<p>This thesis develops a model that investigates aspects of New Zealand’s largest public-private partnership project, the rollout of Ultra Fast Broadband. The model features four cities with different demand and construction-cost characteristics. It is used to study the different choices of the private party (Chorus) and the public party (Crown Fibre Holdings (CFH)). Using a real options approach, we identify two sorts of potential conflicts between the two parties: a timing conflict about the number of cities the two parties would like to develop in each period and a sequencing conflict about the order in which the UFB network is rolled out in different cities. Inspired by the incomplete contracting and information asymmetry literatures, we introduce several incentive schemes (including four subsidy schemes and two fine schemes) that help manage the possible conflicts. We compare both their ability to reduce the conflicts and their sensitivity to the model’s underlying parameters. Overall, there are four main findings. First, the magnitude of the conflict is a non-monotonic function of the inter-city demand differences and the inter-city construction-cost differences; it is an increasing function of the ratio of consumer surplus to producer surplus and of demand volatility. Second, a demand-dependent lump sum subsidy has the best performance among all included incentive schemes in controlling the possible conflicts. Third, the conflict level becomes quite sensitive to the subsidy scheme in two cases. A) When either the inter-city demand differences or the inter-city construction-cost differences turn out to be modest; B) When either the ratio of consumer surplus to producer surplus or demand volatility turns out to be large. The above result may provide some suggestions in managing the optimal subsidy. Last but not least, the requirement that Chorus is willing to participate in the partnership means that the fine schemes are generally outperformed by the subsidy schemes. Relating our findings to the undertaking UFB project, we provide CFH with several practical suggestions that may improve its management of possible conflicts.</p>

In this article, the global simulation model (GSIM) of Joseph F. Francois and Keith H. Hall (2009) for analyzing global, regional, and unilateral trade policy changes was applied to Serbia. This was to measure the effects of full trade liberalization with the EU after Serbian accession to the EU. As anticipated, most of the changes in welfare after full liberalization of trade between Serbia and EU can be expected in sectors where Serbia has specialized; protection against imports from the EU is strong. However, losses could also occur in sectors that currently face strong protection against the rest of the world and this protection is lost after EU accession. Trade liberalization will lead to a substantial loss of tariff revenues. Reduced consumer prices might, on the one hand increase consumer surplus but on the other hand decrease producer surplus and output in certain industries.

Displacement Model

Using survey data and an equilibrium displacement model, we estimate the market and economic impacts of the American Forest and Paper Association's Sustainable Forestry Initiative (SFI) on stumpage markets in the US South. We examine four timber product markets: softwood pulpwood, softwood sawtimber, hardwood pulpwood, and hardwood sawtimber. In each market we calculate changes in producer and consumer welfare using the equilibrium displacement model that accounts for reductions in timber inventories caused by SFI compliance. We find that SFI compliance costs the US South's economy about $36 million annually. SFI-compliant stumpage producers lose more than $33 million each year in producer surplus as a result of SFI compliance, and consumers lose about $12 million annually in consumer surplus due to higher product prices. These costs are offset partially by benefits to nonindustrial private forest producers, non-SFI-compliant industry producers, and public forest producers, who collectively gain about $10 million in producer surplus annually as a result of higher stumpage prices.

Strong Linear Relationship

Refurbishing buildings helps reduce waste, and limiting the amount of embodied carbon in buildings helps minimize the damaging impacts of climate change through lower CO2 emissions. The analysis of embodied carbon is based on the concept of life cycle assessment (LCA). LCA is a systematic tool to evaluate the environmental impacts of a product, technology, or service through all stages of its life cycle. This study investigates the embodied carbon footprint of both new-build and refurbished buildings to determine the embodied carbon profile and its relationship to both embodied energy and construction cost. It recognizes that changes in the fuel mix for electricity generation play an important role in embodied carbon impacts in different countries. The empirical findings for Hong Kong suggest that mean embodied carbon for refurbished buildings is 33–39% lower than new-build projects, and the cost for refurbished buildings is 22–50% lower than new-build projects (per square meter of floor area). Embodied carbon ranges from 645–1059 kgCO2e/m2 for new-build and 294–655 kgCO2e/m2 for refurbished projects, which is in keeping with other studies outside Hong Kong. However, values of embodied carbon and cost for refurbished projects in this study have a higher coefficient of variation than their new-build counterparts. It is argued that it is preferable to estimate embodied energy and then convert to embodied carbon (rather than estimate embodied carbon directly), as carbon is both time and location specific. A very strong linear relationship is also observed between embodied energy and construction cost that can be used to predict the former, given the latter. This study provides a framework whereby comparisons can be made between new-build and refurbished projects on the basis of embodied carbon and related construction cost differentials into the future, helping to make informed decisions about which strategy to pursue.

IntroductionWe estimate the life-cycle value of risperidone – Second-Generation Antipsychotics (SGA) – to balance the view that cost per Quality-Adjusted Life Year (QALY) estimates at launch are enough to guide access decisions. Study results will also drive discussion on access and price to recognize the dynamic nature of pharmaceutical pricing over the long-run.MethodsWe estimated number of patients treated for schizophrenia with risperidone in Sweden and the United Kingdom (UK) between 1994-2017 based on usage data form national statistics and volume sales data from IQVIA. We collected data from literature on the effectiveness (QALYs) and costs (EUR 2017) of risperidone (SGA) and haloperidol – First-Generation antipsychotic (FGA). We estimate the life-cycle value added by risperidone versus haloperidol, and the life-cycle distribution of the social surplus between the payer (consumer surplus) and the innovator (producer surplus).ResultsWe estimated the consumer surplus, the producer surplus, the Net Monetary Benefit (NMB) and Incremental Cost-Effectiveness Ratio (ICER) at each year and in aggregate terms (1993-2017). For the UK the producer surplus was ~28 percent out of the total surplus before patent expiration and five percent after patent expiration. In Sweden, producer surplus was around 6 percent out of the total surplus before patent expiration and one percent thereafter. In both countries, during the life-cycle of risperidone, the NMB per patient increased and the ICER decreased as a response to: (i) the launch of Risperidone Long-Acting Injectable (RLAI); and (ii) the generic entry.ConclusionsThe value added by risperidone increased during the life-cycle due to the launch of RLAI and the generic competition. This suggests that, considering the entire life-cycle, the value added by SGAs to the system is higher than the expected value estimated using cost-effectiveness analysis at launch. Pricing and reimbursement decisions should take into account the dynamic nature of pharmaceutical markets and the value added by innovative medicines over the long-run.

Under the North American Free Trade Agreement (NAFTA) tariffs on U.S. potato imports to Mexico were phased out by 1993. Citing phytosanitary issues, in 1996, the Mexican government placed quantitative restrictions on U.S. potato imports and restricted their import only to designated border areas. This article estimates the welfare cost of restricting U.S. potato imports into Mexico. We find that removing trade restrictions may lead to over 1.8 million tons of new imports into Mexico, a gain of consumer surplus of 4.0 billion pesos per year, and a loss of 2.9 billion pesos of producer surplus.

This study was designed to evaluate the welfare effect of the climate adaptation policy for rice price variation in terms of producer surplus, consumer surplus, and net change in social welfare in Bangladesh, using the partial equilibrium model of the adaptation policy. The long-term trend of climate and policy adaptation for climate impact on price variation of the rice in Bangladesh is taken into economic model approach. The base period of this research is 1977-2009 and the extrapolation period is 2010-2030. To execute the designed analysis, the time series data from national and international organization are used. The results for the support price policy show that the total surplus that producers receive is equivalent to USD 1,164 million, substantially higher than the consumer surplus (USD 763 million) during the period 2010–2030. The net change in the social welfare owing to the support price policy is equivalent to –1483 million (USD) during the period 2010–2030. Moreover, analysis of the subsidized price policy shows that the total surplus that consumers receive (USD 1,958 million) is relatively higher than the producer surplus (USD 1,738 million) in the same period. The net change in social welfare owing to the subsidized price policy (–197 million USD) is much higher than that owing to price support –1483 million (USD). Implementing the dual price policy would result in a much higher net change in the society’s welfare (–1185 million USD) compared to that possible through each policy separately. In conclusion, these adaptation and price stabilization policies are recognized to be more useful in mitigating the severe price rise and fall in the future food market, in favour of both producers and consumers. Even though the change in net social welfare is higher, the higher cost of policy budget is imperative to make stable food supply and security.
