Estimated Open Economy New Keynesian Phillips Curves for the G7

In this paper we develop an open economy model of firms’ pricing behaviour under imperfect competition. This allows us to introduce various terms of trade effects influencing the firm’s pricing decision, in addition to labour costs which dominate most closed-economy specifications of the New Keynesian Phillips curve (NKPC). Our analysis gives rise to a hybrid open economy NKPC which nests existing closed and open economy specifications adopted in empirical work. We estimate this specification for the G7 economies and find that the US, UK and Canada typically enjoy less inertia in price setting than the European G7 economies and Japan and that these estimates are both plausible and in line with survey evidence. We also find that the proportion of firms which use simple backward-looking rules of thumb in price setting is greater when the frequency of price change is smaller. Finally there is evidence of significant asymmetries in price setting amongst EMU members.

Does the sequencing of related and unrelated export diversification matter? Evidence from Colombian exporters

How does related or unrelated geographic diversification affect future related or unrelated product diversification of exporting firms, and vice-versa? This question addresses an unresolved debate, and it is important for firms in developing countries that seek to expand their product and geographical markets. Our study contributes to a current debate by highlighting the relevance of the temporal sequence and the relatedness of international diversification. Expanding the classic transaction costs and the resource-based explanations, we argue that organizational learning as well as organizational and sales (in-)efficiencies (notably through resource and product cannibalization, negative transfer and coordination costs) affect the interrelationships between product and geographic diversification. Using a panel dataset of over 14,000 firm-year observations from exporters based in Colombia, we find that (1) related geographic diversification tends to increase future product diversification; (2) related product diversification tends to decrease future geographic diversification; and (3) unrelated product diversification tends to increase future geographic diversification.

Family farmers' strategies to develop autonomy through agroecological and solidarity economy practices: The case of BioVida in the Ecuadorian Andes

Considering the global restructuring affecting agrarian landscapes, we build on the concept of autonomy proposed by van der Ploeg and colleagues (but extended and critically complemented) to analyse how family farmers can build this autonomy to face rural capitalist tendencies and maintain their activities and identity. We offer insights from a case study in the Ecuadorian Andes, the BioVida organization that is linked to agroecological and social and solidarity economy movements. Our findings show that family farming autonomy is not being achieved homogeneously for the whole household but must be analysed through an intersectional approach. Furthermore, there are simultaneous processes to achieve different degrees of autonomy and (inter-)dependency, which are co-constitutive along gender and age lines and are conditioned by structural constraints. Therefore, for our case study area, agribusiness and family farming processes and spaces seem to operate co-constitutively rather than antagonistically in practical terms. Agroecology-based achievements so far act as a localized buffer against adversity rather than an emancipative territorial project of autonomy.     

Understanding China's Economic Growth from a Regional Policy Perspective

There has been ongoing interest in China's economic growth. What were the drivers of China's economic growth in past years? What policies were used to promote China's economic growth? Although different lenses may be used to understand and explain China's economic growth, this paper draws on historical, theoretical, and empirical perspectives to discuss the nexus between China's regional policies and economic growth. First, we review the evolution of China's regional policy and the policy's changing emphasis in different development stages, from balanced, unbalanced, and coordinated development to synergistic development. Then we construct a theoretical model to illustrate the impact of regional policy on the local economy and conduct an empirical examination with a case study of regional policy using regression discontinuity design. This paper analyzes the concept of regional policy and the underpinning logic of economic growth and presents practical approaches to formulate a better regional policy framework.     

A warm welcome for destination quality brands: the example of the Pays Cathare region

In this paper, the salient complexities characterising quality management at the tourism destination are outlined, and in light of these, a number of quality principles are deemed particularly appropriate for the further investigation of destination quality management (DQM). The complexities include the significant number of services provided at the destination, the highly fragmented nature of the tourism destination product and the large number of small businesses that go to comprise this product. General principles are drawn from the SERVQUAL, Kano and EFQM Business Excellence models in order to provide a tentative framework for investigating how one destination has striven to overcome these challenges. The example of the Pays Cathare Region in southern France, which has been recognised by the European Commission as an example of best practice in integrated quality management (IQM), shows how these quality tenets can be translated from the theoretical framework into actual practice by means of its destination quality brand.
