By studying various conflicts and their progression into wars, we aim to expose underlying patterns in stock market reactions. First, we conduct an event study to assess the stock market reactions to seventeen modern invasions from 2001 to 2022. We calculate cumulative abnormal returns for the respective stock market and each invasion. Furthermore, we introduce a regression model highlighting differences in stock market reactions between advanced and emerging countries. The regression model contributes to understanding the relationship between cumulative abnormal returns and each country’s geographic and economic characteristics. Invasions generally have a negative impact on stock markets, with emerging markets showing greater sensitivity and more negative reactions to invasions than advanced stock markets. Furthermore, the findings suggest that underlying drivers play a role in explaining abnormal returns during invasions.</div></div>","PeriodicalId":51439,"journal":{"name":"European Journal of Political Economy","volume":"86 ","pages":"Article 102643"},"PeriodicalIF":2.3,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143170600","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results show that the vote is informative. Households revise their subjective inflation forecast after receiving information about the vote. Information about unanimity or dissent causes a wider individual distribution of future inflation for those households that were relatively certain before the treatment. For the remaining 60% of households, this information reduces uncertainty. Information about dissent increases uncertainty more than information about a unanimous vote, though the difference is not statistically significant.

As an extension, we also study the role of terrorism in wealth inequality, uncovering similar linkages. Our findings imply that democracies see lower levels of income inequality in the absence of terrorism but increases in inequality as terrorist activity grows, while inequality in non-democratic countries is not affected by terrorism. Exploring potential transmission channels, we show that terrorism does not have distributional consequence by damaging the economy. Rather, in democracies terrorism leads to lower levels of redistribution via taxation and transfers. This finding is consistent with our theoretical argument that terrorism elicits a policy response in the form of lower levels of redistribution especially from democratic governments due to their dependence on broad electoral support to stay in power.</div></div>","PeriodicalId":51439,"journal":{"name":"European Journal of Political Economy","volume":"86 ","pages":"Article 102640"},"PeriodicalIF":2.3,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143170590","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We show that uniform fines are optimal when harm from crime is low, non-monetary sanctions when it is high, and day fines in the intermediate region.

Our findings reveal a reduction in both the total number of cars purchased and their average CO2 emissions, with an uptick in the market share of low-emission vehicles and a corresponding decrease in the market share of high-emission counterparts. We test for two potential mechanisms at work: one mediated by an increase in environmental awareness, the other induced by a rational anticipation of future stricter regulations.

Selectors may promote quality candidates and have an informational advantage over voters, but quality need not be the key criterion for nominations, and voters may be sufficiently informed to correct inferior decisions. We empirically examine whether the type of principal responsible for the selection affects individual parliamentary work (attendance, bills, amendments, questions, speeches). Flexible-list proportional representation systems are both interesting and analytically useful in this context, since seats within parties are first allocated to candidates reaching a certain number of personal votes, while any remaining seats are awarded based on the pre-electoral list rank. This allows us to compare three types of elected candidates: selector-chosen, voter-chosen, and doubly-chosen representatives. Analysing data from the Czech Republic in the period between 2002 and 2021, we find that voters have a stronger preference for candidates with high formal education than selectors. We do not find differences in parliamentary behaviour between selector-chosen and voter-chosen types. The results speak against a potential trade-off between giving voters more influence on within-party seat allocation and the quality of chosen representatives.</div></div>","PeriodicalId":51439,"journal":{"name":"European Journal of Political Economy","volume":"85 ","pages":"Article 102618"},"PeriodicalIF":2.3,"publicationDate":"2024-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142701407","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
