Greener fleet, cleaner air : how Low Emission Zones reduce pollution

Aydin, Eren; Gehrsitz, Markus; Traxler, Christian - 2024

Using a stacked differences-in-differences approach, we study the effects of Low Emission Zones (LEZs) in Germany. The implementation of stage 1 and 2 LEZs, which banned the most pollution-intensive vehicles from city centers, significantly reduced PM10 concentrations. The most restrictive third...

On the effects of COVID-19 safer-at-home policies on social distancing, car crashes and pollution

Brodeur, Abel; Cook, Nikolai; Wright, Taylor - 2020

In response to COVID-19, dramatic safer-at-home policies were implemented. The understanding of their impacts on social distancing, travel and pollution is in its infancy. We pair a differences-in-differences framework and synthetic control methods with rich cellular tracking and high frequency...

Keep your clunker in the suburb : Low Emission Zones and adoption of green vehicles

Wolff, Hendrik - 2014

Spatial distribution and leakage effects are of great policy concern and increasingly discussed in the economics literature. Here we study Europe's most aggressive recent air pollution regulation: Low Emission Zones are areas in which vehicular access is allowed only to vehicles that emit low...

Testing for restricted stochastic dominance

Davidson, Russell (contributor); … - 2006

Asymptotic and bootstrap tests are studied for testing whether there is a relation of stochastic dominance between two distributions. These tests have a null hypothesis of nondominance, with the advantage that, if this null is rejected, then all that is left is dominance. This also leads us to...

The identification and economic content of ordered choice models with stochastic thresholds

Cunha, Flávio (contributor); Heckman, James J. (contributor) - 2007

This paper extends the widely used ordered choice model by introducing stochastic thresholds and interval-specific outcomes. The model can be interpreted as a generalization of the GAFT (MPH) framework for discrete duration data that jointly models durations and outcomes associated with...

Uncertainty and the politics of employment protection

Vindigni, Andrea (contributor) - 2008

This paper investigates the role that idiosyncratic uncertainty plays in shaping social preferences over the degree of labor market flexibility, in a general equilibrium model of dynamic labor demand where the productivity of firms evolves over time as a Geometric Brownian motion. A key result...

Dynamic efficiency and pareto optimality in a stochastic OLG model with production and social security

Barbie, Martin; Hagedorn, Marcus; Kaul, Ashok - 2000

We analyze the interaction between risk sharing and capital accumulation in a stochastic OLG model with production. We give a complete characterization of interim Pareto optimality. Our characterization also subsumes equilibria with a PAYG social security system. In a competitive equilibrium...

The virtue of being underestimated : a note on discriminatory contracts in hidden information models

Schnedler, Wendelin - 2001

A standard hidden information model is considered to study the influence of the a priori productivity distribution on the optimal contract. A priori more productive (hazard rate dominant) agents work less, enjoy lower rents, but generate a higher expected surplus.
