Using the Reinhart–Rogoff dataset, we find a debt threshold not around 90 per cent but around 30 per cent, above which the median real gross domestic product (GDP) growth falls abruptly. Our work is the first to formally test for threshold effects in the relationship between public debt and median real GDP growth. The null hypothesis of no threshold effect is rejected at the 5 per cent significance level for most cases. While we find no evidence of a threshold around 90 per cent, our findings from the post‐war sample suggest that the debt threshold for economic growth may exist around a relatively small debt‐to‐GDP ratio of 30 per cent. Furthermore, countries with debt‐to‐GDP ratios above 30 per cent have GDP growth that is 1 percentage point lower at the median. 相似文献

In this article, we propose a new framework for addressing multivariate time-varying volatilities. By employing methods of differential geometry, our model respects the geometric structure of the covariance space, i.e., symmetry and positive definiteness, in a way that is independent of any local coordinate parametrization. Its parsimonious specification makes it particularly suitable for large dimensional systems. Simulation studies suggest that our model embraces much of the nonlinear behaviour of the covariance dynamics. Applied to the US and the UK stock markets, the model performs well, especially when applied to risk measurement. In a broad context, our framework presents a new approach treating nonlinear properties observed in the financial market, and numerous areas of application can be further considered. 相似文献

We provide evidence consistent with the notion that prudent use of financial derivatives improves firms’ information environment. We show that firms with sophisticated and comprehensive derivatives use policies display lower levels of uncertainty about future cash flows, volatility of future income and sales growth, and equity mispricing than those that do not use derivatives. However, we also show that policies that consist of large positions in a single type of derivative contract are not likely to produce similar benefits. These results remain intact even after accounting for the endogenous nature of derivatives use policy and information risk and mispricing. 相似文献

In this paper, we examine the role of export promotion agencies (EPAs) in promoting exports from Japan and Korea. Looking at two home countries enables us to tackle endogeneity issues by controlling for both country‐pair time‐invariant characteristics and importing‐country time‐varying characteristics. Our empirical results indicate that EPA has a positive and significant effect on exports even when we control for endogeneity. However, the size of the effect becomes substantially smaller, implying the importance of addressing endogeneity in accurately measuring the impact of EPA on exports. In addition, we find that EPA's (marginal) effects are larger in exporting to low‐income trade partners than in exporting to high‐income trade partners. 相似文献

This paper examines two interrelated questions: to what extent does coopetition in a firm's alliance portfolio impact the firm's innovation performance? And to what extent does a firm's coopetition experience influence the relationship between coopetition in the alliance portfolio and innovation performance? Conceptually, we advance the concepts of balanced coopetition in a firm's alliance portfolio and coopetition experience and suggest that both balanced coopetition and coopetition experience contribute to firm's innovation outcomes. Results based on a longitudinal data of firms from the semiconductor industry show that moderate to high levels of balanced-strong coopetition in a firm's alliance portfolio positively impact the firm's coopetition-based innovation performance. Further, coopetition experience contributes to innovation performance and positively moderates the relationship between balanced-strong coopetition and innovation performance. 相似文献

This note studies exchange rate pass-through to the prices of domestically produced goods, exploring the firm-level pricing survey conducted by the Bank of Korea. The data reveal the imported inputs channel of, as well as nonlinear and asymmetric, exchange rate-pass-through. 相似文献

We extend the knowledge‐based view with a new typology and its application to post‐IPO firm performance. The typology categorizes knowledge development activity along the dimensions of familiarity (whether the firm has experience with the knowledge or it is new) and source (whether the firm creates it independently or with partners). We use this typology to determine direct and interaction effects of knowledge development activity on survival, RoA, and Tobin's q of newly public firms. Using a sample of 1,056 high‐technology manufacturing IPOs in 1990–2005, we find that focused, internal knowledge development correlates with higher performance. We also find a positive interaction effect in combining focused, internal and diversifying, alliance‐based knowledge development, and a negative interaction effect in combining diversifying, internal and alliance‐based knowledge development.

We investigate how the second-order learning process moderates the relationship between innovation performance and two types of knowledge seeking behavior, namely exploration and exploitation. We reinvestigate the second-order learning process of the top 100 Korean firms from 1997 to 2007 by capturing CEO turnover, board turnover, and R&D alliances. We argue that the current findings about exploration and exploitation should be reclassified in terms of innovation input and output. We suggest that researchers investigate the organizational learning process to understand the link between innovation inputs and outputs. Our empirical results show that while innovation inputs are not related to exploratory outputs, the second-order learning process reshapes the relationship between both exploration/exploitation type innovation inputs and exploratory innovation outputs, and that the new focus of organizational learning process can refine current innovation literature. 相似文献

In this paper, we explore partial identification and inference for the quantile of treatment effects for randomized experiments. First, we propose nonparametric estimators of sharp bounds on the quantile of treatment effects and establish their asymptotic properties under general conditions. Second, we construct confidence intervals for the bounds and the true quantile by using the approach in Chernozhukov et al. (2009). Third, under additional conditions, we develop a new approach to construct confidence intervals for the bounds and the true quantile and refer to it as the order statistic approach. A simulation study is conducted to investigate the finite sample performance of both approaches. 相似文献

We analyze in this paper the asymptotic behavior of the specification test of Aït-Sahalia (1996) for the stationary density of a diffusion process, but when the diffusion is not stationary. We consider integrated and explosive processes, as well as nearly integrated ones in the spirit of the local to unity analysis in classical unit root theory. We find that the behavior of the test predicted by the asymptotic distribution under an integrated process provides a better approximation to the small sample distribution of the test than that predicted by the asymptotic distribution under strict stationarity. 相似文献
