This paper constructs a simple model to illustrate that the current food stamp subsidy scheme fails to achieve its aim due to the crowding-out effect. In particular, if the household income is sufficiently low, only the corner solution exists and full subsidy is needed. The optimal food stamp subsidy scheme is identified and the subsidy efficiency rate is introduced to measure the impact on foo...

This study examines the effect of regulatory policy on efficiency under prudential framework among banks listed in the Iranian Securities and Exchange Organization over the period 2003 to 2015. Arellano-Bond estimation method has been patronized to investigate the effect of regulatory policies on efficiency. Results indicate that regulatory policy indicator indexing reserve requirement on inves...

We study experimentally when, why, and how people intervene in others’ choices. Choice Architects (CAs) construct opportunity sets containing bundles of time-indexed payments for Choosers. CAs frequently prevent impatient choices despite opportunities to provide advice, believing Choosers benefit. They violate common behavioral welfare criteria by removing options even when all payoffs are dela...

Can information and communication technologies help citizens monitor their elections? We analyze a large-scale field experiment designed to answer this question in Colombia. leveraged Facebook advertisements sent over 4 million potential voters encourage citizen reporting of electoral irregularities. also cross-randomized whether candidates were informed about the campaign subset municipalities...

Developing Böhm-Bawerk’s (1914) Macht oder ökonomisches Ge-setz, we characterize the different intervention modalities as coercive «fixing» of prices, goods (quantities or modes performing) persons, also with their effects. Given that subjective but real forces underlying market processes respond effects which are opposite to those pursued, «intervener» controller would be induced an in crescen...

The objective of this study has been to develop a typical specification of the Almost Ideal Demand System (AIDS) for Iran’s composition of imports including capital, intermediate and consumer goods. Accordingly, we first test the hypotheses that import demand is homothetic, homogeneous, symmetric, and depends on domestic prices. Then, we estimate the long-run elasticities of the composition o...

We model optimal e-cigarette regulation and estimate key parameters. Using tax changes scanner data, we relatively elastic demand. A demographic shift-share identification strategy suggests limited substitution between e-cigarettes cigarettes. field a new survey of public health experts who report that vaping is more harmful than previously believed. In our model’s average Monte Carlo simulatio...

Welfare programs are often implemented in-kind to promote outcomes that might not be realized under cash transfers. I use a randomized controlled trial of the Mexican government’s Food Assistance Program (‘PAL’) to test whether this form of paternalism is necessary, comparing precisely measured consumption and health outcomes under both inkind food and cash transfers. Importantly, I …nd that ho...
