Governments worldwide are implementing mass vaccination programs in an effort to end the novel coronavirus (COVID-19) pandemic. Here, we evaluated the effectiveness of the COVID-19 vaccination program in its early stage and predicted the path to herd immunity in the U.S.

Credit guidance is a common policy practice for the governments of each country. Governments adopted credit guidance to sustain economic growth after the global financial crisis in 2008, and after the COVID-19 pandemic outbreak in 2020. When the economy is in a cyclical upswing，governments may also guide credit flows to develop certain industries and to secure macroeconomic safety. When credit guidance is adopted, governments may choose different firms in different sectors. When the economic cyc

This paper uses the nonlinear autoregressive distributed lag (NARDL) model to analyze the different performances of Bitcoin and gold under the impacts of three different uncertainties, namely global economic policy uncertainty (GEPU), US stock market volatility index (VIX) and the CBOE crude oil ETF volatility index (OVX).

Is inflation ‘always and everywhere a monetary phenomenon’ or is it fundamentally a fiscal phenomenon? The answer hinges crucially on the underlying monetary–fiscal policy regime.

The primary goal of this paper is to provide empirical evidence for how non-trade factors attribute to the China-US trade war. Trump’s tweets provide us with a unique perspective. After analysing 31,166 Trump’s tweets, we have the following findings...

We first examine an ETS that covers both electricity and cement sectors and consider an ambitious cap starting in 2017 that will meet the official objective to reduce the carbon-GDP intensity by 60–65% by 2030 compared to 2005 levels. The two ETS-covered industries are compensated with an output-based subsidy to represent the intention to give free permits to the covered enterprises.

The well-known equity home bias has two components: an extensive and intensive margin. Using data on direct stock holdings of U.S. households, we find that the decision to participate in foreign stock markets depends on investor wealth, with richer investors more likely to participate (the extensive margin).
