A systematic review of risk management in innovation-oriented firms

Innovation and risk are inseparable. In fact, literature on innovation management often recommends that innovation-oriented firms must actively monitor, evaluate, analyze and treat future events in order to mitigate risks whenever possible. This approach is particularly important in emergent economies characterized by unstructured national innovation systems and constant economic and market instability. However, there has been no systematic effort to identify and categorize risks that potentially impact businesses based on innovation. Thus, we propose an interpretative framework of risk events with potential financial impact in innovation-oriented firms constructed and tested by means of a mixed studies review. The risk events were identified through a comprehensive systematic search and review of the published literature on risk and innovation. From the 115 works that were analyzed, it was possible to identify nine categories of risk events frequently associated with innovation-oriented businesses that may generate financial impacts. The proposed interpretative framework was tested in an empirical study with 13 innovation-oriented firms located in six Brazilian technological parks. Results from the empirical study suggest that managers found the proposed interpretative framework complete and comprehensive. Moreover, the empirical study signaled which risk events are more relevant for the Brazilian context. The proposed framework is a first necessary step for future development of ERM models applicable in innovation-intensive contexts.     

ESTABLISHMENT DYNAMICS,VACANCIES, AND UNEMPLOYMENT: A NEOCLASSICAL APPROACH

This article introduces and analyzes a Walrasian model of worker flows, job flows, vacancies, and unemployment. Calibrating the model to U.S. data, the article finds that all variables comove with output quite well but that they fluctuate too little. However, the failure is not as bad as in “Shimer's puzzle.” Interestingly, the article also finds that introducing establishment dynamics into the model, while realistic, is irrelevant for understanding unemployment and vacancy fluctuations: The business cycles of the model with establishment dynamics are virtually the same as those of a version with a representative firm.     

Implications of Monetary Union for Catching-up Member States

We examine the implications of monetary union for macroeconomic stabilization in catching-up participating countries. We allow member states’ supply conditions to differ, especially with regard to sectoral characteristics. Sectoral productivity shocks of the type associated with the Balassa–Samuelson effect tend to hamper the stabilization properties of a currency union. In the face of aggregate supply disturbances, the stabilization costs of renouncing monetary autonomy diminish with a steeper supply curve (as induced by higher trade openness) and—barring idiosyncratic shocks—with a larger reference country size, more homogeneous supply slopes and a higher preference for price stability.

Performance of conditional Wald tests in IV regression with weak instruments

We compare the powers of five tests of the coefficient on a single endogenous regressor in instrumental variables regression. Following Moreira [2003, A conditional likelihood ratio test for structural models. Econometrica 71, 1027–1048], all tests are implemented using critical values that depend on a statistic which is sufficient under the null hypothesis for the (unknown) concentration parameter, so these conditional tests are asymptotically valid under weak instrument asymptotics. Four of the tests are based on k-class Wald statistics (two-stage least squares, LIML, Fuller's [Some properties of a modification of the limited information estimator. Econometrica 45, 939–953], and bias-adjusted TSLS); the fifth is Moreira's (2003) conditional likelihood ratio (CLR) test. The heretofore unstudied conditional Wald (CW) tests are found to perform poorly, compared to the CLR test: in many cases, the CW tests have almost no power against a wide range of alternatives. Our analysis is facilitated by a new algorithm, presented here, for the computation of the asymptotic conditional p-value of the CLR test.     

On the cyclical behavior of employment, unemployment and labor force participation

In this paper I evaluate to what extent a real business cycle (RBC) model that incorporates search and home production decisions can simultaneously account for the observed behavior of employment, unemployment and out-of-the-labor-force. This contrasts with the previous RBC literature, which analyzed employment or hours fluctuations either by lumping together unemployment and out-of-the-labor-force into a single non-employment state or by assuming a fixed labor force. Once the three employment states are explicitly introduced I find that the RBC model generates highly counterfactual labor market dynamics.

The database described in this article provides researcherswith a broad set of data on trade, production, and protectionfor 28 manufacturing sectors at the three-digit level of theInternational Standard Industrial Classification, Revision 2.The database covers up to 100 developing and developed countriesover the period 1976–2004, but data availability variesby country and year. The trade, production, and protection databaseis available online and can be freely accessed through the WorldBank trade website.     

Effect of the use of social media in trust,loyalty and purchase intention in physical stores

This research evaluates the effect of the use of social media on consumer trust, loyalty and purchase intention in physical stores. We used six constructs in a structural model: a consumer’s use of social media, company-generated communication in social media, user-generated communication on social media, trust, loyalty and purchase intention. We considered 406 valid respondents in the analysis. The results suggest that the use of social media, company and user-generated communication positively affects trust of the physical store. Trust, in turn, has a direct positive effect on consumer loyalty to the store, and both trust and loyalty have positive impacts on a consumer’s purchase intention. We note the impact of the use of social media on purchase intention in physical stores, through the building of trust and loyalty with the store, as a fundamental element in the definition and implementation of a successful marketing strategy by high street retailers.
