Storing radiology images in the reform era: what CFOs need to know

Vendor-neutral archives (VNAs) normalize PACS images and make image exchange possible, even when multiple divergent PACS or radiology departments are involved. These systems, onsite or cloud-based, allow for strategic and long-term growth regardless of the PACS used. Radiologists continue to operate with their system/vendor of choice, further strengthening productivity, satisfaction, and organizational loyalty. Finance executives shave costs, avoid future PACS expenses, and gain greater leverage with PACS vendors.     

The market price of fiscal uncertainty

Recent fiscal interventions have raised concerns about US public debt, future distortionary tax pressure, and long-run growth potential. We explore the long-run implications of public financing policies aimed at short-run stabilization when: (i) agents are sensitive to model uncertainty, as in Hansen and Sargent (2007), and (ii) growth is endogenous, as in Romer (1990). We find that countercyclical deficit policies promoting short-run stabilization reduce the price of model uncertainty at the cost of significantly increasing the amount of long-run risk. Ultimately these tax policies depress innovation and long-run growth and may produce welfare losses.     

Rethinking ‘Top‐Down’ and ‘Bottom‐Up’ Roles of Top and Middle Managers in Organizational Change: Implications for Employee Support

In this study we integrate insights from ‘top‐down’ and ‘bottom‐up’ traditions in organizational change research to understand employees’ varying dispositions to support change. We distinguish between change initiation and change execution roles and identify four possible role configurations in which top managers (TMs) and middle managers (MMs) can feature in change. We contend that both TMs and MMs can play change initiation and/or change execution roles, TMs and MMs have different strengths and limitations for taking on different change roles, and their relative strengths and limitations are compounded or attenuated based on the specific configuration of change roles. We subsequently hypothesize employee support for change in relation to different TM‐MM change role configurations. Our findings show that change initiated by TMs does not engender above‐average level of employee support. However, change initiated by MMs engenders above‐average level of employee support, and even more so, if TMs handle the change execution.     

The Effects of IFRS Adoption on the Unconditional Conservatism of Spanish Listed Companies

This paper analyses the effects of the mandatory adoption of International Financial Reporting Standards (IFRS) by Spanish listed companies in January 2005 on unconditional conservatism. The lack of robustness in previous evidence justifies analysis of this issue from a different perspective. To this end, we use, for the first time in this context, Ahmed and Duellman's (2007) methodology. These authors consider the impact of growth options and other future income, controlling for the idiosyncratic factors that the literature has found condition this type of conservatism. Additionally, beyond the pooled regression techniques usually used, we use econometric panel data techniques, which minimise the possible effect of endogeneity in the estimation of the proposed models. The results provide new evidence which supports our hypothesis that the adoption of IFRS has reduced the unconditional conservatism of Spanish listed companies.     

Rockets and feathers: Understanding asymmetric pricing

Prices rise like rockets but fall like feathers. This stylized fact of many markets is confirmed by many empirical studies. In this article, I develop a model with competitive firms and rational partially informed consumers where the asymmetric response to costs by firms emerges naturally. In contrast to public opinion and past work, collusion is not necessary to explain such a result.     

As times goes by. A dynamic impact assessment of the innovation policy and the Matthew effect on Argentinean firms

ABSTRACT

The objective of this paper is to analyse the impact of public funds for innovation on firm’s capabilities, innovative dynamics and economic performance. A large stream of literature about the evaluation of public funds is focused on testing the existence of additionality effects on investments and results. This paper aims to provide evidence about other dimensions of the firm that public policy can alter, with focus on the time window between the treatment and the impact, and the role of the Matthew effect (recurrence) in this process. The empirical exercise is based on a dynamic panel data made of 1465 firms (3337 observations) that applied to the Argentinean Technological Fund (FONTAR), which is the main public fund for innovation in Argentina, between 2007 and 2016. Results show short-term effects of accessing to FONTAR on firms’ capabilities, medium-term effects on innovation efforts and long-term effects on productivity. Even though the effect on productivity is larger among recurrent firms, the differences among recurrent and non-recurrent firms are not conclusive in case of capabilities and innovation efforts. All in all, this research provides evidence about the ‘when’ of public policy and the need to look beyond input additionality effects when analysing its impact.     

The effects of domestic rice market interventions outside business-as-usual conditions for imported rice prices

The Philippine government intervenes in the domestic rice market through the imposition of import tariffs and the provision of producer and consumer subsidies. While policymakers are aware that these programmes come with allocative efficiency costs, they justify the programmes on the grounds that they insulate the domestic economy from unexpected price spikes in the international rice market. An interesting matter for policy evaluation is to quantify the insulation benefit that the programmes provide in circumstances of sudden severe import price spikes. To examine this question, we undertake a dynamic computable general equilibrium (CGE) simulation in which the Philippines is subject to an external rice price shock. We find that the insulation benefit of the support programmes under a 2008-like event is worth approximately 0.10% of real consumption. However, the cost of insuring against these price spikes is significant. We estimate the annual cost of the rice market interventions at approximately 0.40% of real consumption.     

Statistical tests for multiple forecast comparison

We consider a multivariate version of the Diebold–Mariano test for equal predictive ability of three or more forecasting models. The Wald-type test, $S$, which has a null distribution that is asymptotically chi-squared, is shown to be generally invariant with respect to the ordering of the models being compared. Finite-sample corrections for the test are also developed. Monte Carlo simulations indicate that $S$ has reasonable size properties in large samples but tends to be oversized in moderate samples. The finite-sample correction succeeds in correcting for size, but only partially. For the size-adjusted tests, power increases with sample size, as expected. It is speculated that further finite-sample improvements can be achieved using Hotelling’s $T^2$ or bootstrap critical values.     

Long-term interest rates,risk premia and unconventional monetary policy

We study two kinds of unconventional monetary policies: announcements about the future path of the short-term rate and long-term nominal interest rates as operating instruments of monetary policy. We do so in a model where the risk premium on long-term debt is, in part, endogenously determined. We find that both policies are consistent with unique equilibria, that, at the zero lower bound, announcements about the future path of the short-term rate can lower long-term interest rates through their impact both on expectations and on the risk premium and that long-term interest rate rules perform as well as, and at times better than, conventional Taylor rules. With simulations, we show that long-term interest rate rules generate sensible dynamics both when in operation and when expected to be applied.
