Studying the role of political competition in the evolution of government size over long horizons

Here we argue for the use of cointegration and error correction analysis to combine economic factors that are nonstationary with political factors that are stationary into an empirical model of the evolution of public policy over long periods. The approach is applied to disentangle the contributions of economics and politics to the evolution of public expenditure by the Government of Canada over 130 years. Political competition emerges as the primary political factor affecting government size.     

When Less is More: The Impact of the Regulation on Standard Workweek on Labor Productivity in South Korea

This paper examines the impact of a workweek reduction policy on the labor productivity of manufacturing plants in Korea. Taking advantage of the stepwise introduction of the standard 40‐hour workweek in Korea, we apply a difference‐in‐differences framework to individual‐level cross‐sectional and plant‐level longitudinal data to examine the impact of the policy on working hours and output, respectively. We find that the policy reduced per‐worker hours but increased per‐worker output, which is robust to various specifications and sample restrictions. The observed increase in per‐worker output is likely to be mediated through the increase in the total factor productivity and the amount of capital stock.     

Relevance analysis using revision identifier in MS word

Electronic documents often contain personal or confidential information, which can be used as valuable evidence in criminal investigations. In the digital investigation, special techniques are required for grouping and screening electronic documents, because it is challenging to analyze relationships between numerous documents in storage devices manually. To this end, although techniques such as keyword search, similarity search, topic modeling, metadata analysis, and document clustering are continually being studied, there are still limitations for revealing the relevance of documents. Specifically, metadata used in previous research are not always values present in the documents, and clustering methods with specific keywords may be incomplete because text‐based contents (including metadata) can be easily modified or deleted by users. In this work, we propose a novel method to efficiently group Microsoft Office Word 2007+ (MS Word) files by using revision identifier (RSID). Through a thorough understanding of the RSID, examiners can predict organizations to which a specific user belongs, and further, it is likely to discover unexpected interpersonal relationships. An experiment with a public dataset (GovDocs) provides that it is possible to categorize documents more effectively by combining our proposal with previously studied methods. Furthermore, we introduce a new document tracking method to understand the editing history and movement of a file, and then demonstrate its usefulness through an experiment with documents from a real case.     

Interlocal Collaboration and Local Fiscal Structure: Do State Incentives Matter?

Interlocal collaboration is considered an important tool for cost-saving. States, therefore, have incentivized interlocal collaboration in different ways. To understand the budgetary consequences of interlocal collaboration and state incentives, we examine counties in Nebraska where the State uses two incentive mechanisms—resource restrictions and additional access to restricted revenues granted to counties with collaboration. This study finds that county expenditures are lower when they spend more through collaboration. While this lower spending is related to lower revenues in counties less constrained by state restrictions, the results for counties more constrained are unclear. State incentive structures may matter for such variations.     

Ministerial Leadership and Endorsement of Bureaucrats: Experimental Evidence from Presidential Governments

Scholars have debated what constitutes effective ministerial leadership with respect to administrative competence versus political influence. The authors contribute experimental evidence to this debate through a unique survey design of endorsement experiments. Using original data from 949 national civil servants in South Korea, this article examines civil servants’ assessments of ministerial leadership in three central dimensions of public management: internal management, interbranch coordination, and policy formulation/implementation. Further, existing variation in the characteristics of agencies is used to test whether such variation induces systematic differences in civil servants’ responses. Findings show that that civil servants’ attitudes toward ministerial leadership are asymmetric in nature. Ministers with civil service backgrounds are endorsed in all three dimensions, whereas ministers with legislative backgrounds receive increased support only for interbranch coordination skills. The levels of support for ministers with different backgrounds also vary across agency types. This analysis has implications for public management practice and agency control in presidential governments.     

Climate Change and a Just Transition to the Future of Work

Rapidly growing concerns about the adverse effects of climate change are prompting a re-thinking of how companies view their strategies and operations and spurring legal and regulatory responses around the world. The overarching objective of these efforts is to facilitate and accelerate the transition to a more sustainable economy. The green transition will have substantial distributional and structural implications for workers and the workplace across companies and economic sectors. Indeed, the future of work will be significantly shaped by climate change. However, relatively scant scholarly attention has been devoted to the forward-looking legal implications of climate change for work. Similarly, legal scholars writing on climate change have largely neglected the laws governing employment. This article seeks to help fill that gap. How can companies, workers, and society respond to the green transition in a manner that enables better jobs, a safe and stable workplace, and more resilient companies? To answer this question, this article draws on the theory of just transition, which is rooted in environmental justice and labor rights. We offer an interpretation and application of just transition that expands its scope to serve as a blueprint for ethical business conduct and legal reform to improve the world of work and the lives of workers.     

Modified Midi‐ and Mini‐Multiplex PCR Systems for Mitochondrial DNA Control Region Sequence Analysis in Degraded Samples

Two multiplex polymerase chain reaction (PCR) systems (Midiplex and Miniplex) were developed for the amplification of the mitochondrial DNA (mtDNA) control region, and the efficiencies of the multiplexes for amplifying degraded DNA were validated using old skeletal remains. The Midiplex system consisted of two multiplex PCRs to amplify six overlapping amplicons ranging in length from 227 to 267 bp. The Miniplex system consisted of three multiplex PCRs to amplify 10 overlapping short amplicons ranging in length from 142 to 185 bp. Most mtDNA control region sequences of several 60‐year‐old and 400–500‐year‐old skeletal remains were successfully obtained using both PCR systems and consistent with those previously obtained by monoplex amplification. The multiplex system consisting of smaller amplicons is effective for mtDNA sequence analyses of ancient and forensic degraded samples, saving time, cost, and the amount of DNA sample consumed during analysis.
