Bad NGOs? Competition in the Market for Donations and Workers' Misconduct

The Journal of Industrial Economics, EarlyView.
ABSTRACT In this paper, we investigate how competition among NGOs to attract donations shapes the incentives that NGOs provide to their employees. NGOs hire workers to undertake development projects, which are horizontally and vertically differentiated.

Lurking Patent Claims and Strategic Royalty Contracts

The Journal of Industrial Economics, EarlyView.
ABSTRACT This paper analyzes optimal licensing contracts when a licensee faces the risk of future infringement claims by unknown patent holders. In a setting where a noncompeting licensor contracts with a monopolistic manufacturer, fixed‐fee licensing is optimal absent such claims.

Strategic Stake Acquisitions in Rival Firms: Common vs. Cross‐Ownership

The Journal of Industrial Economics, EarlyView.
ABSTRACT We study how a blockholder who controls a firm should acquire a minority stake in a rival: directly, creating common ownership, or indirectly through the controlled firm, creating cross‐ownership. Common ownership generates stronger internalization of competitive externalities and allows the blockholder to capture the resulting gains without ...

Dynamic capital allocation in general insurance

Journal of Risk and Insurance, EarlyView.
Abstract This paper provides a model for allocating capital to different insurance lines with varying development periods for a value‐maximizing insurance company. In our model, the company makes capitalization and exposure decisions considering its capital level and its relevant loss history.

ON THE DERIVATIVE OF SMOOTH MEANINGFUL FUNCTIONS

Croatian Operational Research Review, 2011
The derivative of a function f in n variables at a point x* is one of the most important tools in mathematical modelling. If this object exists, it is represented by the row n-tuple f(x*) = [∂f/∂xi(x*)] called the gradient of f at x*, abbreviated: “the ...

Analysing reforms of social security disability pension provision in a multistage overlapping generations model

Journal of Risk and Insurance, EarlyView.
Abstract This paper introduces a multi‐stage Overlapping Generations (OLG) model of workers and retirees, segmented by disability status and eligibility for Disability Pension (DP) benefits. Extending Gertler (1999) with progressive disability stages of distinct productivity and transition probabilities, and calibrated to US data, the model generates ...

Density‐Valued ARMA Models by Spline Mixtures

Journal of Time Series Analysis, EarlyView.
ABSTRACT This paper proposes a novel framework for modeling time series of probability density functions by extending autoregressive moving average (ARMA) models to density‐valued data. The method is based on a transformation approach, wherein each density function on a compact domain [0,1]d$$ {\left[0,1\right]}^d $$ is approximated by a B‐spline ...

Empirical‐Process Limit Theory and Filter Approximation Bounds for Score‐Driven Time Series Models

Journal of Time Series Analysis, EarlyView.
ABSTRACT This article examines the filtering and approximation‐theoretic properties of score‐driven time series models. Under specific Lipschitz‐type and tail conditions, new results are derived, leading to maximal and deviation inequalities for the filtering approximation error using empirical process theory.

The fundamental theorem of asset pricing with and without transaction costs

Mathematical Finance, Volume 35, Issue 2, Page 567-609, April 2025.
Abstract We prove a version of the fundamental theorem of asset pricing (FTAP) in continuous time that is based on the strict no‐arbitrage condition and that is applicable to both frictionless markets and markets with proportional transaction costs. We consider a market with a single risky asset whose ask price process is higher than or equal to its ...
