Implementation Delay

We study investment and disinvestment decisions in situations where there is a time lagd> 0 from the timetwhen the decision is taken to the timet+dwhen the decision is implemented. In this paper we apply the probabilistic approach to the combined entry and exit decisions under the Parisian implementation delay. In particular, we prove the independence between Parisian stopping times and a general Brownian motion with drift stopped at the stopping time. Relying on this result, we solve the constrained maximization problem, obtaining an analytic solution to the optimal ‘starting’ and ‘stopping’ levels. We compare our results with the instantaneous entry and exit situation, and show that an increase in the uncertainty of the underlying process hastens the decision to invest or disinvest, extending a result of Bar-Ilan and Strange (1996).

Implementation Delay

ObjectivesIn 2012, Australia was the first country in the world to introduce plain or standardised tobacco packaging, coupled with larger graphic health warnings. This policy was fiercely opposed by industry. Media coverage can be an influential contributor to public debate, and both public health advocates and industry sought media coverage for their positions. The aim of this study was to measure the print media coverage of Australian’s plain packaging laws, from inception to roll-out, in major Australian newspapers.MethodsThis study monitored mainstream Australian print media (17 newspapers) coverage of the plain packaging policy debate and implementation, over a 7-year period from January 2008 to December 2014. Articles (n=701) were coded for article type, opinion slant and topic(s).DesignContent analysis.ResultsCoverage of plain packaging was low during preimplementation phase (2008–2009), increasing sharply in the lead into legislative processes and diminished substantially after implementation. Articles covered policy rationale, policy progress and industry arguments. Of the news articles, 96% were neutrally framed. Of the editorials, 55% were supportive, 28% were opposing, 12% were neutral and 5% were mixed.ConclusionsProtracted political debate, reflected in the media, led to an implementation delay of plain packaging. While Australian media provided comprehensive coverage of industry arguments, news coverage was largely neutral, whereas editorials were mostly supportive or neutral of the policy. Countries seeking to implement plain packaging of tobacco should not be deterred by the volume of news coverage, but should actively promote the evidence for plain packaging in the media to counteract the arguments of the tobacco industry.

AbstractWe study optimal stopping of strong Markov processes under random implementation delay. By random implementation delay we mean the following: the payoff is not realised immediately when the process is stopped but rather after a random waiting period. The distribution of the random waiting period is assumed to be phase-type. We prove first a general result on the solvability of the problem. Then we study the case of Coxian distribution both in general and with scalar diffusion dynamics in more detail. The study is concluded with two explicit examples.

Stepped Wedge Trial

Evidence-based policy is limited by the perception that randomized controlled trials (RCTs) are expensive and infeasible. We argue that carefully tailored research design can overcome these challenges and enable more widespread randomized evaluations of policy implementation. We demonstrate how a stepped-wedge (randomized rollout) design that adapts synthetic control methods overcame substantial practical, administrative, political, and statistical constraints to evaluating King County’s new food safety rating system. The core RCT component of the evaluation came at little financial cost to the government, allowed the entire county to be treated, and resulted in no functional implementation delay. The case of restaurant sanitation grading has played a critical role in the scholarship on information disclosure, and our study provides the first evidence from a randomized trial of the causal effects of grading on health outcomes. We find that the grading system had no appreciable effects on foodborne illness, hospitalization, or food handling practices but that the system may have marginally increased public engagement by encouraging higher reporting.

Sea transportation is seen as the most effective means of responding to the high demand for a commodity. The development of industry 4.0 and society 5.0 has a big influence on the economic growth of a country. Loading and unloading must go well, so efforts are needed to ensure its implementation. Delay in unloading due to hydraulic leakage. The captain and guard officer as more experienced parties are expected to make efforts to prevent it. Coordinating work when unloading shows that the ship has followed procedures and efforts to repair hydraulic leaks. The method used by researchers to analyze problems is the fishbone analysis method. Research data obtained from primary data and secondary data, while data collection was obtained from observations, interviews, descriptive and literature. Fishbone analysis aims as an effort made to change the data from the results of a study into simpler information, so that it is easy to use to draw conclusions. Based on the results of this study, hydraulic maintenance was further improved and procurement of spare parts continued to be pursued by the ship. In addition, the company's management also affects the performance of the crew on the ship so that there is a need for improvement in the company's management of the ship.
