Driving business performance: innovation complementarities and persistence patterns
Complementarities between technological and non-technological
innovation are crucial determinants of firm performance. This
topic has not received the attention that it merits, as the focus
has been primarily placed on technological innovation alone or
on innovation efforts as measured by R&D or patent activities.
The capacities to develop market-oriented behaviour and introduce
new organisational innovations are the drivers - together
with technological innovation - of a firm\u2019s productivity and profitability.
We also underline how the impact of such activities is
larger when they persist over time, thus introducing a more general
concept of innovation persistency. We present an empirical
model based on a large and new panel of Italian manufacturing
firms covering the period 2000-2012 that enables us to derive
the precise impacts of a firm\u2019s innovative effort - based on a
broad definition that incorporates non-technological innovation
and persistence - on its productivity and profitability
Persistent Product Innovation and Market-oriented Behaviour:the Impact on Firms'Performance
f innovation on firms\u2019 economic performance pinpointing complementarities
between product and marketing innovation during
the period 1998-2008. Firms\u2019 profitability and productivity
are simultaneously estimated, thus allowing for consistent and
robust estimates of the relationship being tested. The conceptual
framework in which we have developed the analysis bridges
the gap between the management (organization) approach, from
which we grasp the notion of a firm\u2019s market orientation to innovation,
and the economics of innovation perspective. The results
show that being a persistent product-innovating and marketoriented
firm significantly affects profitability, although the estimated
impact is relatively mild. The gain in productivity determined
by investing in R&D is relatively small and in line
with the corresponding gain attributable to investing in marketing
and organizational innovations. Conversely, capital deepening\u2014
as measured by the capital-labor ratio\u2014exerts a larger
impact on productivity, thus underlining how knowledge capital
plays a less relevant role. This result emphasizes a crucial
weakness of Italian manufacturing firms, because knowledge investment
is the key to future economic growth. The estimates
we have presented cover a sufficiently long time interval, thus
enabling us to perform different robustness tests
Antimicrobial susceptibility and emerging resistance determinants (blaCTX-M, rmtB, fosA3) in clinical isolates from urinary tract infections in the Bolivian Chaco
Summary Background Bolivia is among the lowest-resourced South American countries, with very few data available on antibiotic resistance in bacterial pathogens. The phenotypic and molecular characterization of bacterial isolates responsible for urinary tract infections (UTIs) in the Bolivian Chaco are reported here. Methods All clinical isolates from UTIs collected in the Hospital Basico Villa Montes between June 2010 and January 2014 were analyzed ( N =213). Characterization included susceptibility testing, extended-spectrum beta-lactamase (ESBL) detection, identification of relevant resistance determinants (e.g., CTX-M-type ESBLs, 16S rRNA methyltransferases, glutathione S-transferases), and genotyping of CTX-M producers. Results Very high resistance rates were observed. Overall, the lowest susceptibility was observed for trimethoprim–sulphamethoxazole, tetracycline, nalidixic acid, amoxicillin–clavulanic acid, ciprofloxacin, and gentamicin. Of E. coli and K. pneumoniae , 11.6% were ESBL producers. Resistance to nitrofurantoin, amikacin, and fosfomycin remained low, and susceptibility to carbapenems was fully preserved. CTX-M-15 was the dominant CTX-M variant. Four E. coli ST131 (two being H30-Rx) were identified. Of note, isolates harbouring rmtB and fosA3 were detected. Conclusions Bolivia is not an exception to the very high resistance burden affecting many South American countries. Optimization of alternative approaches to monitor local antibiotic resistance trends in resource-limited settings is strongly encouraged to support the implementation of effective empiric treatment guidelines
Methicillin-resistant Staphylococcus aureus in hospitalized patients from the Bolivian Chaco
Summary Objectives Information is lacking on the methicillin-resistant Staphylococcus aureus (MRSA) clonal lineages circulating in Bolivia. We investigated the prevalence and molecular epidemiology of S. aureus colonization in hospitalized patients from the Bolivian Chaco, and compared their features with those of the few clinical isolates available from that setting. Methods S. aureus nasal/inguinal colonization was investigated in 280 inpatients from eight hospitals in two point prevalence surveys (2012, n =90; 2013, n =190). Molecular characterization included genotyping ( spa typing, multilocus sequence typing, and pulsed-field gel electrophoresis), detection of virulence genes, and SCC mec typing. Results Forty-one inpatients (14.6%) were S. aureus nasal/inguinal carriers, of whom five were colonized by MRSA (1.8%). MRSA isolates mostly belonged to spa- type t701, harboured SCC mec IVc, and were negative for Panton–Valentine leukocidin (PVL) genes. However, a USA300-related isolate was also detected, which showed the characteristics of the USA300 Latin American variant (USA300-LV; i.e., ST8, spa- type t008, SCC mec IVc, presence of PVL genes, absence of arc A). Notably, all the available MRSA clinical isolates ( n =5, collected during 2011–2013) were also identified as USA300-LV. Conclusions Overall, MRSA colonization in inpatients from the Bolivian Chaco was low. However, USA300-LV-related isolates were detected in colonization and infections, emphasizing the importance of implementing control measures to limit their further dissemination in this resource-limited area
Waiting for Godot: the failure of SMEs in the Italian Manufacturing Industry to grow
We use a panel of Italian manufacturing firms for the period
2001-2014 to analyse the distribution of firm size, and then test
for the validity of Gibrat\u2019s law using unit root tests. Although
Gibrat\u2019s Law is rejected and the estimates suggest that small
firms grow faster than larger ones, we do not observe a significant
change in the average size of companies at the end of the
period under investigation. Also, by using a long-run Transition
Probability Matrix, we verify that the steady-state distribution
of firm size remains stable. The higher propensity to grow shown
by smaller firms is confined to the size class in which the firm
is established. We further investigate the relationship between
the rate of growth in a firm\u2019s size conditional on specific firm
and industry characteristics. Export intensity plays a significant
role in affecting the size growth rate together with industry
characteristics related to technological levels. Finally, we estimate
the probability that a firm increases in size relative to the
mean size prevailing in its own size class over a 14-year interval.
This approach enables us to highlight those factors that affect
this probability, thereby enabling us to underline how Gibrat\u2019s
Law tests, although important, require complementary analysis
to ascertain whether a firm\u2019s propensity to increase in size is a
long run effect and thus a significant modification of the distribution
of company size or only implies a marginal increase in
size within a reference size class
