Consider the choice of a profiling policy where decisions to search for evidence of crime may vary with observable covariates of the persons at risk of search. I pose a planning problem whose objective is to minimise the social cost of crime and search. The consequences of a search rule depend on the extent to which search deters crime. I study the planning problem when the planner has partial ...

When firms form an alliance, it often involves one firm acquiring an equity stake in its alliance partner. Such an alliance lessens the competition, but induces knowledge transfer within the alliance. This paper explores oligopoly models that capture this important link between knowledge transfer and partial equity ownership (PEO). We consider an industry consisting of n + 2 firms, where firm 1...

The advancement of constraint solvers and model checkers has enabled the effective analysis of high-level formal specification languages. However, these typically handle a specification in an opaque manner, amalgamating all its constraints in a single monolithic verification task, which often proves to be a performance bottleneck. This paper addresses this issue by proposing a solving strategy ...

A fundamental primitive in distributed computing is Reliable Message Transmission (RMT), which refers to the task of correctly sending a message from a party to another, despite the presence of byzantine corruptions. In this work we address the problem in the general adversary model of Hirt and Maurer, which subsumes earlier models such as the global or local threshold adversaries. Regarding th...

The goal of sparse recovery is to recover the (approximately) best k-sparse approximation x̂ of an n-dimensional vector x from linear measurements Ax of x. We consider a variant of the problem which takes into account partial knowledge about the signal. In particular, we focus on the scenario where, after the measurements are taken, we are given a set S of size s that is supposed to contain most...

Firms can obtain competitive advantages from their employees’ knowledge sharing behaviors. This paper presents a research model to examine the direct and indirect effects of knowledge management systems (KMS) quality, KMS self-efficacy, organizational climate and attitude on the intention to share knowledge in the new product development process. The hypotheses are tested on data collected from...

Substitution Effects in Parental Investments The paper estimates how parents adjust bride-prices and land divisions to compensate their sons for differences in their schooling investments in rural China. The main estimate implies that when a son receives one yuan less in schooling investment than his brother, he will obtain 0.7 yuan more in observable marital and post-marital transfers as parti...

The paper provides causal estimates of how parents adjust bride prices to compensate sons for di¤erences in schooling investments in rural China. The benchmark estimate imply that when a son receives one yuan less in schooling investment than his brother, he will obtain 0.4 yuan more in his marital transfers as partial compensation. Accounting for measurement error in schooling expenditure,disc...

This paper describes a new planner, HiPOP (Hierarchical Partial-Order Planner), which is domain-configurable and uses POP techniques to create hierarchical time-flexible plans. HiPOP takes as inputs a description of a domain, a problem, and some optional userdefined search-control knowledge. This additional knowledge takes the form of a set of abstract actions with optional methods to achieve t...
