The adoption of the Warsaw mechanism on loss and damage has again highlighted the North-South divide in the part of the UNFCCC negotiations dealing with international climate finance. Current estimates put required funding from rich countries at 50 to 100 billion Euros per year to induce...

Internet-based platforms are increasingly being used by governments around the world to facilitate public engagement with citizens. However, it remains an open question whether participation through these platforms can actually enable citizens to influence policies. We address this question by...

School vouchers are one of the most contested issues in educational policy. Yet, various survey data often yield different results on support for vouchers {Moe 2001}. Voucher opinions are better understood by looking at American people into several demographical and geographical segments....

Our mi package in R has several features that allow the user to get inside the imputation process and evaluate the reasonableness of the resulting models and imputations. These features include: choice of predictors, models, and transformations for chained imputation models; standard and binned...

The fundamental problem of causal inference is that an individual cannot be simultaneously observed in both the treatment and control states (Holland 1986). Propensity score methods that compare the treatment and control groups by discarding the unmatched units are now widely used to deal with...

We propose a new prior distribution for classical (non-hierarchical) logistic regression models, constructed by first scaling all nonbinary variables to have mean 0 and standard deviation 0.5, and then placing independent Student-t prior distributions on the coefficients. As a default choice, we...

Numerous scholars and policy advisors have in the past few years called for “climate clubs” – small groups of countries moving ahead in climate policy outside the UNFCCC, and empirical examples for such “minilateral” organizations include the now defunct Asia-Pacific Partnership and...

In this paper we are interested in the relationship between globalization, political institutions (notably, democracy) and international environmental commitments. This relationship has been the subject of a particularly intensive debate and the existing literature offers a wide range of partly...

We study the effects of economic globalization (liberalization of international trade and investment flows) on the environment in the context of a model that integrates standard factor endowment theory (FET) with the pollution haven hypothesis (PHH). Both FET and PHH imply that inward investment...
