is significantly related with future stock market returns. These findings provide supporting evidence for our theoretical model. 相似文献

Over the past few decades, the skilled–unskilled hours differential for U.S. men increased when the skill premium rose sharply, in contrast with dominant income effects. Based on PSID data, we show that over the 1967–2000 period, skilled men experienced a three times larger increase in wage volatility than unskilled men. With the rise in wage volatility, our general equilibrium incomplete markets model generates a 2.7 hours increase in the hours differential whereas it increased by 1.4 hours in the data. We find that hours adjustments are important for self‐insurance in the short run, whereas precautionary savings play a crucial role eventually. 相似文献
