Lower Drug

Innovation is the key to the development of the pharmaceutical industry. The pilot program of China’s “4 + 7” volume-based procurement policy (“4 + 7” procurement policy) brings the drug price back to a reasonable level through trading procurement quantities for lower drug prices. The policy manages to reduce the burden of the health care system, improve efficiency, and push the pharmaceutical industry to transform and update from the era of high gross profit of generic drugs to innovative drugs. So far, few studies have investigated the influence of the volume-based procurement policy on the innovation of pharmaceutical firms. By combining the event study and Difference-in-Difference (DiD) methodology, this study finds that the abnormal return (AR) of firms with high R&D intensity is lower than that of firms with low R&D intensity during the event window period. Moreover, further analysis identifies the moderating effect of firm size and firm type. Specifically, the results show that the negative influence of high R&D intensity on abnormal return (AR) during the announcement of the “4 + 7” procurement policy is stronger in large firms and innovative pharmaceutical firms. Finally, we discuss the policy implications of our study.

Study Approach

The electricity sector was negatively impacted by the coronavirus disease (COVID-19), with considerable declines in consumption in the initial phase. Investors were in turmoil, and stock prices for these companies plummeted. The aim of this paper is to demonstrate the significant negative influence of the pandemic on abnormal returns for the electricity sector, specifically for traditional and renewable companies and the influence of ESG scores, using the event study approach and multi-variate regressions. Our results show that the pandemic indeed had a negative impact on the electricity sector, with renewable electricity companies suffering a sharper decline than traditional ones. Moreover, we find that ESG pillar scores affected electricity companies differently and are sector-specific. For renewable electricity companies, the returns were positively influenced by the environmental ESG scores and negatively by governance ESG scores.

Purpose – The purpose of this paper is to examine the trade performance, revealed comparative advantage and trade specialisation indices of Indian pharmaceutical in the post-modified Indian Patent Act. Design/methodology/approach – The main data sources for this paper are United Nations Conference on Trade and Development, PROWESS of Centre for Monitoring Indian Economy, Government of India reports and Reserve Bank of India databases. Revealed comparative advantage index (RCAI) and trade specialisation coefficient (TSC) have been calculated in the study. Findings – India is ranked third in regard of TCS, far behind Ireland and Israel. While Ireland has moved up the value chain faster after 1995, Israel has moved up swiftly after 2000 through global production network and supply chain. The Indian pharmaceutical industry, on the other hand, has largely capitalised on its low-cost production of generic drugs and a large domestic market. The RCAI also supports the results of TSC. India is positioned at 11th place, far behind Ireland, which stands tall at the top with distantly followed by Israel, Switzerland, Belgium, the UK, etc. Practical implications – The study shows the policy implications for future sustainable development of the industry as the new IPR regime has given opportunities as well as threats to both domestic pharmaceutical companies as well as the multinational corporations. The Indian pharmaceutical industry can be a good learning experience for other developing countries hopeful to enter the global market for generic drugs. Originality/value – There are no major studies providing detailed analyses of India’s comparative advantage vis-à-vis other leading exporters of pharmaceutical products in the world. This study endeavours to fill this gap. It also attempts to capture recent trends in exports and imports during the global recession period.

Tsunami Earthquake

Natural disaster often brings damage to the economy, including the decrease of stock’s market value. For this reason, this study aims to determine the effect of the tsunami earthquakes in Lombok in 2018 on abnormal returns and cumulative abnormal returns of insurance companies. This study used the event study approach, with three days window period after the three tsunami earthquakes from July to August 2018. The sample of this study is the stock price of 14 insurance companies listed on the Indonesia Stock Exchange. To test whether abnormal return exists, a one-sample t-test was used on the average abnormal and cumulative returns. The results show that the tsunami earthquake disasters in Lombok in 2018 have a significant effect on cumulative abnormal returns of insurance companies stocks, and this effect even bigger on the third tsunami. This finding shows that the market reacts to continuous disaster by considering the earthquake as negative information and thus decrease the stock price. This study implies that investors may buy the stocks after the disaster to get a cheaper price or hold the stocks to avoid loss.

This research discusses the stock abnormal return effect of warrants to its underlying stock on its listing and maturity date. This study sample is the stock price changes of stocks backed with a warrant in the Indonesian stock market for the year 2008 to 2018—using an event study approach to observe stock abnormal return effect on the listing and maturity date of warrants. The results of this research are that we find a significant negative abnormal return around the warrants' listing date. On the warrants' expiration date, we find a significant negative effect before and after the money warrants' maturity date. However, a different result is obtained for the observation of out-of-the-money warrants that do not show any significant abnormal return on the event window.

This paper uses a standard event study methodology. Data relating to the stock market index has been collected from the website of Pakistan Stock Exchange and relating to political events has been collected from the newspapers of Business Recorder and DAWN. A total of 18 political events was considered in the study out of which 08 events were coded as positive and other 10 were deemed negative. The first day abnormal return, a five-day cumulative abnormal return and ten-day cumulative return was calculated for all of the events. This study found evidence that political events affected the stock market in Pakistan, but their impact is different considering the economic and political implications of these events. Certain events had the strongest impact on the stock market like Nuclear tests for effective defense, the Supreme Court had revoked the Presidential order and Nawaz Sharif had been reinstated, General elections held in the country and the 14th amendment because 14th amendment was related to the elimination of corruption in political parties.

Profitability is used as a prime indicator to measure the sustainable performance of an organization. The current study made an attempt to apply the DuPont model to investigate the multilevel profitability determinants for the pharmaceutical industry of India. The study also estimates an empirical model to predict the association of profitability with factors such as profit margin, asset utilization, leverage, interest load and tax load of firms in the pharmaceutical industry of India. For this purpose, a dataset for 170 companies from 2010–2011 to 2018–2019 was analysed initially by using panel data regression followed by stepwise panel data regression. The study successfully applied and tested the DuPont model with respect to the firms of the pharmaceutical industry in India. It was found that the factors such as profit margin, asset utilization and leverage had a significant positive effect on the firms’ profitability and the factor interest load had a significant negative effect on the firms’ profitability. The tax load does not have an impact on the profitability of the pharmaceutical firms in India. These findings are expected to provide a guide for understanding the profitability of the firms in a better way.

The outbreak of the COVID-19 epidemic has had an adverse effect on China's economy. This paper uses the event study method to test and measure the impact of the open market reverse repo (OMRR) operation on the Chinese stock market. The results show that the OMRR operation generates a positive daily abnormal return and a positive daily cumulative abnormal return on average for all stocks. The impact is larger for non-state-owned enterprise (non-SOE) firms than for SOE firms, stocks of non-Hubei provinces than those of the Hubei province, and for stocks of the information transmission and technology industry than those of other industries. We suggest that our government implement more prudent monetary policies and more proactive fiscal policies.
