Contract design in agri-environmental schemes with fixed private transaction costs and countervailing incentives [PDF]

open access: yes
The aim of this paper is to test the relevance of considering private fixed transaction costs for contract design of Agri-Environmental Schemes, when transaction costs are negatively correlated to marginal compliance costs. In order to do so, a principal-

The increasing concentration at industrial markets: the social welfare maximization and possible risks

open access: yesSHS Web of Conferences, 2017
The paper considers impact of entry barriers on the social welfare. Despite the common opinion that entry barriers are always bad, the excessive number of firms means, all pros aside, duplicated fixed costs. It is shown that the socially effective number

Optimizing photoactivation of PA‐mCherry for optical pooled CRISPR screens

open access: yesFEBS Open Bio, EarlyView.
Photoactivatable PA‐mCherry finds widespread use to optically tag individual cells. However, confocal 405 nm UV laser‐scanning (normal scan) is much less efficient than widefield UV illumination, limiting the use of PA‐mCherry on confocal instruments. We remedy this limitation by reporting that rapid and repeated confocal scanning with a low‐intensity,

Fixed Term Contracts, Social Security Rebates and Labour Demand in Italy [PDF]

open access: yes
The availability of a flexible labour force might influence adjustment decisions regarding the rigid part of the labour force. To test this idea, we contrast the use of trainees (fixed-term contracts) and normal-contract workers (open-end contracts) when

Fixed- and flexible-route transit mode selection [PDF]

open access: yesShandong kexue
Selecting between fixed-route and flexible-route bus systems is a critical strategy for improving the operational efficiency of urban public transit. While most existing studies focus primarily on passenger demand, this study adopts a more comprehensive ...

Refinement of amino‐acid conformation vs. difference density maps in time‐resolved serial femtosecond crystallography data analysis

open access: yesFEBS Open Bio, EarlyView.
The dFoCC pipeline starts with observed DED and resting‐state coordinates, which are then used to generate a library of triggered states. Correlation analysis of the calculated DED features of each candidate vs observed DED permits quantitative evaluation of candidate structural quality.

Margin Squeeze in Fixed-Network Telephony Markets – competitive or anticompetitive? [PDF]

open access: yes
This paper looks at the effects of different forms of wholesale and retail regulation on retail competition in fixed network telephony markets. We explicitly model two asymmetries between the incumbent operator and the entrant: (i) While the incumbent ...

Versatile vector tools for efficient protein screening across multiple expression systems

open access: yesFEBS Open Bio, EarlyView.
A unified vector toolkit enables rapid protein expression screening across E. coli, insect, and mammalian cells. A single primer pair amplifies the target gene, which is inserted into any vector via a standardized interface. This streamlined workflow eliminates repeated cloning steps, accelerating the identification of optimal expression conditions for

Fixed Export Costs and Export Behavior [PDF]

open access: yes, 2014
This paper provides a direct test of how fixed export costs and productivity jointly determine firm-level export behavior. Using Chilean data, we construct indices of fixed export costs for each industry-region-year triplet and match them to domestic ...
