Can natural disasters have positive consequences? Investigating the role of embodied technical change

It has been suggested that disasters might have positive economic consequences, through the accelerated replacement of capital. This possibility is referred to as the productivity effect. This effect is investigated using a model with embodied technical change. In this framework, disasters can influence the production level but cannot influence the growth rate, in the same way than the saving ratio in a Solow-like model. Depending on reconstruction quality, indeed, accounting for embodied technical change can either decrease or increase disaster costs, but is never able to turn disasters into positive events. Moreover, a better but slower reconstruction amplifies the short-term consequences of disasters, but pays off over the long-term. Regardless, the productivity effect cannot prevent the existence of a bifurcation when disaster damages exceed the reconstruction capacity, potentially leading to poverty traps.     

Can Google data help predict French youth unemployment?

According to the growing “Google econometrics” literature, Google queries may help predict economic activity. The aim of our paper is to test whether these data can enhance predictions of youth unemployment in France.Because we have weekly series on web search queries and monthly series on unemployment for 15- to 24-year olds, we use the unobserved components approach in order to exploit all available information. Our model is estimated with a modified version of the Kalman filter, taking into account the twofold issue of non-stationarity and multiple frequencies in our data.We find that including Google data improves unemployment predictions relative to a competing model that does not employ search data queries.     

Can 1-day candlestick patterns be profitable on the 30 component stocks of the DJIA?

We set out in this study to conduct a comprehensive analysis of the profitability of every possible 1-day candlestick pattern using data on the 30 component stocks of the Dow Jones Industrial Average index. Our study involves a very lengthy sample period running from January 1974 to December 2009, with the results revealing a noticeable increase in the predictive power of 1-day candlestick patterns from 1992 onwards. Our evidence shows that several of the patterns may well prove to be profitable for the Dow Jones Industrial Average stocks. The robustness of our results is subsequently confirmed based upon a bootstrap analysis.     

Can media drive the electorate? The impact of media coverage on voting intentions

A growing literature uses media data to explain perception and behaviour in the economic and political context. In this paper, we investigate how media coverage affects political preferences, namely voting intention. For our empirical analysis, we merge 14 years of human-coded data obtained from leading media in Germany with results of the comprehensive German Politbarometer survey from February 1998 through December 2012. In contrast to the existing literature, we do not utilize access to certain media outlets, but use the tonality of articles and newscasts on political parties and politicians based on human coded media data. To account for endogeneity, we employ instrumental variable probit estimations. In addition, we control for a multitude of (internal) personal characteristics, such as age, and gender, as well as for (external) macroeconomic variables, such as business climate, unemployment, and inflation. The results show that media coverage of a political party has a positive and significant effect on the voting intention for this party. When media outlets cover a political party more positively, the electorate has a greater tendency to vote for it. Hence, we conclude that the electoral success or failure of political parties is at least partially caused by the media coverage on them. This hints on the special responsibility of media in democracies.     

Can a Focus on Breakthrough Technologies Improve the Performance of International Environmental Agreements?

In a recent paper, Barrett (Am Econ Rev 96(2):22–25, 2006) reaches the conclusion that in general the answer to the question in the title is no, except for a special case in which technology adoption involves increasing returns (network externalities). We show in this paper that a focus on the R&D phase in the development of breakthrough technologies can also increase the possibilities for cooperation.     

Can fiscal redistribution undo skill-biased technical change?: Evidence from the French experience

The inequality of labor earnings among working-age individuals has gone up in all western countries during the past 25 years, either through rising wage inequality (US, UK) or through rising unemployment (Continental Europe). Policy regimes did matter a great deal, however, as far as the inequality of disposable income is concerned. In a country like France, transfers to the unemployed were sufficiently massive to prevent income inequality from rising. This paper argues that the way fiscal redistribution has managed to counteract skill-biased technical change in countries like France is somewhat paradoxical. The same distributive stability could have been obtained at a lower cost by following a job subsidies strategy rather than an income maintenance strategy, simply because it is always less costly to have people at work producing something. We explore several potential explanations for this paradox.     

Does college football impact the size of university applicant pools and the quality of entering students?

The role played by collegiate athletics in furthering the mission of institutions of higher education has been one of the more active research streams in the economics literature. Two areas of emphasis in this particular genre concern the relationship between athletics success and the size of a university’s applicant pool, and the relationship between athletics success and the quality of a university’s incoming class. This study extends both lines of research above by employing a unique panel data set consisting of 10 institutions that either added or eliminated college football between 1997 and 2015 in order to examine the impact of the presence of college football programme on both the size of university applicant pools and the quality of the students chosen for admission. Results from a panel data estimator presented here suggest that the size of their applicant pool shrinks the year following discontinuation of a college football programme. In the case of ACT scores, the results are similar, indicating that the ACT scores of incoming freshmen decrease after discontinuation of football.     

How does the internet affect migration decisions?

This article provides new evidence on the impact of the internet on migration decisions. I find that an increase in internet adoption among migrant-sending countries reduces the stock of migrants from these locations. The results are robust to a number of specifications, including an instrumental variable approach that addresses the endogeneity of internet adoption. The findings suggest that the internet may weaken the importance of push factors in the decision to migrate, and that these effects outweigh declines in mobility costs.     

What determines the value of recommendation change? A preliminary analysis

This article determines the condition under which recommendation changes relative to consensus recommendation and recommendation changes relative to analyst’s previous recommendation are valuable. We show that recommendation upgrades (downgrades) relative to consensus recommendation are followed by significantly positive (negative) short-term returns whenever consensus recommendation represents convergence of analysts’ opinions. We also show that as the standard deviation associated with consensus recommendation increase, the value of recommendation changes reduce significantly. This article also shows that recommendation upgrades (downgrades) relative to analyst’s previous recommendation are followed by significantly positive (negative) short-term returns whenever interval between two consecutive recommendations is relatively short. We also show that, as the interval between two consecutive recommendations increase, the value of recommendation changes reduce significantly. Our results are robust across various subsamples based on size and region.     

Can consumption of convenience products reveal the opportunity cost of time?

I examine how people’s consumption of time-saving products can be used to estimate the shadow value of time. I use a household production model to motivate an empirical approach that can be implemented using survey data.     

Can statisticians beat surgeons at the planning of operations?

The planning of operations in the Academic Medical Center is primarily based on the assessments of the length of the operation by the surgeons. We investigate whether duration models employing the information available at the moment the planning is made, offer a better alternative. Our empirical results indicate that statistical methods often do better than surgeons. This does not imply that the surgeons’ predictions do not contain valuable information. This information is a key explanatory variable in our statistical models. What our conclusion does entail is that a correction of the predictions of surgeons is possible because they are often under- or overestimating the actual length of operations.     

Can social spending cushion the inequality effect of globalization?

This paper examines whether social spending cushions the effect of globalization on within‐country inequality. Using information on disposable and market income inequality and data on overall social spending, and health and education spending from the ILO and the World Bank/WHO, we analyze whether social spending moderates the association between economic globalization and inequality. The results confirm that economic globalization—especially economic flows—associates with higher income inequality, an effect driven by non‐OECD countries. Health spending is strongly associated with lower inequality, but we find no robust evidence that any kind of social spending negatively moderates the association between economic globalization and inequality.     

The impact of downward social information on contribution decisions

In this paper we study the effect of downward social information in contribution decisions to fund public goods. We describe the results of a field experiment run in conjunction with the fundraising campaigns of a public radio station. Renewing members are presented with social information (information about another donor’s contribution) which is either above or below their previous (last year’s) contribution. We find that respondents change their contribution in the direction of the social information; increasing their contribution when the social information is above their previous contribution, and decreasing their contribution when the social information is below. We hypothesize about the psychological motivations that may cause the results and test these hypotheses by comparing the relative size of the upward and downward shifts. These results improve our understanding of cooperation in public good provision and suggest differential costs and benefits to fundraisers in providing social information.      

The impact of personal beliefs on climate change: the “battle of perspectives” revisited

The paper proposes a multi-agent climate-economic model, the “battle of perspectives 2.0”. It is an updated and improved version of the original “battle of perspectives” model, described in Janssen (1996) and Janssen/de Vries (1998). The model integrates agents with differing beliefs about economic growth and the sensitivity of the climate system and places them in environments corresponding or non-corresponding to their beliefs. In a second step, different agent types are ruling the world conjointly. Using a learning procedure based on some operators known from Genetic Algorithms, the model shows how they adapt wrong beliefs over time. It is thus an evolutionary model of climate protection decisions. The paper argues that such models may help in analyzing why cost-minimizing protection paths, derived from integrated assessment models à la Nordhaus/Sztorc (2013), are not followed. Although this view is supported by numerous authors, few such models exist. With the “battle of perspectives 2.0” the paper offers a contribution to their development. Compared to the former version, more agent types are considered and more aspects have been endogenized.     

Can an Islamic model of housing finance cooperative elevate the economic status of the underprivileged?

A formal home loan is onerous to subprime borrowers in efficient markets. This can deter homeownership for financially strapped individuals, leading to a market failure. This paper proposes a special form of cooperative mortgage financing (practiced in Oman) to overcome this market failure. We integrate the literature of mortgage design with that of informal savings schemes (i.e., ROSCAs/ASCRAs) to illustrate that this mode of financing dissipates credit risk better than the formal mode of financing. It is also resilient to volatility of interest rates and allows prepayments without any additional charges. Finally, we verify the assertions of Besley et al. (1994) and Hart and Moore (1998) that cooperative mortgages are pareto-superior to formal mortgages in special cases.     

Who Can Have a Piece of the Auto Credit Pie?

Buying cars on credit is nothing new in the rest of the world since it has had a history of 80 years internationally. In China, however, it is just starting. As the Chinese government is loosening up controls in this field, foreign financial institutions are busy making preparation to win a piece of the auto credit pie in China. Not to be left behind, domestic financial institutions are gearing up for a battle on the marketplace. The auto credit market in China is fast entering a Warring States period.According to a forecast, demand for motor vehices in China
