Cost-effectiveness analysis in the Spanish setting of the PEAK trial of panitumumab plus mFOLFOX6 compared with bevacizumab plus mFOLFOX6 for first-line treatment of patients with wild-type RAS metastatic colorectal cancer

Objective: To assess the cost-effectiveness of panitumumab in combination with mFOLFOX6 (oxaliplatin, 5-fluorouracil, and leucovorin) vs bevacizumab in combination with mFOLFOX6 as first-line treatment of patients with wild-type RAS metastatic colorectal cancer (mCRC) in Spain.

Methods: A semi-Markov model was developed including the following health states: Progression free; Progressive disease: Treat with best supportive care; Progressive disease: Treat with subsequent active therapy; Attempted resection of metastases; Disease free after metastases resection; Progressive disease: after resection and relapse; and Death. Parametric survival analyses of patient-level progression free survival and overall survival data from the PEAK Phase II clinical trial were used to estimate health state transitions. Additional data from the PEAK trial were considered for the dose and duration of therapy, the use of subsequent therapy, the occurrence of adverse events, and the incidence and probability of time to metastasis resection. Utility weightings were calculated from patient-level data from panitumumab trials evaluating first-, second-, and third-line treatments. The study was performed from the Spanish National Health System (NHS) perspective including only direct costs. A life-time horizon was applied. Probabilistic sensitivity analyses and scenario sensitivity analyses were performed to assess the robustness of the model.

Results: Based on the PEAK trial, which demonstrated greater efficacy of panitumumab vs bevacizumab, both in combination with mFOLFOX6 first-line in wild-type RAS mCRC patients, the estimated incremental cost per life-year gained was €16,567 and the estimated incremental cost per quality-adjusted life year gained was €22,794. The sensitivity analyses showed the model was robust to alternative parameters and assumptions.

Limitations: The analysis was based on a simulation model and, therefore, the results should be interpreted cautiously.

Conclusions: Based on the PEAK Phase II clinical trial and taking into account Spanish costs, the results of the analysis showed that first-line treatment of mCRC with panitumumab?+?mFOLFOX6 could be considered a cost-effective option compared with bevacizumab?+?mFOLFOX6 for the Spanish NHS.     

Incentive Regulation and Telecommunications Service Quality

We examine the impact of incentive regulation—price regulation and earnings sharing regulation—on retail service quality in the U.S. telecommunications industry between 1991 and 2002. We find that incentive regulation is associated with significantly higher service quality on several dimensions (e.g., more rapid installation of new telephone service, fewer trouble reports, and increased customer satisfaction) but significantly lower quality on some dimensions (fewer installation commitments met and longer delays in resolving reported service problems)JEL Classification: L51, L96, L15We thank Michael Crew and two anonymous referees for helpful comments and suggestions.

Weak exogeneity in partially nonstationary models

This paper is dedicated to analysing the conditions for weak exogeneity in partially nonstationary models. After adopting a particular identification regime which is based on a triangularization of the parameters of the cointegration relations, we show that the conditions for weak exogeneity developed in the literature can be stated in terms of the parameters of the so-called structural form. This alternative presentation of the conditions permits new interpretations and provides fresh insights on how to test the exogeneity hypothesis.     

The Effectiveness of Capital Controls: Theory and Evidence from Chile

Selective capital controls tax only some components of capital flows. One of the rationales for such controls is that they increase the scope for an independent monetary policy, without taxing foreign direct investment and other long term flows. The first part of this paper offers a new framework to evaluate how selective capital controls might increase monetary autonomy, which considers two types of capital flows that coexist: the taxed and exempt flows. It is found that under free floating selective controls increase monetary autonomy, in the sense of allowing the authorities to set the path of the nominal exchange rate. But under predetermined exchange rate rules, the contribution of selective controls to monetary autonomy depends of the ability to reduce total inflows, which is an empirical matter. The second part describes the Chilean unremunerated reserve requirement (URR), a selective control introduced in June 1991 on a permanent basis, in a setting of predetermined exchange rates. This control collected substantial revenue, proving that it was relevant. An econometric model with data for 1987–1996 finds that substitution from the exempt short-term flows compensated reductions in taxed short-term flows, so the Chilean URR did not discourage total net short-term credit inflows to the private sector. This implies that the Chilean URR failed to contribute to monetary autonomy.     

Toward a conceptual framework of the harmonization of bank financial reporting standards in transition economies: The case of Mexico

In recent years banks in emerging and transition economies throughout the world have been compelled to change lending and financial reporting practices in response to the economic transition of their countries. Correspondingly, on the basis of the theory of soft budget constraints (SBC), economists have studied the relationship between economic development, banks' lending practices, and banks' penchant to overstate loans. However, very little research has been performed by accounting researchers regarding the nature of bank loan overstatement during times of financial crisis in emerging markets. Accordingly, this paper uses the theory of soft budget constraints to develop a four stage conceptual framework of the harmonization of bank financial reporting standards during times of economic transition. Emphasis is placed on using the theory of soft budget constraints to characterize the harmonization of standards and practices with respect to bank loan overstatement. The framework is applied to the harmonization of Mexican bank financial reporting during the country's economic transition of the late 1990s. The Mexican harmonization process during this period generally followed the framework.     

Implementability via protective equilibria

We present a notion of non-cooperative strategic equilibrium for games generated by social choice functions, and fully characterize the class of those functions which are directly implementable under this equilibrium concept. Correct preference revelation turns out to always be such an equilibrium for the games generated by this class of implementable functions.     

Incentive compatible reward schemes for labour-managed firms

We consider a simple case of team production, where a set of workers have to contribute a single input (say labour) and then share the joint output amongst themselves. Different incentive issues arise when the skills as well as the levels of effort expended by workers are not publicly observable. We study one of these issues in terms of a very simple model in which two types of workers, skilled and unskilled, supply effort inelastically. Thus, we assume away the problem of moral hazard in order to focus on that of adverse selection. We also consider a hierarchical structure of production in which the workers need to be organised in two tiers. We look for reward schemes which specify higher payments to workers who have been assigned to the top-level jobs when the principal detects no lies, distribute the entire output in all circumstances, and induce workers to revel their true abilities. We contemplate two scenarios. In the first one, each individual worker knows only her own type, while in the second scenario each worker also knows the abilities of all other workers. Our general conclusion is that the adverse selection problem can be solved in our context. However, the range of satisfactory reward schemes depends on the informational framework.
