Less cheating? The effects of prefilled forms on compliance behavior

As a consequence of digital transformation, individuals are often confronted with prefilled forms or prefilled data entry masks. In situations where cheating and lying are of concern, prefilling might reduce dishonest behavior. In a controlled experiment, we investigate how correctly and incorrectly prefilled forms influence compliance behavior. We frame our experiment as filing the annual income tax return. We show that correct prefilling enhances compliance. However, in cases of incorrect prefilling, we observe asymmetric effects. If prefilled income is lower than true income, we find no positive compliance effect, and compliance is on the same level as with blank forms. If prefilled income is higher than true income, prefilling still has a positive effect on compliance. In that case, compliance is on the same level as with correctly prefilled forms and higher than with blank forms. Our study contributes to the literature on cheating and lying by showing that prefilled forms affect compliance.     

论《了不起的盖茨比》的"奇特化"艺术

菲茨杰拉德在其代表作《了不起的盖茨比》中对“奇特化”艺术手法的运用极为出色,主要表现为题材的奇特化、奇特化的场景和奇特化的叙述视角等几种形态,从而把一个平淡无奇的三角恋爱故事题材雕刻成了一部充满了被扭曲的浪漫情调的悲剧性作品。     

Liberalization of services in Europe: Polish perspective on economic implications of the Services Directive

The original EU Service Directive proposal met widespread opposition and was subsequently narrowed down. Some believed that the competition from the New Member States would endanger the situation of the “old” EU service providers. We assess the importance of the Service Directive for Poland and other EU members by performing a revealed comparative advantage analysis and a computable general equilibrium simulation of the outcome. The liberalization provides minimal welfare gains for Poland and the main opponents of the Service Directive, while they are expected to be higher for small economies open to trade in services.     

Does inflation targeting lower inflation and spur growth?

Over the last few decades several countries have turned to inflation targeting as a policy choice for instilling stability into their economies. Prior studies have shown that inflation targeting has reduced inflation in those countries without significantly impacting GDP. This study seeks to improve upon these results by identifying the impact of timing on the policy decision as well as its impact as related to specific regions of the world. The focus is on developing countries across six regions. We find significant regional variation in developing countries in our sample in terms of the direction of changes in inflation following a switch to the inflation targeting policy. Moreover, although the impact of inflation targeting on real GDP is minimal overall, there is a statistically significant increase in real GDP among developing countries in certain regions only, namely, Europe, Latin America, and the Middle East.     

ON FRAGILE GROUNDS: A REPLICATION OF “ARE MUSLIM IMMIGRANTS DIFFERENT IN TERMS OF CULTURAL INTEGRATION?”

This study is a replication of “Are Muslim Immigrants Different in terms of Cultural Integration?” by Alberto Bisin, Eleonora Patacchini, Thierry Verdier and Yves Zenou, published in the Journal of the European Economic Association, 6, 445–456, 2008. Bisin et al. (2008) report that they have 5,963 observations in their study. Using their empirical setup, we can only identify 1,901 relevant observations in the original data. After removing missing values we are left with 818 observations. We cannot replicate any of their results and our estimations yield no support for their claims.

Optimal Berry–Esseen bound for parameter estimation of SPDE with small noise

We investigate a rate of convergence on asymptotic normality of the maximum likelihood estimator (MLE) for parameter $\theta$ appearing in parabolic SPDEs of the form

$d{u}^{?}(t,x)=(A_0+\theta A_1)u^{?}(t,x)dt+?dW(t,x),$

where $A_0$ and$A_1$ are partial differential operators, $W$ is a cylindrical Brownian motion (CBM) and $?\downarrow 0$. We find an optimal Berry–Esseen bound for central limit theorem (CLT) of the MLE. It is proved by developing techniques based on combining Malliavin calculus and Stein’s method.
