Abstract

Purpose

In general, it is believed that firms belonging to the high technological intensity stratum have a more innovation capability. However, evidence has begun to appear in the literature demonstrating that firms in the low-tech stratum also have the innovation capability. This paper seeks to solve this dilemma. Through an analysis of industrial firms in an emerging country, this study aims to identify the existence of innovation capability in all strata of technological intensity.

Design/methodology/approach

The authors empirically assessed the impact of innovation capability on the performance of firms in all strata of technological intensity. The authors studied a sample of 910 firms from different industries and technology intensities operating in Peru, by applying a partial least squares structural equation model (PLS-SEM).

Findings

This study obtained three important findings. First, the authors show that innovation capability is present in all strata of technological intensity. Second, innovation capability differs according to the technological stratum. Third, firms in the lowest technological stratum can use more capabilities than those in the other strata.

Originality/value

This study pioneers the empirical analysis of innovation capability and technological intensity simultaneously to verify that innovation capability exists in the four strata of technological intensity.

This study focuses on how China EPU may impact copper-firms stock returns and also how China EPU mediates between stock returns and copper prices returns.

Abstract

Purpose

This study focuses on how China EPU may impact copper-firms stock returns and also how China EPU mediates between stock returns and copper prices returns.

Design/methodology/approach

The sample consists of 44 copper firms from January 2011 to March 2022. The study also considers a subsample of 29 net-exporters countries. Panel data methodology is used, allowing to control for unobservable heterogeneity and endogeneity problems. The equations are estimated through a dynamic panel using the generalized methods of moments (GMM).

Findings

China EPU has a negative and statistically significant relationship with stock returns. Copper price returns are positively associated with stock returns. This research also considers two scenarios: high and low levels of China EPU. For high levels of China EPU states it is reported a negative relationship between stock returns and China EPU and copper price returns show a positive relationship with stock returns.

Research limitations/implications

There is need to explore other metals for what China exhibits a high demand and observe if China EPU and Global EPU have similar impacts on stock returns. It will be useful to identify main firm's consumers of copper and these other metals to explore the relationship between EPU and stock returns.

Originality/value

To the best of the authors’ knowledge, this is the first paper that analyzes China EPU index and its impact on both copper-firms stocks returns and on changes in copper prices. This is done using all public copper firms worldwide.

Propósito

Este estudio se enfoca en como la incertidumbre en política económica de China (llamado China EPU) puede impactar en los retornos de las acciones de empresas del sector del cobre y como China EPU media entre los retornos de las acciones y los retornos de los precios del cobre.

Diseño/metodología/enfoque

La muestral consiste en 44 firmas de cobre desde enero 2011 a marzo 2022. El estudio también considera una sub muestra de 29 países que son exportadores netos de cobre. Se utiliza la metodología de datos de panel, permitiendo controlar por lo inobservable y por problemas de endogeneidad. Las ecuaciones son estimadas a través de panel dinámico usando el método generalizado de los momentos (G.M.M.).

Resultados

EPU de China tiene una relación negativa y estadísticamente significativa con los retornos accionarios. Los retornos de los precios del cobre están positivamente asociados con los retornos accionarios. La investigación también considera dos posibles escenarios: altos y bajos niveles de EPU. Para el estado de altos niveles se reporta una relación negativa entre los retornos accionarios y el EPU de China, además los retornos de los precios del cobre muestran una relación positiva con los retornos accionarios.

Limitaciones de la Investigación/Implicancias

Se requiere explorar otros metales para los cuales China sea un importante demandante a nivel internacional y observar si el EPU de China y el EPU Global tienen similares impactos en los retornos accionarios. A su vez sería útil identificar las principales firmas consumidoras de cobres y estos otros metales de tal forma de chequear la relación entre EPU y retornos accionarios.

Originalidad/valor

En nuestro mejor conocimiento, este es el primer artículo que analiza el índice EPU de China y como este impacta tanto los retornos accionarios de las empresas de cobre como los cambios de precios del cobre. Esto es hecho usando una muestral que incluye todas las empresas de cobre que se transan en bolsa a nivel internacional.
