This paper explores the determinants of start-up size by focusing on a cohort of 6,247 businesses that started trading in 2004, using a unique dataset on customer records at Barclays Bank. Quantile regressions show that prior business experience is significantly related with start-up size, as are a number of other variables such as age, education and bank account activity. Quantile treatment effects (QTE) estimates show similar results, with the effect of business experience on (log) start-up size being roughly constant across the quantiles. Prior personal business experience leads to an increase in expected start-up size of about 50 %. Instrumental variable QTE estimates are even higher, although there are concerns about the validity of the instrument.  相似文献

The development of the wind energy sector is often promoted as a means of supporting rural economies. This paper focuses on how the ownership structure of on‐shore wind power plants (external, farmer or community) affects the size and distribution of impacts within the rural part of a region. Empirical analysis is based on a regional computable general equilibrium model of North East Scotland with the results compared to those generated from a standard social accounting matrix multiplier analysis. With no local ownership, while rural GDP increases, there is almost no effect on household incomes due to the limited direct linkages of the on‐shore wind sector. Local ownership increases the household income benefits but there are still limited positive spill‐over effects on the wider economy unless factor income is re‐invested in local capital. With re‐investment, farm household ownership gives rise to the largest increase in total household income but community ownership gives rise to the largest increase in rural (non‐farm) household incomes and welfare. The results contribute to the on‐going debate about the opportunity cost of external asset ownership in rural areas.  相似文献

ABSTRACT

Many firms are developing virtual customer environments (VCEs) that provide customers the opportunity to submit, discuss, and vote for new ideas. Some studies show that VCEs promote the development of incremental improvements in existing products and services (i.e., exploitative innovation). However, other studies find that customers working in VCEs will often suggest radical ideas for brand new products and services (i.e., exploratory innovation). Exploration and exploitation are often incompatible; thus, we address this paradox by investigating whether the design of a firm’s VCE architecture is related to the firm’s exploratory innovation activity and exploitative innovation activity. Using matched data collected from VCEs and managers, we show that two-way information exchange VCE tools facilitate exploratory innovation, and one-way information exchange VCE tools enhance exploitative innovation. We also find that absorptive capacity positively moderates the latter relationship. Our findings have implications for research and practice in VCEs, organizational innovation, and organizational learning.  相似文献

This paper considers interactions between China's domestic and external imbalances and their global implications. We present scenarios detailing how a rebalancing of China's growth pattern from investment‐driven growth towards more consumption‐driven growth may occur in practice. Using input–output tables for 2012, we illustrate the knife‐edged nature of Chinese rebalancing, the linkages between expenditure‐side and production‐side rebalancing, and how an internal rebalancing could exacerbate external imbalances. A policy implication for China is that for rebalancing to be fast, consumption must be exceptionally resilient and the efficiency of investment must increase sharply. If rebalancing is too slow, the capital‐to‐output ratio will rise to potentially unsustainable levels and consumption will fail to attain levels of contemporary upper middle‐income economies by 2030. Global input–output tables (1995–2011) suggest that the patterns of Chinese rebalancing considered in our scenarios may generate substantial headwinds for exports to China by its trading partners.  相似文献

This paper links new firm survival with growth, with a focus on the patterns in firms' growth paths. We theorise a Gambler's Ruin framework by arguing that new firm performance is best modelled as a random walk process, but that survival is nonrandom and depends primarily on the stock of accumulated resources. A firm's resources are either there when the business begins or are generated by successful periods — ‘wins’. The empirical section tracks, over six years, the sales and survival/non-survival of 6247 UK start-ups which all began trading in the same quarter of 2004. We do not find strong evidence in favour of a taxonomy of growth paths, because we observe that every possible growth path seems to occur with roughly equal probability. However, we observe that growth paths influence subsequent survival. Controlling for lagged size, we observe that longer lags of growth, and even start-up size, have significant effects on survival.  相似文献

Over the last twenty years, both crop production and agricultural payments have shifted toward larger operations. This study examines whether payments from federal farm programs contributed to increased concentration of cropland and farmland. Using zip code–level data constructed from the microfiles of the 1987–2002 agriculture censuses we examine the association between government payments per acre and subsequent growth in land concentration. A semiparametric generalized additive model (GAM) controls for location and historical concentration, sales per acre, and ratio of cropland area to zip code area. Findings indicate, both with and without nonparametric controls, government payments are strongly associated with subsequent concentration growth.  相似文献

Agronomic analyses of new technologies are often conducted under carefully controlled research station programs or trials managed by self‐selected farmers. Oftentimes, the technologies are then scaled up with minimal evaluation under real‐world conditions. Yet, the interim step between agronomic trials and large‐scale promotion is crucial to generate evidence on the social and economic impact of technologies that is both internally valid and generalizable. The article focuses on a participatory action research program in Malawi designed to test and identify scalable technology options to intensify the smallholder sector and contribute to poverty reduction and food and nutrition security. We examine the socioeconomic characteristics of farmers testing technologies and find evidence of systematic targeting of better‐endowed farmers. After controlling for observable differences using matching and a doubly robust estimator, we find evidence of early positive effects on maize yield and harvest value, although placebo tests suggest possible selection on unobservables. We note that attention should be given to program design and household characterization to better define and improve targeting criteria, technology selection, and external validity.  相似文献
