On March 11, 2011 the strongest ever recorded in Japan earthquake occurred, also known as the Great East Japan Earthquake, which triggered a powerful tsunami and caused a nuclear accident in one of the world biggest nuclear power stations - Fukushima Daichi. More than six years after the triple...

Landfilling prevails in waste management options in Romania like others new EU members, being contrary to the concept of waste hierarchy promoted in recent years by EC. Waste disposal is done usually in non-compliant landfills and Government established a program to close these sites. This paper...

Models such as the mixed logit are often used to measure the distribution of the marginal value of a good based on discrete choice panel data. There are however serious specification and identification issues that are rarely addressed. The consequences for results may be dramatic. This paper...

Let U be an unobserved random variable with compact support and let e_t be unobserved i.i.d. random errors also with compact support. Observe the random variables V_t, X_t, and Y_t = 1{U +d X_t+e_t V_t}, t = T, where d is an unknown parameter. This type of model is relevant for many stated...

In many stated choice experiments researchers observe the random variables V_t , X_t , and Y_t = 1{U +δ X_t +e_t V_t }, t ≤ T , where δ is an unknown parameter and U and e_t are unobservable random variables. We show that under weak assumptions the distributions of U and e_t and also the...

We introduce a semiparametric smooth coefficient estimator for recreation demand data that allows more flexible modeling of preference heterogeneity. We show that our sample of visitors each has an individual statistically significant price coefficient estimate leading to clearly nonparametric...

In Romania, the issue of economic inequalities and regional convergence is one of the current important topics on which the attention of economic specialists and the decision-making factors is focused. In the current context, the regional policy in Romania is implemented at regional level, the...

We study the role of Dutch colonial institutions on urban development for the megacity of Jakarta, Indonesia. Using historical maps of Dutch settlements and a rich granular database, we implement a boundary discontinuity design comparing locations within 200 meters of Dutch boundaries. We find...

Various social policies and strategies have been deliberated and used within many countries to handle the COVID-19 pandemic. Some of those basic ideas are strongly related to the understanding of human social interactions and the nature of disease transmission and spread. In this paper, we...

Urban green infrastructure, such as parks and reforestation programs, is critical for building municipal resilience to environmental, social, and economic concerns. The Metro Forest Project in Bangkok shows this by converting an abandoned site into a thriving biological forest utilizing the...
