Stability of the nonlinear dynamics of an optically injected VCSEL
Automated protocols have been developed to characterize time series data in terms of stability. These techniques are applied to the output power time series of an optically injected vertical cavity surface emitting laser (VCSEL) subject to varying injection strength and optical frequency detuning between master and slave lasers. Dynamic maps, generated from high resolution, computer controlled experiments, identify regions of dynamic instability in the parameter space. © 2012 Optical Society of America
Capital budgeting processes and techniques used by agricultural enterprises in Estonia
Investeeringutel on oluline mõju ettevõtte tuleviku rahavoogudele ja ettevõtte
(finants)tulemustele tulevikus. Seega on oluline, et ettevõttes vastuvõetavad otsused
oleksid strateegiliselt kaalutletud ning läbinud teatavad analüüsi- ja hindamisprotsessid.
Eesti põllumajandusettevõtted on viimastel aastatel olnud ühed aktiivsemad
materiaalsesse põhivarasse investeerijad. Kuna põllumajandussektori investeeringuid
iseloomustavad suured pöördumatud kulud ning kõrge määramatus tuleviku osas, on
oskus investeerimisprojekte hinnata ja analüüsida väga oluline.
Magistritöö eesmärgiks on välja selgitada, milline on Eesti põllumajandusettevõtete
kapitali eelarvestamise protsess ning milliseid kapitali eelarvestamise meetodeid
ettevõtted kasutavad.
Käesolev magistritöö koosneb kahest peatükist ning töös on kasutatud nii esmaseid kui
ka teiseseid andmeid. Töö empiirilises osas analüüsiti Eesti põllumajandusettevõtete
investeerimisaktiivsust, kasutades Eesti Statistikaameti ja FADN andmebaase, ning viidi
läbi ankeetküsitlus, et uurida, millised on kapitali eelarvestamise protsessid ja
kasutatavad meetodid põllumajandusettevõtetes. Uuringus osales 42 põllumajandusettevõtete.
Sarnaselt varem läbiviidud uuringutele tuli välja, et Eesti põllumajandusettevõtted
pööravad enam tähelepanu investeerimisvajaduste väljaselgitamisele ja
investeerimisotsuse täideviimisele, kui investeerimisprojekti tasuvuse hindamisele,
riskianalüüsi läbiviimisele ja tulemuste kontrollimisele. Investeeringute tasuvuse
hindamisel kasutatakse enamasti lihtsamaid meetodeid (tasuvusaeg ja arvestusliku
rentaabluse meetod). Suuremad põllumajandusettevõtted kasutavad keskmisest enam
keerukamaid kapitali eelarvestamise meetodeid (NPV, IRR) ning samuti hindasid
keskettevõtted keskmisest kõrgemalt oma teostust riskianalüüsi läbiviimisel.
Seega on oluline tõsta põllumajandusettevõtete finantsplaneerimise oskust läbi koolituste
ja nõuandeteenistuse ning toetada ja julgustada ettevõtteid keerukamate kapitali
eelarvestamise meetodite kasutamisel.
Edasistes uuringutes tuleks täpsemalt uurida, milliseid hindamiskriteeriume
põllumajandusettevõtted investeeringute tasuvuse hindamisel kasutavad; kuidas
teostatakse projekti riskianalüüsi. Samuti tuleks uurida, kas ja mil määral erinevad
kapitali eelarvestamise protsessid ja kasutatavad meetodid Eestis tegevusvaldkonniti.Capital budgeting is one of the most important decisions that enterprise’s (financial)
managers are facing with. Investments projects have an essential impact on enterprise’s
future cash flow and its’ financial position in the future. Therefore it is crucial that
managers use accurate capital budgeting techniques that help them to make the best
investment decision for the enterprise. In recent years, agricultural enterprises in Estonia
are actively investing in fixed assets. As investments in agriculture are typically
characterized by large sunk costs and uncertainty in future returns, it is very important
that investments decisions are evaluated and analysed properly.
The objective of this Master`s thesis is to identify what the capital budgeting process is
like in Estonian agricultural enterprises and which capital budgeting methods companies
use.
This Master`s thesis comprises two chapters and uses primary and secondary data. This
Master`s thesis comprises two chapters and uses primary and secondary data. The first
chapter gives a theoretical overview of the nature and processes of capital budgeting.
The second chapter assesses the investment activity of Estonian agricultural enterprises,
the database of Statistics Estonia and FADN were used as data sources; and describes the
methodology, sample, and results of the research conducted for the purpose of this
Master`s thesis. Forty-two agricultural enterprises participated in the empirical study.
The data show that in recent years, the investment activity of agricultural enterprises has
increased, but Estonian agricultural companies are still falling behind and have great
investment needs in comparison with the companies of other European Union Member
States. The results of the study revealed that agricultural enterprises pay more attention
to identifying investment needs and implementing investment decisions than to assessing
the profitability of an investment project, conducting risk analysis, and examining the
results. In appraising the profitability of investment projects, simpler evaluation
techniques, like payback period and accounting rate of return, are preferred. The
comparison of agricultural companies by size revealed that medium-sized companies use
more sophisticated capital budgeting methods (like NPV and IRR) and assess their risk
analysis processes to be above average.
Therefore it is important to increase the financial planning skills of agricultural
enterprises with trainings and advisory services, as well as to support and encourage the
companies to use more complex capital budgeting methods.
This Master`s thesis can be developed further in several directions. The further studies
should research in more detail which assessment criteria are used by agricultural
enterprises in evaluating the profitability of investments, as well as how companies
conduct project risk analyses. Another subject that should be examined further is how
and to which extent are various capital budgeting processes and methods used in
different fields of activity in Estonia
