The Hubs Research Project is a full-length academic paper analyzing the effectiveness of "hubs", a component of the entrepreneurship ecosystem, in the advancement and growth of entrepreneurial success in a metropolitan area.

This research will primarily focused on large and mid-sized Metropolitan Statistical Areas (MSAs), as that is where the greater majority of Venture Capital funding is located.

Primary Data Set

The Hubs data set, from SDC Platinum, has been constructed in the server:

Data files are in 128.42.44.181/bulk/Hubs
All files are in 128.42.44.182/bulk/Projects/Ecosystem/Hubs
psql Hubs

The data set includes all United States Venture Capital transactions (moneytree) from the twenty-five year period of 1990 through 2015. Data has been aggregated at the portfolio company, fund, and round level. It will be analyzed at the combined MSA level. We will be looking at in terms of number of companies funded in number of funds active, and flow of investment in a given MSA.

The data set has now been uploaded to the database server, named Hubs. There are 4 tables:

• Rounds: Rounddate, coname, state, roundno, stage1, etc.
• CombinedRounds: Coname, rounddate, discamount, fundname
• Companies: LastInv, FirstInv, coname, MSA, MSACode, Address, state, datefounded, totalknownfunding, industry(major)
• Funds: fundname, closingdate, lastinv, firstinv, msa, msacode, avinv, nocoinv, totalknowninv, address

Used variables:

Companies: Coname, MSACode, Industry, state
MSALookupTable: MSACode, MSASuper
IndustryLookupTable: IndustryMajor, InduCode
-> 
CompanyInfo: Coname, MSASuper, InduCode, state (complete)

Funds: fundname, msacode, state
MSALookupTable: MSACode, MSASuper 
-> 
FundInfo: fundname, msacode, state (complete)

Rounds: coname, rounddate, stagecode, roundno
CombinedRounds: coname, rounddate, discamount, fundname
->
RoundInfoSuper: coname, rounddate, nofunds, discamount   
->
RoundInfo: Coname, roundyear, fundname, estamount (complete)

Then take:

RoundInfo: Coname, roundyear, fundname, estamount
CompanyInfo: Coname, MSASuper, InduCode, state
FundInfo: fundname, msacode, state
->
SuperRoundInfo: Coname, CoMSASuper, CoInduCode, CoState, FundName, FundMSASuper, FundState, RoundYear, RoundEstAmount
->
MSAPortCos: Count(CoName) As NoPortCosFunded, CoMSASuper, RoundYear
...

Notes on Creation of Primary Data Set

Raw tables

• companies (last investment, first investment, company name, MSA, MSA code, address, state, date founded, known funding, industry)
• funds (fund closing date, last investment, first investment, fund name, address, MSA, MSA code, Average investment, number companies invested (NoCos), known investment)
• rounds (round date, company name, state, round number, stage 1, stage 2, stage 3)
• combined rounds (company name, round date, disclosed amount, investor)
• msalist (changes MSAs to CMSAs— combined MSAs)
• industry list (changes 6 industry categories to 4— ICT, Life Sciences, Semiconductors, Other)

Process

• cleaned tables to eliminate duplications, undisclosed variables
• changed all original characters to include CMSA and Industry Codes (companyinfo3, fundinfocleanfinal, roundinfoclean)
• matched funds to avoid any issues with names (i.e. Fund ABC L.P./Fund ABC LP/Fund ABC)
• matched roundinfoclean investors to fundinfocleanfinal investors (roundinfo.txt >> cleanfundfinal.txt)
• join by round and company conames
• bridge years (1990-2016), stage, and cmsa
• populate data with count of companies (Deal flow) and estimated amount ($)
  • data set in 181 hubs folder under summarycmsa.txt (38394)

Key decisions:

• Threw out undisclosed co through-out as no address
• Count is done by joining round and company
• Anything fund related must be disclosed fund
• Near and far, and total invested, and fund counts, etc., are all done using disclosed funds that match only

Hub Candidates Data Set

The Hubs candidate data set is a list of potential hubs found in MSAs throughout the country. Researchers are currently pulling qualitative and quantitative information from the candidate's websites, in an attempt to categorize what can be identified as a hub. This is a difficult data set to pull, as there is little to no quantitative information available for this category of institution, and is dependent on accessibility of information to the public on the internet.

Characteristics/Variables

• Year Founded
• Square footage
• LinkedIN self-identifiers (what the organization classifies itself on its LinkedIN profile)
• Activeness on Twitter (binomial)
• Member Directory available online (binomial)
• Number of conference rooms
• Price ($/month) for Flex desk
• Offers Reserved desk (binomial)
• Offers office space for rent (binomial)
• Offers community membership-- not for coworking but for community events, etc. (binomial)
• Number of events offered per month (estimate)
• Offers code academy
• Mission Statement/Vision (for qualitative or key-word analysis)

These characteristics/variables will be used to determine whether a candidate is or is not likely to be a Hub.

As of March 10th 2016, the list contains 125 Hub candidates.

Where to find: The Hubs data set can be found in the Ecosystem>>Hubs>>dataset folder. It is not currently in the database due to a UTF8 issue

Supplementary Data Sets

Patent data: to be pulled from USPTO or SDC Platinum.

Number of STEM Graduate Students (NSF) and University R&D Spending (NSF):

• University R&D Data found under file "NSF DATA_2004 to 2011.xlsx" in datasets folder (Ecosystem>>Hubs>>Datasets)
• R&D spending found at the university level for 2014 ("Stem Grad Students.xlsx) or at state level ("Science and Engineering Grad Students by State and Year 2000-2011.csv")
  • not uploaded to server or matched yet to CMSA code, because of this discrepancy.
  • "Stem Grad Students.xlsx" contains categorized university by MSA, can be used for all university-based projects

Per Capita Income and Employment Data (US Census Bureau):

• "Per Capita Personal Income by MSA 2000-2012.xlsx" in datasets folder (Ecosystem>>Hubs>>Datasets>>Data from Yael)
• "Wages and Salaries by MSA 2000-2012.xlsx" in datasets folder (Ecosystem>>Hubs>>datasets>>Data from Yael)
  • not uploaded to server or matched yet to CMSA code

Firm Births (BDS)

• in server 181, under table name "BDS"
• includes birth, death, net(birth-death) and rate(death rate) for years 1990-2013 for every msa
• includes code for CMSA but is not aggregated by CMSA
  • i.e. BDS statistics are still separate for all the smaller MSAs in New York's CMSA (code=1)

The Target Dataset

We will need to process the following variables:

• SuperMSA - combine SanFran and SanJose, New York and Newark?, NC Research triangle, others?
• CSV mapping msas to cmsas is in the folder (and a table in the dbase)

Example dataset:

MSA      Year       SeedVCInv      SeedEarlyVCInv      LaterVCInv     NoDeals   FundsInvested   DistinctInvestors   ....
----------------------------------------------------------------------------------------------------------------------------
1234     2001       1000000        20000000            30000000       4          7              7

Note that the unit of observation is MSA-Year.

Variables to be computed at the MSA level:

• HubActive (binary)
• NoHubsActive (Count)
• HubSqFt
• Other Hub Vars (build list!!!)
• SeedVCInv (Seed/Start-up)
• EarlyVCInv (Early Stage)
• LaterStageVC (Later)
• OtherStageVC (Buyout/Acq, Other)
• NoDeals (done by local VCs?)
  • NoDealsNear
  • NoDealsFar
• NoPortCosFunded
• FundsInv (in an MSA)
  • FundsInvFromNear (within MSA?)
  • FundsInvFromFar (outside MSA?)
• DistinctInvestors (?)
  • DistinctInvestorsNear (within MSA?)
  • DistinctInvestorsFar (outside MSA?)
• PatentCount
• NoSTEMGrads
• FirmBirths (BDS data)
• UniRandDSpend
• PerCapitaIncome
• Employment

We need to:

• Check funds invested means dollars invested
• Categorize near and far! Is it within MSA vs. not, within adjacent MSAs, etc.?

There may be a second dataset that has Hub-Industry-Year (where industry is semiconductor/non-semiconductor?).

Final Primary Data Set

• Deal is a round syndicate (near/far deal is one investor that is near/far).

Data by MSA

We have principle cities of MSAs from the census: https://www.census.gov/geographies/reference-files/time-series/demo/metro-micro/delineation-files.html

We might be able to go City -> FIPS place code -> MSA?

Cities and their FIPS codes (which don't perfectly correspond) are available from https://www.census.gov/geo/reference/codes/place.html

The Census claims to provide city to MSA here: https://www.census.gov/geo/maps-data/data/ua_rel_download.html However, there is only CBSA!

This might do it: https://www2.census.gov/geo/pdfs/maps-data/data/rel/explanation_ua_cbsa_rel_10.pdf We can maybe track city to principal city to MSA
