This study draws on diverse tables and charts, correlation matrices, pair-wise Granger Causality tests, ADRL (General to Specific Approach) test, and a quadratic regression equation estimated by OLS using time series annual data covering the sample period from 1980 to 2017. The results demonstrate that the relationship between inflation and GDP growth is non-linear with a subsistence of a breakpoint, which means the inverted U-shape curve. Moreover, the Granger Causality shows that economic growth does granger cause inflation. The empirical result indicates that when the inflation level reaches the threshold level at 7.84 percent then the economic growth is in peak position. This study proposed that the Bangladesh Bank should maintain the precautious and growth-friendly monetary policy structure by keeping inflation targeting below 7.84 percent, or else the growth might be held back.","PeriodicalId":224430,"journal":{"name":"Decision-Making in Economics eJournal","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127739405","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When can we comprehensively say that f(x2) is ``richer'' than f(x1)? Anderson (1996) proposed a nonparametric quantification for pair-wise welfare-ordering of two countries by their entire income distributions. His algorithm readily computes index values for stochastic dominance of orders 1 to 4, denoted as SD1 to SD4. This paper fills a gap in the literature by providing a simple ranking of n densities by suggesting two new SD-type algorithms, both avoiding pair-wise comparisons. The first new algorithm is exact because it replaces Anderson's trapezoidal approximations subject to truncation errors by exact areas under step-functions defined by empirical cumulative distribution functions, ECDF(xj). Our second new SD-type algorithm uses four orders of differencing of time series data. We use monthly return data on Apple, Microsoft, and Google stocks over the latest 14 years to illustrate. We provide intuitive derivations and include 95% bootstrap confidence intervals for inference on estimated SD-type indexes","PeriodicalId":224430,"journal":{"name":"Decision-Making in Economics eJournal","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124087565","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A representative investor holds subjective beliefs about the underlying asset returns, which he optimally learns from past returns. I derive a closed form option price formula for a European call option in this set up. I show that given this belief structure, investor's subjective expectations about next period price growth are priced in an option, creating a wedge between option implied-variance and realized variance. Time variation in the agent's subjective expectations link this wedge to realized stock returns, helping explain its power to predict stock returns. Further, these subjective expectations also help generate different shapes of option implied-volatility curve. The model can quantitatively replicate key features of index returns and index options with very reasonable parameter values. The findings in this paper suggest that measures of option-implied variance such as VIX are not capturing the true uncertainty expected by agents but are biased in the direction of the investors expectations of future capital gains on the underlying asset.","PeriodicalId":224430,"journal":{"name":"Decision-Making in Economics eJournal","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125966769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Estimated long-run elasticities are higher than their short-run counterparts, which is in line with expectations based on the existing literature. We find price elasticities of -0.418 (long-run) and -0.189 (short run), which indicates that when price increases by 10%, demand tends to reduce by approximately 4% as consumers adjust their consumption behaviour. Prices appear to be more elastic in India rather than USA where studies estimate petrol elasticities to be in the range of -0.02 to -0.04 in the short term. We further find evidence that long-run elasticities are not as high as estimated elsewhere. We address issues around modelling of habit formation, habit persistence, and unobserved heterogeneity. Results are essential for transportation policymaking, especially in the context of taxation, understanding price stability, estimating the effects of duty increases on demand, and the potential implications for carbon taxes. The results are also important for wider policy considerations such as climate protections goals, reducing local emissions, dependency on fossil fuels, and strategic energy security.","PeriodicalId":224430,"journal":{"name":"Decision-Making in Economics eJournal","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116737349","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While numerous campaigns designed to warn and educate consumers about financial fraud exist, there is very little evidence on whether these initiatives are effective at reducing susceptibility to scams. We conduct a randomized experiment among a representative sample of U.S. adults and find that short, online educational interventions can meaningfully reduce fraud susceptibility, and that effects persist for at least three months following a reminder. Investigating mechanisms, we find no evidence that the educational intervention reduced willingness to invest generally, but rather increased knowledge which participants were able to selectively apply. We find that beneficial effects are concentrated among individuals who are more likely to invest, particularly the financially sophisticated. Our results indicate that brief financial education interventions can meaningfully reduce susceptibility to financial fraud.","PeriodicalId":224430,"journal":{"name":"Decision-Making in Economics eJournal","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133668669","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We observe how the normal advantage for the home team of playing in their own stadium was eroded behind closed doors, with no supporters. After designing a three-step sample selection and regression strategy, to get as close as possible to a causal interpretation, the standout effect of an empty stadium was that referees cautioned visiting players significantly less often, by over a third of a yellow card per match or once for every twenty-two fouls. Closed doors matches were different because referees favoured the home team less in their decision making. These results add to the literature describing how home advantage in sports decreased during the Covid-19 pandemic, though many other factors changed at that time besides the emptying stadiums.","PeriodicalId":224430,"journal":{"name":"Decision-Making in Economics eJournal","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129380119","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
