G²LM|LIC - Entrepreneurship Education and Teacher Training in Rwanda
No full textAn experiment across 207 secondary schools shall investigate, how a comprehensive teacher training program affects the delivery of a major entrepreneurship curriculum reform in Rwanda. The reform introduced interactive pedagogy and a focus on business skills in the country's required upper secondary entrepreneurship course. In addition to the government's standard training, a random sample of schools received intensive training organized by an NGO for two years. The training consisted of (i) six training sessions during school breaks, ii) exchange visits each term where teachers provided feedback to their peers, and (iii) outreach and support from NGO staff at least twice per year. The program increased teachers' use of active instruction, consistent with the reform's features. These effects on pedagogy did not translate into improvements in student academic outcomes or skills. Treated students increased their participation in businesses by 5 percentage points, or 17% of the control mean, with a commensurate decrease in wage employment, and no effect on overall income. These results suggest substitution between entrepreneurship and employment among students in treated schools
G²LM|LIC - Poor and Rational: Decision-Making under Scarcity
No full textThe authors investigate in a sample of over 3,000 small-scale farmers in Zambia, who were given the opportunity to exchange randomly assigned household items for alternative items of similar value.
Analyzing a total of 5,842 trading decisions over a range of items, including cash, the authors show that exchange asymmetries are sizable and remarkably robust across items and experimental procedures. Using cross sectional, seasonal and randomized variation in financial resource availability, the authors show that exchange asymmetries decrease in magnitude when subjects are more constrained. Consistent with the interpretation that variation in decision stakes drive the results, the authors also show that trading probabilities increase when the value of the items involved is exogenously increased
Replication Data Based on the IZA Evaluation Dataset Survey
No full textThe provided dataset contains survey information on the job search behavior of unemployed job seekers based on the IZA Evaluation Dataset Survey. The survey contains information on respondents who were interviewed 7-14 weeks after they became unemployed between June 2007 and May 2008. Besides covering an extensive set of socio-demographic and household characteristics, the survey data allows a detailed analysis of respondents' job search behavior—including the number of job applications, the geographical search radius and the usage of different search channels—and counseling received from their caseworkers. Arni et al. (2014) provide a detailed documentation of the IZA Evaluation Dataset Survey.
Based on the original data including 17,396 individuals, we only select individuals who are still unemployed and are actively searching for employment at the time of the first interview. This reduces the final sample to 12,326 individuals. In addition, please note that the provided dataset only contains variables which are used in the analysis and hence contains a reduced set of variables compared to the IZA Evaluation Dataset Survey as described in Arni et al. (2014).
In a final step, aggregate regional information measured at the time of the survey at respondents’ place of residence as well as indicators of local labor market characteristics was added to the survey data
STAU
No full textThe data set contains the number of hourly STAUs reported on the website of the ADAC and scraped from the web programmatically by the author (variable name adac) and hourly search intensity for the word stau (German for Traffic Jam) in Germany as obtained from Google Trends (variable name stau). The data collection occurred between September 28 2015 14:59 and November 14 2015 at 13:59
G²LM|LIC - Asymmetric Information on the Skills of Workers and Matching in the Labor Market
No full textThe project studies how employers and job seekers respond to credible information on skills that are difficult to observe, and how this affects matching in the labor market. Whether certificates on workers’ non-cognitive skills are disclosed to both sides of the market during job interviews between young workers and small firms in Uganda are experimentally varied.
The certificates cause workers to increase their labor market expectations, while high-ability managers revise their assessments of the workers’ skills upwards. The reaction in terms of beliefs leads to an increase in positive assortative matching and to higher earnings for workers, conditional on employment.</br
Opinion Copulas, Homophily and Multimodal Marginals
No full textAn empirically founded and widely established driving force in opinion dynamics is homophily i.e. the tendency of "birds of a feather" to "flock together". The closer our opinions are the more likely it is that we will interact and converge. Models using these assumptions are called bounded confidence models (BCM) as they assume a tolerance threshold after which interaction is unlikely. They are known to produce one or more clusters, depending on the size of the bound, with more than one cluster being possible only in the deterministic case. Introducing noise, as is likely to happen in a stochastic world, causes BCM to produce consensus which leaves us with the open problem of explaining the emergence and sustainance of opinion clusters and polarization. We investigate the role of heterogeneous priors in opinion formation, introduce the concept of opinion copulas, argue that it is well supported by findings in Social Psychology and use it to show that the stochastic BCM does indeed produce opinion clustering without the need for extra assumptions
Overexertion of Effort under Working Time Autonomy and Feedback Provision
No full textThe researchers develop an experiment to show that overprovision of costly effort is more likely to occur in work environments with working time autonomy in the absence of feedback. A key feature of the design is that it allows for a clean measurement of effort overprovision by keeping performance per unit of time fixed, which is achieved by calibrating subjects' productivity on a real effort task ex ante. This novel design can serve as a workhorse for various experiments as it allows for exogenous variation of perfor-mance certainty (i.e., by providing feedback), working time autonomy, productivity, effort costs, and the general incentive structure. The project finds that subjects provide significantly more costly effort beyond a level necessary to meet their performance targets in the presence of uncertainty, i.e., the absence of feedback, which suggests that feedback shields workers from overprovision of costly effort
Toll Index
No full textThe Toll Index (TI) is a new monthly indicator for the German business cycle and is offered by the International Data Service Center (IDSC) of IZA as a service to forecasting practitioners and policy makers alike.
The TI measures the monthly transportation activity performed by heavy transport vehicles across the country and has highly desirable availability properties (insignificant revisions, short publication lags) as a result of the innovative technology underlying its data collection.
It is coincident with production activity due to the prevalence of just-in-time delivery. The Toll Index is an early indicator of production as measured for instance by the German Production Index, provided by the Federal Statistical Office - Germany, which is a well-known leading indicator of the Gross National Product. Which we suggest should be established more around the world
Delayed Negative Effects of Prosocial Spending on Happiness
No full textThe data were collected in a behavioral choice experiment with a total of N = 591 student participants at the BonnEconLab of the University of Bonn, Germany, in September 2016.
In the main sample, Lottery Choice (N = 325), subjects chose between two lotteries, Lottery A (with probability 60%: save a human life in expectation by triggering a donation of 350 euros; with probability 40%: receive 100 euros) and Lottery B (with probability 40%: save a human life in expectation by triggering a donation of 350 euros; with probability 60%: receive 100 euros).
In a control condition, Deterministic Choice (N = 221), participants directly decided between saving the human life in expectation and receiving the money. In a third treatment condition, the Calibration Sample (N = 45), the authors elicited the minimal monetary amount that would make a participant indifferent to saving a life in expectation.
The study was approved by the Ethics Committee of the Economics Department at the University of Bonn (reference no. 2016-02), and all subjects provided informed consent before participating
