Migrant Smuggling to Europe: A Two‐Sector Model With Directed Search

Review of International Economics, EarlyView.
ABSTRACT In the last decade, combating migrant smuggling has emerged as a top priority for the European Union (EU). An idiosyncratic feature of this market is its dual supply‐side organization, comprising a small number of criminal cartels and a large mass of self‐employed smugglers.

Repelled Point Processes With Application to Numerical Integration

Scandinavian Journal of Statistics, EarlyView.
ABSTRACT We look at Monte Carlo numerical integration from a stochastic geometry point of view. While crude Monte Carlo estimators relate to linear statistics of a homogeneous Poisson point process (PPP), linear statistics of more regularly spread point processes can yield unbiased estimators with faster‐decaying variance, and thus lower integration ...

Bayesian Estimation of Transition Rates in Two‐State Nonhomogeneous Markov Jump Processes With Intermittent Observations: An Honest‐Time Data‐Augmentation Approach

Scandinavian Journal of Statistics, EarlyView.
ABSTRACT A possibly time‐dependent transition intensity matrix or generator (Q(t))$$ \left(Q(t)\right) $$ characterizes the law of a Markov jump process (MP). For a time‐homogeneous MP, the transition probability matrix (TPM) can be expressed as a matrix exponential of Q$$ Q $$.

In‐Work Poverty Transitions Dynamics: The Role of Active Labour Market Policies Across European Nations Using EU‐SILC

Social Policy &Administration, EarlyView.
ABSTRACT This paper investigates the relationship between Active Labour Market Policies (ALMPs) and in‐work poverty (IWP) transitions in Europe. Using EU‐SILC longitudinal data (2017–2020) for 24 countries, combined with Eurostat data on social policy investment, we estimate effects of six ALMP subtypes and for different subsamples (male‐ and female ...
