                                PROXY STATEMENT
         ANNUAL MEETING OF SHAREHOLDERS TO BE HELD ON NOVEMBER 19, 1998
 
                            ------------------------
 
     This statement is furnished to the shareholders of Managed High Yield Fund
Inc. ('Fund') in connection with the board of directors' solicitation of proxies
to be used at the annual meeting of the shareholders of the Fund to be held on
November 19, 1998, or any adjournment or adjournments thereof. This proxy
statement and the related proxy card will first be mailed to shareholders on or
about October 1, 1998.
 
     A majority of the shares outstanding on September 18, 1998, represented in
person or by proxy, must be present for the transaction of business at the
meeting. In the event that a quorum is not present at the annual meeting, or if
a quorum is present at the annual meeting but sufficient votes to approve any of
the proposals are not received, the persons named as proxies may propose one or
more adjournments of the annual meeting to permit further solicitation of
proxies. Any such adjournment will require the affirmative vote of a majority of
those shares represented at the annual meeting in person or by proxy. The
persons named as proxies will vote those proxies which they are entitled to vote
FOR any such proposal in favor of such an adjournment, and will vote those
proxies required to be voted AGAINST any such proposal against such adjournment.
A shareholder vote may be taken on one or more of the proposals in this proxy
statement prior to any such adjournment if sufficient votes have been received
and it is otherwise appropriate.
 
     Broker non-votes are shares held in street name for which the broker
indicates that instructions have not been received from the beneficial owners or
other persons entitled to vote and for which the broker does not have
discretionary voting authority. Abstentions and broker non-votes will be counted
as shares present for purposes of determining whether a quorum is present but
will not be voted for or against any adjournment or proposal. Accordingly,
abstentions and broker non-votes effectively will be a vote against adjournment
but will have no effect on Proposals 1 and 2, for which the required vote is a
plurality and majority, respectively, of the votes cast.
 
     The individuals named as proxies on the enclosed proxy card will vote in
accordance with your direction as indicated thereon if your proxy card is
received properly executed by you or by your duly appointed agent or
attorney-in-fact. If you give no voting instructions, your shares will be voted
FOR the nine nominees for directors named herein and FOR the remaining proposals
described in this proxy statement. You may revoke any proxy card by giving
another proxy or by letter or telegram revoking the initial proxy. To be
effective, your revocation must be received by the Fund prior to the meeting and
must indicate your name and account number. In addition, if you attend the
meeting in person you may, if you wish, vote by ballot at the meeting, thereby
cancelling any proxy previously given.
 
     As of the record date, September 18, 1998, the Fund had 6,031,667 shares of
common stock outstanding. The solicitation of proxies, the cost of which will be
borne by the Fund, will be made primarily by mail but also may include telephone
or oral communications by regular employees of Mitchell Hutchins Asset
Management Inc. ('Mitchell Hutchins') or PaineWebber Incorporated
('PaineWebber'), who will not receive any compensation therefor from the Fund.
Management does not know of any person who owns beneficially 5% or more of the
shares of the Fund. Each full share of the Fund outstanding is entitled to one



vote and each fractional share of the Fund outstanding is entitled to a
proportionate share of one vote for such purposes.
 
     The Fund's annual report containing financial statements for the fiscal
year ended July 31, 1998, is being mailed concurrently to shareholders with this
proxy statement.
 
     Mitchell Hutchins serves as the Fund's investment adviser and
administrator. Mitchell Hutchins is a wholly owned asset management subsidiary
of PaineWebber, which is a wholly owned subsidiary of Paine Webber Group Inc.
('PW Group'), a publicly held financial services holding company. PaineWebber
may from time to time act as a dealer and secondary market-maker in connection
with over-the-counter secondary market sales of the Fund's common stock. The
principal business address of each of Mitchell Hutchins, PaineWebber and PW
Group is 1285 Avenue of the Americas, New York, New York 10019.
 
                       PROPOSAL 1. ELECTION OF DIRECTORS
 
     Proposal 1 relates to the election of directors of the Fund. Management
proposes the election of the nine nominees named in the table below. Each
nominee, including those who are not 'interested persons' of the Fund as that
term is defined by the Investment Company Act of 1940 ('1940 Act') ('Independent
Directors'), has indicated his or her willingness to serve if elected. If
elected, each nominee will hold office until the next annual meeting of
shareholders or until his or her successor is elected and qualified. Unless you
give contrary instructions on the enclosed proxy card, your shares will be voted
FOR the election of the nine nominees. If any of the nominees should withdraw or
otherwise become unavailable for election, your shares will be voted FOR such
other nominee or nominees as management may recommend.
 
     Mr. Bewkes has served as a director from the Fund's inception except for a
brief period during 1993. Messrs. Armstrong and Burt have served as directors of
the Fund since 1995. Each of the other directors was first elected to the board
on April 11, 1996. Directors will be elected by the affirmative vote of the
holders of a plurality of the votes cast for the election of directors, present
in person or by proxy and entitled to vote thereon, provided a quorum is
present. If each of the nine nominees is elected, they will constitute the
entire board of directors of the Fund. None of the directors and executive
officers (20 persons) beneficially owned any shares of the Fund on August 31,
1998.

     The board of directors of the Fund met six times during the fiscal year
ended July 31, 1998. Each of the directors attended 75% or more of the board
meetings during the last fiscal year. The Audit and Contract Review Committee
('ACR Committee') of the board currently consists of Messrs. Armstrong, Burt,
Feldberg, Gowen, Malek and Schafer. The ACR Committee has established a
sub-committee that periodically reviews the contractual and audit arrangements
for the Fund and reports back to the full ACR Committee. Messrs. Burt, Feldberg
and Schafer are members of this sub-committee. Each member of the Fund's ACR
Committee is also a member of a similar committee established by the boards of
other investment companies for which Mitchell Hutchins or PaineWebber serves as
investment adviser and also may be a member of a sub-committee established by
another fund's audit and contract review committee. The duties of the ACR
Committee are: (a) to review the financial and accounting policies of the Fund,
including internal accounting control procedures, and to review reports prepared
by the Fund's independent auditors, including reports on the Fund's financial
statements; (b) to review and recommend approval or disapproval of audit and
non-audit services and the fees charged for such services; (c) to evaluate the
independence of the independent auditors and to recommend whether to retain such
independent auditors for the next fiscal year; and (d) to report to the board
and make such recommendations as it deems necessary. The ACR Committee and the
related sub-committee each met once during the fiscal year ended July 31, 1998.
Each member of the ACR Committee and sub-committee attended those meetings.
 
     The board does not have a standing nominating or compensation committee.
The Fund pays the Independent Directors $1,000 annually and $150 for each board
meeting and for each separate meeting of a board committee. The chairmen of the
audit and contract review committees of individual funds within the PaineWebber
fund complex receive additional compensation aggregating $15,000 annually from
the relevant funds. Directors of the Fund who are 'interested persons' as
defined in the 1940 Act receive no compensation from the Fund. Directors are
reimbursed for any expenses incurred in attending meetings. Each director will
be subject to mandatory retirement at the end of the year in which he or she
becomes 72 years old. The board has waived this requirement with respect to Mr.
Bewkes for the next year. The table below includes certain information relating
to the compensation of the Fund's directors.

         PROPOSAL 2. RATIFICATION OF SELECTION OF INDEPENDENT AUDITORS

were audited by Ernst & Young LLP ('Ernst & Young'), independent auditors. In

returns.
 
     The board of directors of the Fund has selected Ernst & Young as the
independent auditors for the Fund for the fiscal year ending July 31, 1999,
subject to ratification by shareholders of the Fund at the annual meeting. Ernst
& Young has been the Fund's independent auditors since its inception in
December 1993. The ratification of Ernst & Young as independent auditors is to
be voted upon at the annual meeting, and it is intended that the persons named
in the accompanying proxy will vote FOR such ratification unless contrary
instructions are given. Ernst & Young has informed the Fund that it has no
material direct or indirect financial interest in the Fund. The affirmative vote
of the holders of a majority of the shares of the Fund cast at the annual
meeting is required for ratification, provided a quorum is present.
 
     Representatives of Ernst & Young are not expected to be present at the
meeting but have been given the opportunity to make a statement if they so
desire and will be available should any matter arise requiring their presence.
