Managing Procurement Auction Failure: Bid Requirements or Reserve Prices?

The RAND Journal of Economics, EarlyView.
ABSTRACT This paper examines bid requirements, where the government may cancel a procurement contract unless two or more bids are received. Using a first‐price auction model with endogenous entry, we compare the bid requirement and reserve price mechanisms in terms of auction failure and procurement costs.

Mandatory Annuitization in the SME Pension Fund in Korea: Welfare and Retirement Adequacy

Asia-Pacific Journal of Financial Studies, EarlyView.
Abstract The collective retirement pension fund for workers in small and medium‐sized enterprises (SMEs) has recently been introduced in Korea (the “Blue Seed” plan), yet retirement wealth is typically withdrawn as a lump sum, leaving retirees exposed to longevity risk.

On stochastic orderings between residual record values

In this paper we establish some stochastic ordering results among residual record values in two sample problems. We also discuss some applications.k-records Nonhomogeneous Poisson process Minimal repair process Gamma and beta distributions Likelihood ...

An irreversible investment model with a stochastic production capacity and fixed plus proportional adjustment costs [PDF]

This paper studies the problem of a company which expands its stochastic production capacity in irreversible investments by purchasing capital and faces both fixed and proportional costs.

Composite marginal likelihood estimation of higher‐order diagnostic classification models under high dimensionality

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Although full‐information maximum likelihood (FIML) estimation is widely used for diagnostic classification models (DCMs), its computational efficiency deteriorates sharply in high‐dimensional settings. This scalability challenge is increasingly critical as DCMs are applied to large‐scale assessments, psychological testing and longitudinal ...

Calibrating Bayesian inference

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Bayesian statistics has gained popularity in psychological research due to its intuitive uncertainty quantification and convenient information‐updating rules. In many applications, however, prior distributions are introduced merely as instruments to facilitate computation, rather than as representations of genuine subjective belief ...

Multivariate stochastic orderings among different financial markets

, 2014
In this paper, starting by a recent classification of stochastic orderings consistent with preferences, we show how risk/variability of multivariate measures can be applied to determine dominant sectors markets in different financial contexts of ...

Circles of Confidence for Multi‐Label Geometry Completion

Computer Graphics Forum, EarlyView.
Abstract Inside–outside classification is widely used for geometry processing tasks such as surface reconstruction, geometry completion, and calculating signed distance fields. We introduce a new integral formulation of this problem, which assigns confidence scores that points are inside or outside, given incomplete boundary geometry.

Medial Axis Aware Learning of Signed Distance Functions

Computer Graphics Forum, EarlyView.
Abstract We propose a novel variational method to compute a highly accurate global signed distance function (SDF) to a given point cloud. To this end, the jump set of the gradient of the SDF, which coincides with the medial axis of the surface, is explicitly taken into account through a higher‐order variational formulation that enforces linear growth ...
