Information Networks and Collective Action: Evidence from the Women’s Temperance Crusade

How do social interactions shape collective action, and how are they mediated by networked information technologies? We answer these questions studying the Temperance Crusade, a wave of anti-liquor protest activity spreading across 29 states between 1873 and 1874. Relying on exogenous variation in network links generated by railroad accidents, we provide causal evidence of social interactions driving the diffusion of the movement, mediated by rail and telegraph information about neighboring activity. Local newspaper coverage of the crusade was a key channel mediating these effects. Using an event-study methodology, we find strong complementarities between rail and telegraph networks in driving the movement’s spread. (JEL D83, J16, L92, L96, N31, N41, N71)

The Impact of Covid-19 on the Automobile and Allied Sectors

This paper examines the impact of Covid-19 outbreak on the automobile and allied sector. The role of the automobile sector is significant in the overall economy in India. We have used event study methodology to capture the price impact on account of the Covid-19 outbreak. We found that automobile sector and allied sector have witness the negative impact on the event of the pandemic. We have presented the daily and period wise results to provide clear cut understanding about the impact of Covid-19 outbreak on the automobile and allied sectors. This paper contributes in the extreme event literature and help decision makers to hedge their position during the extreme events.

Governmental Announcements and Indian Stock Market: Evidence from Indian Manufacturing Sector

The Indian Manufacturing sector lags behind in contributing to economic devel- opment, as compared to its peer nations and therefore, to boost the sectorís contribution to the economy and to transform the economy into a cashless economy, the government of India had announced three major steps, Make in India, Demonetization and GST. In the present study using event study methodology, the immediate impact of the announcements on the stock of the companies from the Indian Manufacturing sector is examined and found that the announcement of the Make in India positively ináuenced the security returns. In contrast, negative impact on the security prices is witnessed on the announcement of Demonetization, whereas the GST implementation has no impact.

Short-Term Impact of COVID-19 on Indian Stock Market

The onset of the COVID-19 pandemic and lockdown announcements by governments have created uncertainty in business operations globally. For the first time, a health shock has impacted the stock markets forcefully. India, one of the major emerging markets, has witnessed a massive fall of around 40% in its major stock indices’ value. Therefore, we examined the short-term impact of the pandemic on the Indian stock market’s major index (NIFTY50) and its constituent sectors. For our analysis, we used three different models (constant return model, market model, and market-adjusted model) of event study methodology. Our results are heterogeneous and largely depend on the sectors. All the sectors were impacted temporarily, yet the financial sector faced the worst. Sectors like pharma, consumer goods, and IT had positive or limited impacts. We discuss the potential explanations for the same. These results may be useful for investors in safeguarding equity portfolios from unforeseen shocks and making better investment decisions to avoid large, unexpected losses.

Impact of Geopolitical Risk on the Information Technology, Communication Services and Consumer Staples Sectors of the S&P 500 Index

We investigate the effect of geopolitical risk on the returns of firms in the Information Technology, Communication Services, and Consumer Staples sectors within the S&P 500 index. We use the event study methodology and perform more than 17,000 regressions to provide empirical evidence at sector level that geopolitical risk leads to different responses across these three sectors. The response of the Information Technology sector is negative for all event windows under study, except the one spanning 10 days prior to the geopolitical event and 10 days after. The Communication Services sector has positive returns as a result of geopolitical events for all event windows, except the one from the geopolitical event date and 5 days after. The Consumer Staples sector shows a negative impact on geopolitical risk for all event windows except the one from the geopolitical event date and 5 days after, demonstrating a negative correlation to the Communication Services sector.

Impact of Terrorism on KSE 100: Evidence from Karachi

Terrorism is a critical issue throughout the world. In Pakistan, terrorism is one of the major obstacle in the growth of economy. The purpose of the study is to analyze the impact of terrorism in Karachi on the performance of KSE 100. Overall 27 big terrorist activities are considered in four years, ranging from 2011 to 2014. The performance of Karachi stock exchange is measured from the return of KSE 100 index. Moreover, the performance of KSE 100 index against terrorism in Karachi are analyzed through event study methodology and t-test. The result of the study shows that terrorism in Karachi has no significant impact on Karachi stock exchange 100 in all estimation windows. There is a little impact of some pre-event days on post-event days. But overall there is no significant result of terrorism in Karachi on KSE 100. The result highlights that the intensity of terrorist events is an important contributor in signifying the impact of terrorist events on KSE 100 index.

IMPACT OF DEMONETIZATION ON INDIAN BANKING STOCKS: AN EVENT STUDY METHODOLOGY

Demonetization is the withdrawal of a particular form of currency from circulation. In other words, the notes lose their value as a currency. It is an instrument that is used to manage various economic problems such as inflation, corruption, tax evasion, etc. The Indian government on November 8, 2016, decided to demonetize high denomination currencies. This announcement had an impact on several sectors of the Indian economy. This study is an investigation to measure the impact of demonetization announcements on the Indian banking sector. This study employs cumulative abnormal return (CAR) and an event study methodology to measure the impact of the decision on the selected banking stocks. The study shows that demonetization had a significant impact on the stock prices of selected banks. The findings of the study suggest that on the event day, none of the selected stock has shown significant positive abnormal returns. Further on the event day and followed by the event day positive significant ARR is observed indicating demonetization had a significant impact on the stock prices of selected banks. Also, CAR on the event day is not equal to zero indicating the Indian stock market was not efficient for demonetization announcement.

The Impact of Natural Disasters on Economic Growth

This paper estimates the impact of catastrophic natural disasters on economic growth using an event study methodology on a country panel dataset from 1970 to 2019. The severity of the events is determined by the associated mortality. We find that affected economies which, given the way natural disasters are ranked, comprise mainly developing countries, suffer an average loss between 2.1 and 3.7 percentage points (p.p.). The estimated loss is not offset by above-average growth rates in the disasters aftermath. In contrast, when the severity of the events is determined by physical intensity rather than by mortality, which implies a more balanced estimating sample of developed and developing economies, the estimated effects on growth are negligible. Thus, the negative impacts of natural disasters on economic growth are larger for poorer countries, suggesting that the impact of natural disasters on growth is an economic development issue.

Stock Market Reactions to the Comprehensive and Progressive Agreement for Trans-Pacific Partnership’s Approval: Evidence from Vietnam

We examine the stock market performance of Vietnam’s listed firms in response to the country’s approval of the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP). Employing an event study methodology, we first calculate the abnormal returns of all listed Vietnamese firms around the CPTPP’s approval date. Then, we attempt to link these abnormal returns to firms’ characteristics. We find evidence that the announcement of the CPTPP’s approval is associated with positive abnormal returns for Vietnam’s listed firms. We also find considerable heterogeneity in the magnitude and pace of the impacts of the CPTPP’s approval on market returns across Vietnam’s two stock exchanges. However, we fail to reject the null hypothesis that the market did not react to the CPTPP’s approval at the sectoral level.
